Introduction:
Welcome to Guardians of the Galaxy, a third person action-adventure game that is largely narrative driven, but full of big fights too. Note that this game is not related to the Marvel movies nor to the Telltale game. It is a standalone game about the Guardians, but with many familiar characters. Be prepared for an interesting and engaging story, an awesome soundtrack, big battles, epic boss fights, and more. Despite the huge number of achievements, a whopping 30 of them are story related and can't be missed, with a few more essentially story related since you'll unavoidably end up unlocking them. There are a few achievemnts related to collectibles, and then a bunch of combat achievements. While there is Chapter Select and therefore no achievements are missable, you can save yourself quite a bit of time by keeping an eye on certain things. More on that below; let's get started.

Abbreviated Walkthrough:
As noted above, while no achievements are technically missable, the first and most important achievement to be aware of is Galactic Frugality (15G) because it spans so many chapters. You'll unavoidably get fined by Nova Corps in Chapter 2, but you'll then need to ensure you collect enough units in Chapter 4, ensure you don't spend too many in Chapter 6 so you still have enough for your fine, and then ensure you actually select the options in Chapter 9 to pay off that fine. There isn't anything difficult about it, just don't forget about it as you progress.

The next thing to note are collectibles. There are essentially four types of collectibles in this game:

Outfits - There are 30 non-story ones and you must find all of them. A video guide is located in Fashion Passion (30G)
Archives - There are 42 of them but you only need to find 28 (i.e. 65%) for Lore Hoarder (30G). A video guide is available in Managerial Skills (30G)
Guardian Collectibles - There are 15 but you only need a total of 8 and all of one Guardian's collectibles. Managerial Skills (30G) has more information and a video guide
Items - There are 7 Items that aren't story related, and you actually don't need to collect any of them for any achievements (there are enough story-related ones and Guardian Collectibles to cross the 65% threshold)

One other thing that is somewhat collectible related are the parts you can loot around the levels to be used at workbenches for crafting perks. There are a total of 15 perks available to craft in the game, but only one - Charged Shot (the first one on the list) is needed for an achievement (Set 'em Up, Knock 'em Down (15G)). All of the rest of the perks can be crafted in whatever order is your preference, or you can choose to ignore components entirely if you wish (especially once you have all of the useful perks and don't see a need for any remaining ones).

With that out of the way, the final type of achievements is combat achievements. There are many of them, many of which are only available in a select chapter or after a certain chapter. There are also a couple miscellaneous achievements in specific chapters. To save you chapter replay, here is a quick breakdown of which chapters have achievements tied to them, so you can jump to them in the guide when you get to that chapter.

Chapter 1
Eat It, Rodent (15G)

Chapter 2
Galactic Frugality (15G) (Part 1)

Chapter 3
Slakebuster (15G)

Chapter 4
Galactic Frugality (15G) (Part 2)

Chapter 6
Galactic Frugality (15G) (Part 3)

Chapter 7
No Way, Nova Corps (15G)
Drax the Dismemberer (15G) (First of many opportunities)

Chapter 9
Galactic Frugality (15G) (Part 4)

Chapter 10
Groot Canal (15G) (First opportunity)

Chapter 11
Boom Show (15G) (First becomes available)

Chapter 12
Adding Injury to Insult (15G) (First becomes available)
Trained to Perfection (15G) (First becomes available)

Chapter 13
Groot Canal (15G) (Second opportunity)

Chapter 14
Herbal Remedy (15G) (First becomes available)

And that's really all of the information you need. Enjoy the story - you will get the vast majority of the achievements naturally as you play. Following the video guides for the collectibles might sound annoying, but they'll save you a decent amount of time and they don't contain any spoilers. If you miss anything, you can use Chapter Select from the main menu to go back and get any achievements, collectibles, etc.

Conclusion:
Guardians of the Galaxy is a surprisingly good game, which I think most people weren't expecting. It has a great and pretty lengthy story, tons of good dialogue, the usual hilarious banter and exchanges you can expect from these characters, an awesome song list that you'd come to expect from Peter Quill, epic boss fights, and some very fun combat that really becomes much more enjoyable as you unlock more and more abilities as you progress. The collectibles aren't too bad, in my opinion, since not too many are required for achievements and you have some leeway, plus the Outfits, which are all required, make your Guardians look pretty cool. I definitely recommend this game to any Marvel fans, as you'll certainly feel like you're playing through a full-blown Guardians adventure. Hopefully you enjoyed the game and congrats on the completion!

Self-Improvement

15
Purchase your first Star-Lord Ability.
Story-related; cannot be missed.

During Chapter 1 you will unavoidably amass enough XP to purchase your first Star-Lord ability, and the game will walk/force you through doing so.
Dynamic Team

15
Invest in at least one Special Ability for Gamora, Drax, Rocket and Groot.
Refer to Fully Loaded (15G) for more information.
Fully Loaded

15
Invest in all Special Abilities for all Companions.
(1)
This achievement requires you to buy all three abilities for Star Lord, buy the remaining two abilities for each of the other four Guardians, and then unlock the final ability for all five Guardians. The final ability for all five Guardians is unlocked automatically through story progression; the rest require ability points. As a result, you will need 26 ability points to unlock all Special Abilities and this achievement.

Despite seeming like a large amount of points, especially early in the game, this achievement is actually essentially progression related. There are no optional ways to gain XP towards ability points. All combat in the game is mandatory. On top of that, XP from combat is a set amount regardless of how many enemies you fight and kill. While your Momentum bonus can give you more XP, it's not often a significant amount, plus it's pretty difficult to finish a fight without at least a moderate Momentum bonus.

As a result, you will unavoidably get enough ability points to unlock all Abilities before you complete the game. I unlocked them all by Chapter 13, and there are a ton of fights in Chapter 14.
Flash Freeze

15
Acquire the Ice Element for Star-Lord's guns.
Story-related; cannot be missed.

This will unlock automatically during Chapter 4.
Shock and Awe

15
Acquire the Lightning Element for Star-Lord's guns.
Story-related; cannot be missed.

This will automatically unlock early in Chapter 7.
Fan Friction

15
Acquire the Wind Element for Star-Lord's guns.
Story-related; cannot be missed.

This will automatically unlock relatively early in Chapter 10.
Lava Launcher

15
Acquire the Plasma Element for Star-Lord's guns.
Story-related; cannot be missed.

This will unlock automatically during Chapter 13.
Pick Me Up

15
Revive a fallen team member.
During any combat encounter in the game, there is a possibility for one of your allies to take enough damage that they go down on one knee and glow red. If playing on the easiest difficulty, this is unlikely to happen against normal enemies but is pretty likely during boss fights. If one goes down, you'll get an on-screen prompt to help them. They will be glowing red. Approach and hold to heal them, reviving them and unlocking this achievement.
Stagger Swagger

15
Stagger 25 enemies.
As the game describes in an early tutorial, you can stagger enemies by filling up the white meter underneath their health, at which point they will glow a sort of orange color and be vulnerable to a lot of damage. This achievement requires you to stagger a cumulative total of 25 enemies.

This achievement is essentially progress related and can't be missed. While your allies do have abilities to stagger enemies, I unlocked this achievement very early in my playthrough without even trying. Some bosses require you to stagger them, and some abilities you'll be using, such as Groot's and Drax's, will stagger enemies immediately. Additionally, the Eye of the Hurricane ability that Quill has does an area of effect attack that automatically staggers all enemies around you. You will almost assuredly stagger more than enough enemies for this achievement before you even unlock that ability, but once you do unlock it and work on its achievement, you will end up staggering plenty more enemies.
No Way, Nova Corps

15
Interrupt a Nova Centurion with Gamora's Call to Action.
Chapter 7

During this chapter, you will fight against Nova Corps members (blue outfits). Around halfway through the chapter you'll focus on a bigger tougher Nova enemy that takes way more damage. This is the Nova Centurion (unfortunately, this enemy isn't added to your compendium, so I can't provide a screenshot).

As with all of the achievements for interrupting an enemy with a specific character's Call to Action, you need to weaken the enemy and fill up their Stagger meter. The best abilities to stagger enemies are Drax's abilities and Quill's Eye of the Hurricane ability. Once they are staggered, you will get a prompt while looking at them. Do so, and one of your allies will do a Call to Action. You unfortunately have no control over which ally attacks, so if it isn't Gamora for this achievement, you can reload your checkpoint to try again.
Slakebuster

15
Interrupt a Slakebeast with Drax's Call to Action.
(1)
Chapter 3

During this chapter you will fight against a large beast with a tentacle face (pictured below), and then later in this chapter you will face off against two of them.

As with all of the achievements for interrupting an enemy with a specific character's Call to Action, you need to weaken the enemy and fill up their Stagger meter. The best abilities to stagger enemies are Drax's abilities and Quill's Eye of the Hurricane ability. Once they are staggered, you will get a prompt while looking at them. Do so, and one of your allies will do a Call to Action. You unfortunately have no control over which ally attacks, so if it isn't Drax for this achievement, you can reload your checkpoint to try again.
Groot Canal

15
Interrupt a Charger with Groot's Call to Action.
Chapter 10

There are actually multiple enemies that qualify for this achievement, with the first being in Chapter 10 (the enemy pictured in the achievement image is a Wendigo from Chapter 13, who also qualifies). The enemy pictured below shows up multiple times in Chapter 10.

As with all of the achievements for interrupting an enemy with a specific character's Call to Action, you need to weaken the enemy and fill up their Stagger meter. The best abilities to stagger enemies are Drax's abilities and Quill's Eye of the Hurricane ability. Once they are staggered, you will get a prompt while looking at them. Do so, and one of your allies will do a Call to Action. You unfortunately have no control over which ally attacks, so if it isn't Groot for this achievement, you can reload your checkpoint to try again.
Drax the Dismemberer

15
Dismember an Inquisitor with Drax's Call to Action.
(1)
Chapter 7 (and many others after)

The Inquisitor enemy first makes its appearance in Chapter 7, but then shows up in many chapters for the rest of the game. The screenshot below shows what they look like.

As with all of the achievements for interrupting an enemy with a specific character's Call to Action, you need to weaken the enemy and fill up their Stagger meter. The best abilities to stagger enemies are Drax's abilities and Quill's Eye of the Hurricane ability. Once they are staggered, you will get a prompt while looking at them. Do so, and one of your allies will do a Call to Action. You unfortunately have no control over which ally attacks, so if it isn't Drax for this achievement, you can reload your checkpoint to try again.
Unstoppable Force

15
Attain the maximum possible Momentum 10 times.
Momentum builds up during combat from any attacks that connect, and builds faster the more varied your attacks are (various ally abilities, shooting, elemental attacks, melee, etc.). If you go too long without hitting an enemy (you actually have a pretty long amount of time) your meter will start to drop pretty quickly. Additionally, certain enemy attacks (Inquisitor eye laser, for example) will automatically drop you down one level of momentum, so be careful of them. Counterintuitively, getting hit doesn't impact your momuntum meter, in general. The meter progresses as follows:
- Fantastic
- Amazing
- Uncanny
- Incredible
- Marvelous
For this achievement, you need to reach a Marvelous momentum ten times cumulatively. In the beginning few chapters of the game this won't even be possible, since there aren't enough enemies and you don't have many abilities. However, from around Chapter 6 or 7 onwards, fights are pretty big and enemies can take a lot more damage, so you will have many, many opportunities to reach maximum momentum. Additionally, there are many fights that involve infinitely spawning enemies. You could, if absolutely need be, farm enemies until you maximize your momentum before finishing the fight. Later fights are big enough that you can literally just shoot your gun the entire time to maximize your momentum meter, but of course any ally abilities you use will make it fill up even faster.
The Crowd Goes Wild

15
Execute a Flair Attack 10 times.
Flair Attacks are one of the things the game doesn't tell you about at all - when an enemy gets lower in health, you may see a prompt above their head (it could be faint if you're farther away) that says + . You need to get in relatively close and press the combination of buttons, and you'll execute a melee finisher with an ally. This is a Flair Attack that counts for this achievement.

Flair Attacks, in my experience, don't seem possible on regular enemies. It always needed to be at least a "medium" enemy or tougher for me to get the prompt above their heads. I routinely got them for the yellow-shirted converted enemies, and I often got the prompt for Inquisitors. As long as you pay attention and take advantage of this prompt each time it pops up (especially since it's an instant kill), you will unlock this achievement long before finishing the game.
Set 'em Up, Knock 'em Down

15
Defeat 15 Staggered enemies with a Charged Shot.
This is one of the more annoying achievements since Charged Shot is pretty awkward and inconvenient to use, especially when you need to use it quickly.

First, you'll need to purchase/craft Charged Shot from a workbench when you have enough parts (this will be introduced near the end of Chapter 1). Once you create the Charged Shot perk, you can double tap and hold to charge up a shot, then release to shoot, doing moderate damage.

With that perk available, you then need to Stagger an enemy, who either already has their health lowered significantly or you can try to do so after they're Staggered, and then charge up a Charged Shot and finish them off with it. Enemies typically only stay Staggered for five seconds, and it takes a couple seconds to charge up a Charged Shot, making it pretty tight timing to contribute towards this achievement. As a result, you should focus on this as soon as possible unless you want to just grind it out (more on that below).

By far, in my opinion, the easiest way to work on this achievement is to make use of Quill's Eye of the Hurricane ability where he throws grenades around him. These automatically stagger all normal enemies they hit. On top of that, many enemies also take enough damage from the grenades such that a Charged Shot will kill them. When you land, you then have enough time to finish at least one enemy with a Charged Shot, or two if you're good at using Charged Shot. Pretty much every combat encounter that would start, I would dash into the starting group of 2-4 enemies, use Eye of the Hurricane, and get one or two kills towards this achievement.

You can, however, grind this out in a single combat encounter if you just want to get it out of the way. Use the approach I mentioned above (charge into a group of enemies, use your grenades to stagger them all, then use Charged Shot on one or two), then load your last checkpoint to start the fight over and repeat until you unlock this achievement.
Bullet Hell

15
Defeat 15 enemies with Star-Lord's Fan the Hammer ability.
This ability requires two ability points to unlock. It locks you in place (you can still turn and aim) while you unload a massive amount of bullets for a few seconds.

This achievement is quite easy to unlock because of how quickly this ability can kill normal enemies. You can easily kill three or four regular enemies with a single usage. It's especially effective to let enemies group up and just fire into their group. Defeat 15 cumulatively to unlock this achievement.
Adding Injury to Insult

15
Defeat 10 enemies affected by Drax's Wrath of Katath ability.
This ability automatically unlocks during Chapter 12. It essentially applies a huge amount of Stagger to an enemy and moderate Stagger to nearby ones. For this achievement, you simply need to kill those enemies while they are Staggered.

While this ability unlocks quite late in the game, it's pretty easy to get kills for this achievement. Using this ability on/around regular enemies makes it very quick and easy to simple gun them down to finish them off. Alternatively, you can use this Drax ability to Stagger enemies followed immediately by Rocket's grenade to kill all enemies in the area.

As with other combat achievements, you could grind this in a single combat encounter by using the ability and getting kills, then reloading your checkpoint to repeat until you unlock this achievement.
Trained to Perfection

15
Defeat 10 enemies with Gamora's Executioner ability.
This ability automatically unlocks during Chapter 12. It does a massive amount of damage to a single enemy. For this achievement, simply kill 10 enemies cumulatively with this ability.

All regular enemies will die instantly from this ability. Medium and heavy enemies will require you to damage them enough first. However, as long as you keep at it with this ability (and you will assuredly be making good use of it in the fights from Chapter 12 onwards), you will unlock this achievement very quickly because of how easily Gamora kills enemies with it.

As with other combat achievements, you could grind this in a single combat encounter by using the ability and getting kills, then reloading your checkpoint to repeat until you unlock this achievement.
Boom Show

15
Defeat 20 enemies with Rocket's Five Barrel Barrage.
This ability unlocks automatically during Chapter 11. Rocket pulls out a massive amount of guns and shoots bullets and rockets in the general vicinity of where you were targeting (he covers quite a wide area). You'll need to kill 20 enemies cumulatively for this achievement.

Regular enemies will quite possibly be killed entirely from a usage of this ability, but it depends on how mobile they are and if they get caught in Rocket's hectic fire. It's definitely more effective to weaken them a bit first, just to be safe. Shortly after unlocking this ability you will be in combat with an infinite amount of slug-like enemies, giving you a very easy opportunity to grind out this achievement if you'd like. There are, however, many large combat encounters throughout the rest of the game to work on this achievement.

As with other combat achievements, you could grind this in a single combat encounter by using the ability and getting kills, then reloading your checkpoint to repeat until you unlock this achievement.
Herbal Remedy

15
Revive or Heal Companions 10 times with Groot's Gift of the Florae.
(1)
This ability unlocks automatically at the start of Chapter 14. This ability can either be used directly from the ability wheel like any other ability, or it can trigger automatically if you get killed. Regardless of how this ability triggers, it will always impact every Guardian, not just one. So, for example, if this ability triggers when you die, you will get revived (counting as one of the ten times for this achievement) and any allies who have been damaged will also be healed (potentially counting another four times of the ten times for this achievement). As a result of this, you will unlock this achievement in three usages of this ability, most likely. I personally just saved it for if I got killed, and each time I was revived I made 40% progress towards this achievement. If you wait for an ally to get downed and use the ability, you can guarantee the rest of your allies have also been damaged and will get healed too, contributing even more toward this achievement.
Altitude Adjustment

15
Defeat 20 enemies with Star-Lord's Eye of the Hurricane.
The Eye of the Hurricane ability is Quill's third ability and costs three ability points to unlock. He jumps in the air and throws grenades all around him. They do moderate damage and heavy Stagger to all enemies around you. You need to kill a cumulative total of 20 enemies with the grenades themselves.

The grenades themselves will take around a third to a half of a regular enemy's health off, and obviously do much less damage to tougher enemies. As a result, the easiest way to get kills with this ability is to shoot up and weaken multiple enemies in a group (they tend to cluster together anyway) and then dash into them and quickly use the ability. The grenades should do plenty damage to kill at least three per usage.

As with other combat achievements, you could grind this in a single combat encounter by using the ability and getting kills, then reloading your checkpoint to repeat until you unlock this achievement.
Killer Friendship

15
Execute an Auto-Combo with Gamora.

Execute an Auto-Combo with Rocket.
Refer to Timber! (15G) for more information.
Timber!

15
Execute an Auto-Combo with Groot.
The game never explains what Auto-Combos are, but they're relatively simple: during combat, if you melee () attack an enemy the same time an ally melee attacks them, it will initiate an Auto-Combo with that ally. So for example, if you melee an enemy the same time that Gamora is hitting them with her sword, a very quick scene will play of the two of you attacking that enemy together.

So for all four of these achievements, you need to melee an enemy the same time as that ally. This is particularly easy to do with Drax and Gamora because they are entirely melee fighters. Simply follow them around and attack the same enemy they do. Groot sometimes hangs back and uses ranged attacks, and sometimes melees, so you'll need to pay attention to when he's using melee on an enemy and take that opportunity to melee them at the same time.

Rocket, on the other hand, is virtually entirely ranged attacks and rarely gets up close to enemies. Pay particular attention to Rocket during fights and take advantage of any time he is up close with enemies so you can unlock his respective Auto-Combo achievement. Since he tends to hang out on Groot's back, you first need him to get off Groot's back. This will happen automatically if an enemy hits them, but I also had some success with using some of Groot's abilities, which would sometimes force Rocket to jump off. Once Rocket is off, you need him near an enemy (because otherwise he will just hang back shooting his gun). There are two ways to do this: either stand right next to him and wait for enemies to come to you (since enemies will always gravitate toward you over your allies), or once you unlock the wind elemental ability, you can use it to pull an enemy toward you and Rocket. This stuns the enemy though and I never had success with it. Either way, once you get an enemy next to you and Rocket, hover over and be ready to melee as soon as Rocket stops shooting. This is definitely the toughest one and can be annoying, so make it a point to get this one out of the way as soon as possible.
Thoughtful Captain

15
Find half of the Guardian Collectibles.
Refer to Managerial Skills (30G) for more information.
Managerial Skills

30
Find all of the Guardian Collectibles for one Guardian.
There are 15 Guardian Collectibles in the game, scattered across Chapters 1 through 13. You do NOT need to collect all of them for any achievements, so don't fret if you miss any. You need to collect a total of 8 of them to unlock Thoughtful Captain (15G) and then all of a specific character's collectibles for this achievement.

Unfortunately, there is no obvious in-game way to see how many collectibles a specific Guardian has available, and the only way to see which ones you've found is to go into their bedrooms on your ship and look around for them. However, here is a quick breakdown of all of the collectibles and which chapter they're in.

Quill
- Ravager Comm Bracelet (Chapter 1)
- Chitauri Sear-Cuffs (Chapter 3)
- Galactic War Commendation (Chapter 7)

Gamora
- Assassin's Ring (Chapter 4)
- Collector's Emporium Doll (Chapter 6) (costs 2000 units and can potentially void you from Galactic Frugality (15G))
- Meditation Stone (Chapter 10)

Drax
- Drax's Rap Sheet (Chapter 7)
- Mourning Candle (Chapter 10)
- Xatar's Blade (Chapter 13)

Groot
- Broken Translation Device (Chapter 2)
- Cold Case File (Chapter 5)
- Deeproot Plant (Chapter 13)

Rocket
- Spinal Control Unit (Chapter 1)
- Deep Mine Device (Chapter 8)
- Glarnot Mask (Chapter 12)

As you can quickly see from this breakdown, if you follow along with the guide below, by Chapter 7 you will have collected all of Quill's Guardian Collectibles and will unlock this achievement. You will also have collected eight Guardian Collectibles by the end of Chapter 7 and will have unlocked Thoughtful Captain (15G).

WARNING: I highly recommend skipping the Collector's Emporium Doll in Chapter 6 in the guide below. It costs 2000 units, and you need to be sure you have enough units left to pay your fine to Nova Corps in Chapter 9 to unlock Galactic Frugality (15G). It's best to skip that collectible to be safe.

Once you've unlocked both this achievement and Thoughtful Captain (15G) (by the end of Chapter 7, if you follow along with the guide below), you can ignore all Guardian Collectibles for the remainder of the game, if you wish. There are no achievements related to collecting all of them, or any more beyond what you've collected for those two achievements.

The following video guide shows all Archives, Items, and Guardian Collectibles in the game in chronological order. NOTE that even though the choice you make in Chapter 3 significantly changes your path in Chapter 4, the Guardian Collectible is present in both instances in Chapter 4, but in different locations obviously. It isn't missable nor do you need to replay Chapters 3 and 4 to obtain it. Just watch the section of the video for the path you chose.

Find and equip one Outfit.
Refer to Fashion Passion (30G) for more information.

Note that if you buy the Deluxe Edition (or get bonus outfits from any other means), you can equip one of these bonus outfits right from the start of the game to unlock this achievement.
Fashion Passion

30
Find and equip all Outfits.
There are a total of 30 Outfits hidden throughout Chapters 1 through 14 that you must collect for this achievement. Note that, in addition to those 30, you will unlock five outfits automatically at the start of Chapter 14, and you will unlock another four outfits automatically after beating the game (Chapter 16). Those nine outfits also need to be equipped to unlock this achievement, meaning this achievement isn't obtainable until after you beat the game.

The following video shows the locations of all 30 outfits hidden around the chapters. NOTE that even though the choice you make in Chapter 3 significantly changes your path in Chapter 4, the outfits are present in both instances in Chapter 4, but in different locations obviously. They aren't missable nor do you need to replay Chapters 3 and 4 to obtain them. Just watch the section of the video for the path you chose.

After you complete the game and unlock your last outfits (assuming you followed the guide and your last outfits are the ones you unlocked after completing the game), reload any chapter through Chapter Select. Once loaded in, open up the Guardians menu, go to each Guardian's outfits with , and just scroll through every outfit and press on each to quickly equip them all. Once you've equipped them all, this achievement will unlock.

Collect 65 % of all Galactic Compendium entries of each category.
(2)
When you press and tab over to your Galactic Compendium, you will see it broken down into six categories: Characters, Factions, Creatures, Places, Items, and Archives. For this achievement, you must collect at least 65% of the entries in each of the six categories. A quick rundown of each of the six sections:
- Characters - All of these will unlock with natural story progression. No exploration or scanning with the visor is required
- Factions - Same as above
- Creatures - Same as above
- Places - Same as above
- Items - These come from a multiude of sources. Many are story related and will be obtained automatically, another chunk can be bought on Knowhere during Chapter 6, another big chunk comes from Guardian Collectibles (you need to collect the Guardian Collectible and then interact with it on your ship and use all dialogue options to unlock its entry in the Items category), and lastly a couple more come from specific dialogue choices. Since you will get many from the story progression, and since you'll be collecting many Guardian Collectibles for Managerial Skills (30G) and Thoughtful Captain (15G), as long as you interact with the Guardian Collectibles on the ship you will collect enough items that way
- Archives - These are pure collectibles littered around all of the various areas of the game, but remember you only need to find 65% of them not all of them
As you can see, Items and Archives are the only things we need to actually pay attention to and collect for this achievement. The video guide in Managerial Skills (30G) shows all Items and Archives in the game (and all Guardian Collectibles too) in chronological order. Please refer to it for finding these collectibles. However, a few important notes to add.

NOTE 1: The decision you make in Chapter 3 causes Chapter 4 to play out entirely differently, and the Archives are split depending on which choice you made (two are available on one path and two on the other). However, since you don't need all collectibles for any achievements, there is no need to replay Chapters 3 and 4 to get the Archives you missed.

NOTE 2: In Chapter 6 on Knowhere, there are many Items you can buy with your units. I highly recommend you only buy the first two (lottery ticket and force lock disabler) because they're the cheapest. It's very important you make sure you have enough units when you finish Chapter 6 that you can still afford to pay your Nova Corps fine for Galactic Frugality (15G). Worst case, don't buy anything on Knowhere if you aren't sure how many you need. There are enough Items in the game that the five in Knowhere won't mess up this achievement.

NOTE 3: If you follow the video guide in Managerial Skills (30G) for all Items and Archives, and interact with all Guardian Collectibles on your ship, you should unlock this achievement at the end of Chapter 11. Chapter 11 adds a bunch of Characters to your compendium, and for me, it pushed me over the 65% in that category to unlock this achievement. If your achievement doesn't unlock there, don't worry - continue on with the video guide and you should have plenty of Items and Archives left to collect.
Galactic Frugality

15
Pay your Nova Corps fine.
This is a multi step achievement that takes place over multiple chapters. Even though it isn't missable because of Chapter Select, you potentially will need to play through many consecutive chapters over again if you need to attempt this again via Chapter Select.

Chapter 2 - right at the start of this chapter, when talking with Nova Corps on your ship, you'll be given the option to hide the llama or crate of parts before they board your ship. If you hide the llama you'll get a 7000 unit fine, hide the parts you'll get an 8000 unit fine, or if you hide neither you'll get a 9000 unit fine for both. You'll get enough money in the next step no matter which option you choose.

Chapter 4 - during this chapter you will end up in a vault. During this point, you'll have the opportunity to steal as many units as possible from the vault. If you steal all available units (they glow yellow in your visor), you should be around 11,000 units when done with this chapter.

Chapter 6 - there are a ton of things to spend money on in Knowhere. You can spend money on some items or a Guardian Collectible if you want, but none is required for any achievements. Either way, just make sure you save enough for the fine payment later.

Chapter 9 - when you reach Xandar and pull up the panel to send a message to Worldmind, choose 'Past Crime,' then 'Pay A Fine.' After the lengthy conversation, choose to 'Confirm Payment.' This will finally unlock this achievement.

Win the bet against Rocket.
Chapter 1

Shortly into this chapter, Rocket will point out some hanging parasite pods, destroy them, and then challenge you to see who can destroy the most. You'll see a retro videogame style scoreboard come up on the top of the screen. From this point until around halfway through the chapter, you'll encounter many more of these parasite pods (roughly 40-50 total), and you'll need to destroy more of them than Rocket does in order to unlock this achievement.

While you may notice quite a few on your own, the easiest way to spot them is to use your visor () which highlights them yellow, making them stand out quite a bit from everything else. Also be aware that you can shoot them from virtually any distance so long as you can see them. You can essentially progress through the chapter with your visor on the entire time, only taking it off to actually shoot, and you should have no problems shooting more than Rocket.

The first main area with many of them is an outdoor open circular area with lots of little bridges in the middle. Rocket will destroy many during this section if you drop down right away with him, but if you hang back up top, you can "snipe" many of them before Rocket has a chance. Even if you jump down and Rocket pulls ahead, there are plenty more to take the lead after that area. It seems like that is the only area where Rocket aggressively attempts to shoot as many as possible. You'll encounter more as you progress, and Rocket won't shoot at them if they're farther away, allowing you to easily take the lead before the end. As a point of reference, I had over 30 points to Rocket's 18 or so by the time we finished.

Once you get to the end of your travels together outside in space, a cutscene will trigger and if your score is higher, you'll win the bet and unlock this achievement.

To escape the fog cave, simple don't press anything (don't choose any dialogue options). Note that, even though pressing is supposed to be the equivalent of keeping silent, this soft locked the game for me and forced me to load my last checkpoint. To be safe, just don't press anything.

Story-related; cannot be missed.

Towards the end of Chapter 1, you'll place the final thumper and a monster will be hiding in the dark around the room. Destroy all of the crates with your guns, then you'll be able to spot the red eyes in one of the dark corners. Look at it, hold and press to choose Groot to catch the monster, unlocking this achievement.

Defeat the Dweller-in-Darkness.
(1)
Story-related; cannot be missed.

At the end of Chapter 4 you will fight the Dweller-in-Darkness. This fight has two phases.

The first phase involves it using its tentacles to try to smash you, two at a time. Open fire on a tentacle to fill up its Stagger meter. Once full, it'll land on the ground and glow orange. Unload on it as much as possible to do damage to it now, and once its health is drained, press when prompted to chop off the tentacle. Repeat this process for the other three tentacles.

Once all four tentacles have been severed, you will have to deal with a nonstop huge swarm of regular enemies. They are infinite, so only kill them if you need health from them. The way to progress the fight is to keep an eye on edge of the arena nearest the monster, right in the middle. The monster will drop an object there, and if you're looking in its direction you'll get a prompt. Do so and Drax will pick it up and hurl it at the monster. You need to do this a total of three times (while dodging, fighting, and avoiding enemies all the while). After the third hit, the monster will come down and open up, at which point you'll get another prompt for Gamora to finish the fight.
Family Intervention

Defeat the Blood Brothers.
Story-related; cannot be missed.

You will fight the Blood Brothers at the end of Chapter 6.

Initially, they will both be invincible. Once they "kill" you (you can't beat them), you'll get a cutscene and see how to hurt them: separate them so their armor deactivates, then unload on them. There isn't really much you can do to actually separate them aside from staying away, letting them charge at you, and dodging continually so they charge to different places.

You don't actually need to drain both of their health bars. Once you do enough damage the fight automatically ends and this achievement unlocks.

Survive the manifestations of Thanos.

This fight takes places near the beginning of Chapter 11. You'll notice that every time you defeat Thanos, he splits into more versions of himself. To end the fight and unlock this achievement, simply let him kill you.
Foom's Doom

15
Defeat Fin Fang Foom.
Story-related; cannot be missed.

This fight will take place at the end of Chapter 13, and is a relatively simple fight since there are no other enemies except Fin Fang Foom.

He will do a number of different attacks, all of which are telegraphed with a red exclamation and are easily avoided. You can shoot at him now but you'll barely do any noticeable damage. After enough of his attacks he'll shoot a heat beam into the sky (shown by a cinematic the first time) and make ice chunks fall to the ground. Avoid them, and after around five seconds of dodging look toward Foom for a prompt to interrupt his attack and stagger him. He'll fall to the ground, and at this point unleash everything you have at him to do decent damage until he recovers. Repeat this process probably three more times to finish him off.
Faithless

15
Defeat Grand Unifier Raker.
Story-related; cannot be missed.

This fight takes place right at the start of Chapter 15 and is another pretty simple one since there are no other enemies. Raker tends to just hover and shoot from above, so his attacks are all easily avoided. Just be careful of when his projectiles rain down (stop targeting him and focus on the circles on the floor to dodge them) as they can do a ton of damage. Focus fire on him to remove his shield and stagger him, then open fire to damage him. He has three health bars so don't let up or slow down, and he should go down pretty easily.

Defeat The Magus.
Story-related; cannot be missed.

This fight is the entirety of Chapter 16. This fight is again simple but a bit different since you don't actually fight Magus at all. You'll fight a pretty large swarm of enemies (they aren't infinite), get a cutscene, and then repeat with another wave. Each time you have dialogue options, make the obvious choice to antagonize him. For the waves of enemies, they can be very overwhelming, especially the slugs that jump onto you and do massive damage before you can push them off. Groot will automatically revive you every couple minutes with his final ability, so don't bother using it, just let it trigger if you die. Between his ability recharging, you should be able to use a huddle to refill your health once too. Since there are no really strong enemies, just tons of regular ones, stick to ally abilities that hit as many as possible. Rocket's starting grenade is amazing for this, as it kills almost every enemy instantly and recharges very quickly.

After the second wave of enemies are defeated, you'll get a simple quick time event, and then this achievement will unlock.
