Step 1: Campaign
The first thing you need to get out of the way (since it's all you can play at the moment), is at least the first section of the campaign. The premise of the campaign is basically the reverse of any traditional tower defense game, where you play the attackers invading and destroying the towers. Each of the campaign levels is relatively short and not too difficult aside from a few missions near the end of the campaign. As you progress through the campaign you will unlock the other game modes necessary for the other achievements, as well as get a good portion of the tower kills for Avenger.

Step 2: Baghdad Mayhem
While the unlocked modes don't need to be done in any order, this mode is unlocked about halfway through the campaign so it can be completed first. In order to win, you need to finish 10 waves of enemies and a generator, with each wave giving you 5 minutes to destroy the generator and activate the next wave. Enemies do not despawn between waves so you can get overrun if you don't stay on top of killing a majority of the enemies each wave. As you progress through the waves, the enemies that spawn will become more and more diverse, introducing the harder towers at the higher waves. A basic strategy of balancing your time and money with your number and type of units will make this mode go smoother, but overall it's not too difficult. Losing your whole convoy at any point means you have to start over.

Step 3: Tokyo Raid
This mode consists of 18 unique maps, or islands, that you must pass through by completing various objectives in each. Being smart about using your commander for a distraction and keeping your units healed will help a lot in the early waves, which in my opinion are the most annoying due to your limited number of units. Make sure you pay attention to the objective and the clock because losing in any of the waves means you start over from scratch.

Step 4: Baghdad Mayhem Rearmed
Just as the title states, it's the same as Baghdad Mayhem, but with more waves and more units. Units also appear sooner in the waves, meaning you have to start preparing for the deadlier towers early on. Utilizing hit and run tactics on the towers surrounding the generators, as you work your way to the generator itself, will give you both room to breathe when you make the assault on the generator, and also the cash you need to upgrade your units. This mode isn't all that much of a leap in difficulty from the regular version, in fact once you get to the last few waves your convoy will probably be steamrolling the enemies (unless you made a mistake). As with the other unlocked modes, if you lose everything, you start over from wave 1.

Step 5: Trials
Trials are a number of very minor missions, each with their own objective for you to accomplish. They are all really easy to just finish, without focusing on your score, aside from the last one which can be pretty tricky. Luckily, I included a brief strategy (well, rather wordy, as they are really simple) for each to help you out.

Step 6: Clean up
By now all you should have to finish is Avenger, and you should be - I would estimate - about halfway there depending on how successful you were with the unlockable modes. To make it fun, less pointless, etc, I would just recommend you go back and try to up your scores on the campaign/other missions, or just use the strategy listed for the achievement.

  • Complete Baghdad Mayhem

    The Baghdad Mayhem mode is unlocked after completing the Baghdad portion of the game, which comes to a conclusion at mission 7. The mission has a number of waves that you have to beat, with each wave spawning more enemies and a generator that you must destroy within the time limit to reach the next wave. Enemies don't despawn between waves, and you can end a wave with all of the enemies still spawned, however clearing the map as much as possible is generally a good idea. Rinse and repeat the generator destruction process for 10 waves and you win.

    To do this easily, I started off with a tank and bought a shield>tank>crawler>supply truck in that order, then upgraded the supply truck three times and upgraded the shields once each and continued upgrading everything else from there. Made the whole thing a joke with no losses and tons of excess abilities (30-40 repairs, for example).

    Note: At this point you will not have all vehicles unlocked, so finishing up the campaign prior to doing this on higher difficulties would be a good idea.

  • Complete Tokyo Raid

    Same deal as Baghdad Mayhem as far as unlocking it, except you need to finish the Tokyo portion of the game.
    Tokyo Raid consists of 18 islands, or "waves", that you need to pass through while accomplishing various tasks on each island. The enemy types scale faster than either Baghdad raid, but the enemies are generally more spread out .
    When it comes to strategy, doing what I recommended for Baghdad Mayhem rearmed works fine. All that really matters is that you pay attention to what the objective of the wave is and what your time limit is (if you have one), other than that it is all pretty simple.

  • Complete all Tactical Trials

    Complete each of the Tactical Trials, the first of which is unlocked after finishing the first level in Tokyo. Below you'll find my general strategies for quickly getting through the levels for the achievement. In most cases you won't be getting a ton of points, but points don't = achievements, do they!? The strategies work up to at least Advanced difficulty, but again, that doesn't matter for achievements either (nor does it impact the gameplay all that much in my opinion).

    Trial 1 - You need to destroy 4 generators, each of which is guarded by a different type of tower. The trial is pretty straightforward, and isn't too hard to accomplish using a tank-shield-tank formation with each upgraded accordingly. Be sure to use hit and run tactics on the enemies on the right side of the map so you take mostly shield damage, and do note that the bottom left enemies are scorchers, so don't take them head on.

    Trial 2 - Very simple, just make it to the end of the map without blowing up the mines. To do this, make a straight path to the end of the map and put two shields in your squad and upgrade each. You can probably do it with just one but two works no problem. Don't expect a high score using this method, but it's easy :P

    Trial 3 - For this one, you have a limited amount of starting cash and you cannot purchase units once you start the trial. Instead, you must pick units up along the way. I started out with a shield and a crawler and went pretty much straight through the map, picking up a Dragon, another shield, and two tanks along the way. You start off with only one of each ability, so you will need a lot of firepower to get through the last portion of map as there are a ton of towers and the forced-direction areas can be tricky. Once you reach the wall of towers, you have to go down, then all the way back up and then all the way back down to the center of the map to avoid getting toasted by either of the scorchers. Overall not too bad once you get a feel for the last minute or two of the trial.

    Trial 4 - What may at first seem like a difficult concept, is actually pretty simple. Instead of the orbital laser working like it did in one of the later levels of the campaign, only one laser can be active at a time. That means, as soon as you cross into a red circle, that laser will be activated and you are free to move through the now grayed out circles. The best part about the orbital laser is the fact that it also destroys the towers! That means, the best way to handle this map is to move from generator to generator by first crossing into Tower-occupied red circles and moving out for a period of time while the laser hones in on, and destroys everything in the circle, clearing the way for you. Properly moving in and out of the lasers to have them do all of the dirty work for you will leave little room for error and death brought on by the towers, making this a pretty simple trial as long as you have at least one vehicle that can attack (I went with my usual tank-shield-tank setup).

    Trial 5 - In this scenario, you need to make it across the map without the luxury of gaining abilities for defeating towers. So what does that mean? Start off with shield-shield-APC and go straight through the map, and above the scorcher at the far end. While the map is just starting off, move your commander all the way right on the map to the scorcher that is facing way you're coming from and use both air strikes on it to get it out of the way. Once your convoy reaches the Carusaurum, add either a couple of tanks or a couple of shields to the front of you convoy and at least one of you group should make it to the exit just fine.

    Trial 6

    • Upgrade your first Crawler once, and the Supply truck twice so that it starts working toward a decoy. Keep the formation you start with for now.
    • Make your path down the second turn (i.e. the first turn that goes downward), then follow the bend and straight up past the top tower and then to the right of the right-most tower.
    • Try to distract the towers to keep your unit damage down. How well this works is pretty random since you can't control when and where enemies, or your own units, will fire, so you may have to start over a few times to make sure your squad is in decent shape.
    • Go straight through the path ahead, keeping the loop at the end that the game has already mapped for you. 
    • Move your Crawlers to the front of the line and make sure both have 2 stars.
    • As you pass through the row of behemoths, use all three repair abilities that you've gained so far and do your utmost to keep everything alive until the last two behemoths and the two regular towers. This part is also pretty random; you never know when and where units will be hurt so you may end up having units that are too healthy at the end, but you couldn't have ignored healing them either since then you wouldn't have had enough firepower. It's random and not entirely up to you, which is part of why this challenge is so annoying. 
    • Allow these last four towers to kill your Crawlers. 
    • Keep your squad in the loop mentioned above as you go left and use your aistrikes to blow up the mine, which in turn will blow up the other towers surrounding it.
    • If you have Crawlers still alive after the behemoth corridor, go downward past the two lone towers there and try to get the Crawlers destroyed there.
    • Keep going along the upper path and then steer sharply upwards through the regular tower corridor there. This is where you need to have your Crawlers and tanks die off. If your tank is at full health when you turn the corner into the tower corridor, you can pop a repair right as it passes the first tower and that will create a pretty perfect situation where all enemy towers are killed but your tank goes down as well. 
    • At this point, you should have a boatload of abilities, but only the APC and the Supply tank left. 
    • Run down to the two electical towers and use two of your airstrikes to take them out. 
    • Map the straight path to the end of the level and hold RT. 
    • The Scorcher didn't activate at all for me when I did this, but if it does for you, you should have 4 smoke screens which is way more than you'd ever need to get past it. The other two towers at the end don't do crap in this level, they just stand there looking at you.
  • Complete Baghdad Mayhem Rearmed

    This mode is unlocked upon completion of the game and can be found under Baghdad Mayhem in the main menu screen. It's basically the same deal as the regular version, with 8 additional waves, thus introducing all of the enemy towers.

    As far as a strategy goes, following my basic guidelines for the regular Baghdad Mayhem for the first 10 waves is a good idea, after that I recommend switching at least one of the two tanks to a Dragon and upgrade that. Also, now that the last few waves have the towers that repair dead towers (Energizers), make sure you run ahead of your convoy and use an air strike on those towers to make your life much easier.

  • Use 4 different abilities simultaneously

    You will unlock your 4th ability, the air strike, in mission 8. Once you have received that, simply wait until you have at least 1 of each ability and then use them all at once via the  +  in each direction.

    The easiest way to get the achievement done is to just pop all 4 abilities in sequence one right after the other; Smoke > Decoy > Repair > Air Strike in that order, running around between each of them to actually utilize them may take too much time since all 4 need to be up at the same time. 

  • Collect 14 Carusaurum caches

    You will start seeing Carusaurum caches on level 3 - Carusaurum, which you can actually get this achievement on too. The caches are distinctly marked on your tactical screen as glowing triangular objects scattered across the map.

    Simply set a path that brings your units (since you "collect" the caches by having your vehicles shoot them) by 14+ of these caches and you're golden. Carusaurum = money so if you don't get 14 caches ever, you're doing it wrong.

  • Use one Smoke Screen ability to protect 6 units

    You will unlock the Smoke Screen ability on level 3. After unlocking it, reach a point in the game where you have 6 units in your convoy and use the Smoke Screen ( and then left + ) once your convoy reaches a corner so each of the units fits into the initial circle. Simply having all six cross through the smoke screen at some point won't work. I unlocked this on the first corner in mission 8, but any time after unlocking the smoke screen and getting enough money for 6 units will work.

  • Fully upgrade a unit

    Each unit can be upgraded a total of three times, for a price that increases each time that unit is upgraded. The cheapest unit to upgrade, by far, is the Supply Unit you will unlock at the very end of the campaign, so don't worry about it before that point.

  • Collect 20 abilities

    You just need to gather up 20 of the abilities dropped by your friendly airplanes. You can get this on the second mission if you gather up every repair ability that drops. You will usually see or hear the planes when they fly over for a supply drop, and you can also see the abilities on your tactical screen (  ).

  • Destroy 10 Towers

    Destroy any 10 Towers. You should have this within a couple of minutes into the game.
