This Ones for Jenkins! 10
Kill 50 Flood Combat Forms on the level “343 Guilty Spark” on Heroic difficulty or higher.

Co-Op attainable: Yes, but easier Solo
Dummy Controller: Yes

This one will come naturally as you progress through the level. Just make sure you kill everything and find a shotgun is quickly as possible. They'll start showing up a few rooms after the ambush and there will be one on top of the bloody crate you use to escape guaranteed.

It can be done in co-op mode, but after the first player gets his achievement I suggest they stop killing immediately so the other player will have enough to get his as well.

Escape the Forerunner Facility on the level “343 Guilty Spark” in under 21 minutes

Co-Op attainable: Yes
Dummy Controller: Yes

Assuming you don’t get turned around, this is a fairly short level. Coupling it with killing 50 combat forms will slow you down, but it’s definitely not impossible. The trickiest spot is one of the containment rooms. You’ll notice a crate covered in blood with a shotgun on top. Use this crate to jump up to the second floor since there is not an actual path up.) Otherwise this is very straightforward.

Note: When you come to a flickering broken bridge, it is possible to jump across if you time it perfectly/ This can shave a minute or two off of the clock as well.

That Just Happened 10
Complete the level “The Library” on Heroic or Legendary without dying

Co-Op attainable: Yes
Dummy Controller: No

This one is pretty self-explanatory. Just beat the level like you normally would, but don’t die at all in the process. Shotgun is your best friend, rocket flood are your worst enemy, and carrier forms will always sneak up behind you. Bandana skull will make this level much easier since you don't risk being ambushed while searching for more ammo. Your best bet is to simply hunker down in each portion of the level and just grenade and shotgun anything that comes at you from around a corner. When your radar is no longer red, move on to the next segment and repeat.

Note: The dummy controller trick will not work on this level. In Co-Op both players MUST survive.

Speed Reader 25
Complete the level “The Library” on Legendary in under 30 minutes

Co-Op attainable: Yes
Dummy Controller: Yes

Note: Reverting to the last checkpoint will put your time back to what it was when it saved, so dying has no effect on attaining this achievement in single player.

For most people, this is the equivalent of Reach’s Solo Legendary achievement. This is one of the two biggies that puts the list difficulty rating up for inexperienced players. If you’re lucky, you’ll get this in just a regular playthrough. If you’re familiar with Legendary in the Other Halo titles, you might be able to pull this off in 20 minutes or so. Again, always have a shotgun. I also recommend having the rocket launcher whenever possible. It’s good when they start to pile up. Your best bet is to find a good corner to put your back against and just keep your finger on the trigger. Bulk doors will slow you down automatically. If you don’t have a bulk door, you better be moving forward.

Assuming you don't die too often, having a dummy controller can be beneficial as long as you don't have to back-track too much. Otherwise you're probably better off just trying to solo the level for this achievement.

Note: Bandana skull will make this easier because Shotgun ammo can and probably will be scarce at times. The skull eliminates the need for that.

Look out for the little guys 10
Beat the level “Two Betrayals” on Heroic or Legendary without killing any grunts

Co-Op attainable: Yes
Dummy Controller: Yes

Don’t kill cannon fodder? That seems kinda redundant... Fortunately, the number of Grunts on this level is fairly limited. the real trick is to let the Flood and Covenant fight it out with each other, than pass through when the fighting has finally stopped. The flood will almost always beat the covenant or at least wipe out most of the grunts before they lose. Just skip past the rest in whatever vehicle you’re using.The majority of the grunts will be encountered within the first part of the level as you escape the pyramid. Once you get past the first core and inside on the bridge, the grunts are gone until you get close to the scene where you lost the tank in "Assault on the Control Room."

On Co-op, you can have one player kill the grunts while the other player hangs back to get that profile the achievement.

Leave it where it lay 25
Complete the level “Two Betrayals” on Legendary without picking up a new weapon

Co-Op attainable: Yes
Dummy Controller: Yes

This is another one of those good/bad situations. Good news is, you start with a shotgun. Flood problem solved. Bad news is there’s a severe shortage of ammo for the weapons in this level and shotguns really aren’t that great against the Covenant. Again, you want to let them two factions fight each other and you pick off stragglers whenever possible.)

On co-op, if one person dies, they will respawn with an AR instead of a shotgun. This will not void the achievement so long as you continue to not pickup weapons. (This is a good means of keeping your plasma pistol battery full for those pesky elites.)

Note: Bandana skull makes this easier as the Plasma Pistol is good for Elite Shields and shotguns are good for flood. Everything else just gets grenades.

Tying up loose ends 10
Kill every elite on the level “Keyes” on Heroic or Legendary

Co-Op attainable: Yes
Dummy Controller: Yes

Remember the last good new/bad news achievement I mentioned? This one is worse. Good news is, the Flood are kicking the Covenants ass. Patience and persistence and you can eliminate most of the Elites early on. Before re-entering the ship, just make sure that everything is dead down below just to be sure. Once on the ship, again, make sure everything is dead. After encountering the Proto-Gravemind (Keyes Blob) this is where the bad begins. All grunts and Elites will be Spec-Ops units. There are easily 20 or so Elites from this point up to the hangar bay. Make sure you explore every nook and cranny of the 3 floors in the Hangar bay to ensure you got everything. Enter the banshee and end the level to make the achievement pop.

Kill 100 Infection form flood on the level “Keyes” on Heroic or Legendary

Co-Op attainable: Yes
Dummy Controller: Yes

I’d be worried if you can’t get this one actually. Just shoot the little poppers. One pop will kill a few of them each time. They also rupture when they hit your shield. so getting 100 should be no problem by the end of the level.

Cheap Trick: While beneath the ship, you will come to a cliff-side where there will be hunters fighting Carrier flood forms. Don't drop down, but instead stay up top and the carriers continue to spawn. With the Bandanna skull, they will continue to spawn and you can just continue to grenade them until you get the achievement.
