Level Specific Kill Achievements
Wraith Killer - 5 points Killed all Wraiths in Uplift Reserve
There are 6 wraiths in total. You must play the whole level in 1 go and only the person who kills the wraiths will get the achievement. So if playing co-op make sure only one person kills all of them. You start with a Spartan laser so use this to kill most of them.
Both Tubes - 5 points
Got 10 Rocket kills on Kizingo Boulevard
This achievement is annoying because you only start out the level with 2 rockets. However, when you play co-op everyone starts out with 2 so you can swap weapons with your friends. Another way to get this is to shoot one rocket, then swap weapons with a team mate. Then kill them and take their weapon, it will usually have a bit more ammo in it.
Laser Blaster - 5 points
Got 10 Spartan Laser kills on ONI Alpha Site
Right at the beginning of the level you will have to set charges. Once done look back at where you started and be on the left side of the bridge (while facing backwards) when is says the bridge will blow, aim down to the right of the bridge and wait for the enemies to come. You should get 4-5 people with a shot, then pick your other shots wisely.
Dome Inspector - 5 points Got 15 headshot kills on NMPD HQ
Use the automag (pistol) and get as many headshot on the little enemies as you can, as it's a one shot kill on all difficulties. Then snipe the remainder of the enemies until you get 15 kills.
I Like Fire - 5 points
Killed 10 enemies with the Flamethrower on Data Hive
Once you have dropped down the second time and get to the icy area, go forwards and you will see that there is a fork, making you turn right. Instead go forward and behind a glass panel is a flamethrower. There are more than ten enemies in the next room. Credit goes to neurokaneda for the video.
Miscellaneous Achievements
These have to be done in either one level, or one game of firefight.
My Clothes! - 5 points
Plasma Pistol Overcharged and quickly killed 10 Brutes
You can do this easily to the enemies with shields. Just overcharge plasma pistol them and then when they are stunned, change weapons and kill them quickly. Very hard on legendary, and must be done in one level.
Pink and Deadly - 5 points
Got 10 Needler supercombine kills on any covenant
You can do this on any level, but must be 10 kills on 1 level. Just keep killing people with the Needler so that they explode.
Boom, Headshot - 5 points Got 10 automag headshot kills in any level
You can do this in any level because you always start out with an automag. Kill the small enemies (1 shot headshot)
Stunning! - 5 points Stunned a vehicle with an overcharged plasma pistol and quickly killed the driver
Self explanatory.
Ewww, Sticky - 5 points
Got 5 sticky grenade kills in any level
You can do this on any level, just press LB to cycle grenades. There are lots of grenades in every level available to pick up.
Dark Times - 5 points Killed 5 enemies while using VISR mode
Just press X and in this mode kill 5 people. You will probably spend most time in this mode anyway because the game is really dark.
Trading Down - 5 points
Traded weapons with a fellow character
Just go up to a team mate and trade weapons (LB)
Headcase - 5 points
Finished any level with at least one Skull activated
This is easy as you can use any skull, even the secondary skulls
Good Samaritan - 20 points
Killed no Engineers in the city at night during entire campaign, alone or with another ODST
Just don't kill any of the flying blob enemies until you reach the level Data Hive. This will unlock at the begging of that level. If you kill one you can reload a checkpoint and it will not count.
Naughty Naughty - 5 points Killed 10 Engineers in the city at night, alone or with another ODST.
You can do this after the game by loading up Mombasa Streets, then when going for all of the audio logs you will probably run into 10 engineers. However if not go back to the places you saw them before, because they respawn over time.
Firefight Achievements
Most of these are easily done on 2 player easy co-op. It will take around 1.5 - 2 hours but this way will basically ensure you get the achievements.
Also a tip for Firefight, if you have not got a full team always make sure somebody signs in a guest because you will get extra lives when you pass each round and they will come in handy for later levels.

Both players sign in with a guest on second controller when game starts both just use the guest controllers to play with and leave your main profile in safe area. Achievement will pop after the round for both players!
Vidmaster Challenges
Vidmaster Challenge: Endure - 25 points
In Firefight, on any mission, passed the 4th Set on 4-player Heroic LIVE co-op
Self explanatory, but very hard. Just get a good group together and figure out a good strategy.
Vidmaster Challenge: Déjà - 25 points
Completed Highway on 4-player Legendary LIVE co-op, with Iron, and no Hog or Scorpion
Credit goes to Porkchop for the video.
Vidmaster Challenge: Classic - 25 points
Finished any level solo on Legendary, on LIVE, with no shots fired or grenades thrown
You cannot press the right trigger throughout the whole level even in cars. It suggested to do the level Uplift Reserve and drive past everyone. To get Vidmaster Challenge Classic easy : When you start out with a Spartan Laser before you get into Warthog give the laser to one of your A.I. Teammates. They can fire with great accuracy and have infinite ammo and take out what you need to go on to next checkpoint.
Remember you cannot fire a single shot which even includes honking the horn in Warthog and powerslide with left trigger. Just go as fast as possible untill you come to a base in middle and you have to help comrades go to middle if you need to get new Warthog. Then go through to tunnel and hop into a Ghost it's faster, use boost now the whole way do not stop at anytime and do not use right trigger to fire. You can splatter as much as you want to the end and drop off the cliff. Achievement will not pop until next scene is over and you take control again. I did this first try, very easy in about 9 minutes!
Thanks to IRELAND NO 1 for this tip.
As another side note, when you get to the second area with the pond and the turrets, you can get out of your vehicle, just after passing the pond and walk up a ramp made of rocks, the jump is a bit tricky, but it will save you having to go past the turrets.
