Infact I actually just plugged in a 2nd controller, latched onto that player then it was easy.

While you may not shoot, you may die (and kill enemies by doing so).

Level 2 has no end of level boss so might be worth a try ...

[AeGRENADER]

try level 2 if you wanna try it yourself. There is no boss there. However coop is easier if you find 3 cool guys to game with. I logged on when game came out this morning and got all achs with same 3 guys : _)

Yeah lvl 2 but stick to the bottom of the screen for most of it if ur going solo, and just try and get pass those ships that fly in a wavy pattern.

heres what i did
just start a match single player and have a person join (second controller) and then attach the first player(the one you want to get the achievement) to the second player and play as the second player tell the end of the mission
Quite easy
First Level

yeah actually thats a good idea! but its nearly impossible doing it on your own you can bearly get all the enemys in level 1 with out others your laser its too crappy!

[II Devastate II]

you can have everyone on ur team if you do coop just shoot while you sit back and dont shoot at anything

[Covenant]

Worked. Easy as pie. [/gamercard]

[merciless tengo]

doing it by yourself is pretty hard with the sperm thingies, they chase you soo much and theres a whole swarm of them.

It is best to do it with 3 other people so they cover you while you dont fire.

I just attached to someone and piggybacked without shooting thru the entire level..........
