Help do i still get Halo 3 achievements for co-op mode doing campaign?

[Kiks S]

Like my friend and i want to do co-op 2 player mode campaign
So i can get the achvments, but can i do it on 2 player mode or i have to do solo to get achvmnets?

ye, you can. You actually can get more cause then it gives you the chance to get the achievements such as an exterminator.

you can still get the achievements when you play co-op don't worry.

No you can still get all the achievements you need in co-op. but if your looking to get an achievement for beating the campaign make sure you do the whole campaign in either solo or co-op because one time i finished half on solo and the other on co-op but i didn't get the achievement for beating the game.
