the co-op missions I think you can just beat them with a buddy, but that would be really hard I had a hard time beating them with 8 people.
These multi-player achievements irritate the f*ck out of me. Most of them are just tedious and don't contribute to the game experience IMO.
So what is the secret?
They have Coop 1-1 and I have beaten the extermination co-op in the beach area (albeit solo). Should I have received an achievement for this, or do I have to beat several co-op games before the 1-1 kicks in?
