Left 4 Dead 2, Killing Floor or Payday 2 would be my first choices.

Various game modes in Garry's Mod, if you're desperate maybe the spec ops or survival mini games on Call of Duty?

Trouble in Terrorist town a Youtube favourite lol

Or if you want proper games and not kiddy shooters - Ghost Recon Advanced Warfighter 2 or Future Soldier. Operation Flashpoint:Red River or OpFlashragon Rising all have multiple slot co-op in campaign mode

Been having alot of fun on Killing Floor.
