Something like the co-op mode Spec Ops.
Goes like this:
4 teams of 2
Each have the same objective (kill a certain AI, steal a package etc.)
The team that completes the objective first gets a certain amount of XP
Then the game chooses another random objective (from a list)
Lives and stuff:
Lives: Unlimited
Time Limit: 5-10 mins
Able to kill enemy teams: Yes
Use your own classes: Yes
Maps: Small - Medium
AI Difficulty: Depends on the objective
Vehicles: NO!
Air Support/Helicopters: No (if they are in MW2)
UAV: Yes.
Ability to use heartbeat sensor on guns: Yes (if available on Multiplayer)
Available in Core And Hardcore Playlists
Name: Team Objective??
Thats my idea
