For players who are thinking about buying: co-op is invite only.
No Matchmaking in Co-Op
It seemed absurd at first and then I thought about it. I think the game would be really hard to play with randoms as i'm pretty certain everyone would have to have mics and communicate with each other. There are whole sections where you have to sync up shots with team mates. This would probably be really hard to implement.
No terrorist hunt, No awesome co-op missions, Just 50 waves of horde mode.
