Co-Op gaming is usually an incredible experience. There's nothing quite like being in the moment, communicating with you teammates.
"I'm under fire, pinned down. "
Suddenly your comrades are busting through the door dropping tangos faster than a Christian Bale F*Bomb. It's a great feeling when it all comes together. But sometimes there's a problem. The problem with co-op can be the fact you are playing with real people, and sometimes, sometimes these people aren't always there.
"I'm pinned down and under fire" only garners a response of "Man I really could go for a sandwhich."
