Just got this game, any tips?
Avoid falling into using the p90 consistently, and until you learn how to spray properly, just use a 3 burst or 1 tap, don't fall back into using p90's or anything you can spray like a cigarette because you are getting killed alot. I think casual uses a matchmaking system but its open to anyone who can direct join the server (friends usually), so people will be better than you there, deathmatch is a good place to start.
Don't fall back onto using the p90
