When a match ends, it takes a LONG time to restart a new match. So you and the other players just sit there waiting for the timer. I believe it's a minute or two, which doesn't seem like a long time, but if you've played other FPS games such as Counter-Strike: Source, Counter-Strike, Unreal Tournament 3, etc. that are heavily into multiplayer, matches restart in 20 seconds or less. So a minute or two is quite a wait.
Anyway, it has A LOT of potential, especially since not all the functions are unlocked in the demo. I could see this game being great; However, I didn't have much fun playing it, mainly due to the fact I only played 30 minutes worth of the game.
Another note I'd like to throw out there is I hate starting new and everyone else already has/bought better equipment, so they could kill you with a single shot, while it takes you a whole clip to kill them. Just saying.
