First thing Ill say is I've yet to play as a mastermind. I always pick random and get survivor. That said I haven't had this much fun playing a game since left 4 dead 2. I love playing all the survivors because they are all unique and keep the game from getting stale. It's face paced and each round plays out uniquely. It's a must have for fans of that game and the resident evil series. They have a already added a new survivor and another update is scheduled for May. I can't wait.
Cons: There's a sound glitch that you need to restart the game to fix(has happened to me twice in over 48 hours of playing). The host is always the mastermind and sometimes this creates lag. Sometimes it's hard to target enemies on the ground with melee weapons.
