Killer's Game: Part II

Six young people meet up to participate in a game of Killer's Game, where one person is picked at random to be the "killer", and secretly go around "killing" the other players, who then try and deduct who the killer is. People soon turn up dead for real though, as a mysterious guy in a skull mask start picking off the players. Also the dead players from the first movie have come back as zombies for some reason.
