Versus+Mode&Campaigns

Versus Mode is one of the many modes of the game, doesn't necessarily require XBOXlive, but it gives you a wider range of gameplay. All you need is a player for each team (The Infected team and the Survivors team). In this mode only, you can play as the infected, as mentioned, giving you the chance to be cunning and devious with your enemies. In the first left4dead, the only 3 infected you could play as were the Hunter, Smoker and Boomer, occasionally the Tank, but you don't have the power to choose the Tank at the beginning. Each Infected is picked at random for the player currently on the Infected Team. Once either the Survivors have gotten to a safe room, or the infected team has incaped or killed the survivors, the points for the survivors team is added up, taking away points for using a Defib unit. Then the teams switch, and this time the survivors team is now the infected and vice versa. In the second game, the new special infected are playable, but the old rules still apply, you can't choose and once your infected you are playing as dies, you will reappear as a different infected at random. At no time can you become the Witch or the Horde. The Tanks chances of taking you over is dependant on the level of difficulty.
