The newly released Left 4 Dead 2 demo omitted one major bit of fan service - the ability to play as ZOMBIES in versus mode. Fortunately for PC players, there's a hack to give you the full taste of the game before you buy. Visit www.l4dmods.com to download a plug-in and detailed instructions. If you join an existing game (no plug-in required), simply use the command "set_infected 1" to become undead in the game - unless the server has this blocked or you're designated as a survivor by the host. Your zombie fun is limited to 2v2 for now, but it'll keep you happy until the full game releases Nov. 17...
