Valve was on hand at last night's EA festivities to give attendees a chance to check out zombie survival shooter Left 4 Dead. In the game you play as one of four characters co-oping through a city ravaged with a plague of zombies, trying to shoot, melee and run your way from safe room to safe room.
The game starts off with your and three other players on a roof top behind a locked door. A nearby table is stocked with a selection of weapons, ammo and health packs. In the map we played, the first room had molotov cocktails, submachine guns, pistols and shotguns. Each player can equip a health pack, molotov cocktail, handgun and primary weapon: I went with the submachine gun.
Staying true to the zombie formula, your ammo is very limited, so survival isn't as much about clearing a room as getting through it.
