Half-Life: Vampire Slayer - Chapter VI
VampireSlayer is a modification to Half-Life by Valve Software. The basic premise was to pit two teams of players against one another, where one side (Vampires) have better physical attributes
(running, jumping, close attack) against the Slayers, who have weapons. The Vampire myth lends itself to other playability ideas, such as staking, drinking blood to recover health, etc. The myth also lends itself to interesting settings for maps. The game is played in rounds, once you are dead you must wait until the next round starts. This shouldn't be too long and there are 'observer camera' modes for you to follow the remaining action. Vampire Slayer comes with built in bots so you can play single player games offline too.
