If anyones interested in a half-life mod this one is quite fun (min 4ppl par usual) the basic idea is you choose a team: Vampires or Slayers then choose from certain characters each with their own abilities/weapons.
You can download it from a link here:

Also you can check out some screenshots etc.
Good Gaming ppl
