You should really get Gunz, it's all free too. Amazing, and the graphics and pretty good too!
It's like you make a sandwich:
piece of bread 1: Matrix
filling: ut2003 (or any of them)
filling 2: Golden Eye
piece of bread 2: sword play plus gun play
Makes the best sandwich ever made.
When I say Matrix, I mean you can do all sorts of cool junk, like run up walls, run on walls, do back flips and shoot someone. My favorite is stabbing my sword into a wall of a pit just before you would go all into and die, and have someone chase me, then they die too, but I live. And the level system ROCKS! And there are no in game weapons, just ammo and health. You buy all of your weapons from money gained from kills.
