Considered by many to be the best free first-person shooter on the web, you have to so many things to do in this game.
Every server has it's own player tracker, so you start without a rank on every server, until you rank it up.
There are also mods on things like shrub servers, giving you awesome abilities.
Mainly, you get a few character classes to play as, each being vital to the objective. Instead of being a straight-up run-em 'n' gun-em shooter, you have to get tactical in this game.
You can also record videos, or "demos."
Try to find the mod True Combat: Elite. Although TC: E is less of a class-oriented shooter, it's still a blast to play. You die very quickly in TC: E, so you have to get more sneaky, like corner aiming, crouching, or aiming down the sights.
Google the stuff, pl0x. Truly, you need to get this if you haven't already got a game like Counter-Strike or something.
