Quake III : Team Arena

SUMMARY:
Team Arena will make your jaw drop, because it combines the best qualities of Q3A with a brand new GUI interface and a choice from totally whacked out variations of team based games. You can choose from game types like plain "capture the flag", and others. My favorite is "harvester", where you kill the enemies, and pick up skulls which you bring back to their base to score a "goal". The games are intensive, and the enemy AI is actually intelligent. When you play single player, you will be fooled into thinking that the AI actually knows what their doing LOL.
