Quake III Arena: Eternal Arena Combat.
"When the dust, blood, and gibs settle, all warriors will have earned the right to battle again, providing further entertainment for the Vadrigar. But only the warrior who has fragged the most foes will be lauded as the winner. The victorious gladiator advances to a more challenging array of arenas, until, at last, he or she faces Xaero, Lord of the Final Arena."
