DM-Fate

This arena was built to be small, fast, and unforgiving. Designed for one-on-one matches, it will be the final judge of its combatants' abilitys. Come... Look upon your fate.

Fate was designed expressly for 1v1 Deathmatch duels, though it has an interesting mechanic with three players as well.

The only real issue is that the bots don't know how to lift jump to the Rocket Launcher rooms, but this is downplayed by the fact that you can't realistically hide in those areas and still kill your opponent.
