Rocket Arena was originally developed for Quake and is now available for UT. It gives players one on one or team vs team action. Each player spawns outfitted with all ammo, armor and weapons, making it a game of pure weapon skill (as opposed to collecting/guarding powerups).
INCREDIBLE mod. As the text says, it provides a way to play the game the way it was MEANT to be played. 1-on-1 (or 2-on-2) matches, where the emphasis is on how good a player you are, not how well you can time the respawn loop for your favorite powerup. Now THIS is DeathMatch, folks! Well worth the download...
