The most noticeable differences between UltraQuake and traditional Quake is additional objectives and the way ammo, weapons, and health are treated. All UQ players always have all their weapons (3 each). They are powered by energy that continually regenerates if the player has most of his health.

Should a player die, he spends a few moments wandering the map in limbo while his spirit regenerates. Each team has its own distinct differences and advantages:

Red Brawns have a built in tolerance to lava and require less energy to enhance their weapons.

Blue Brawns can cloak themselves (by pressing 5) but take greater damage if harmed in that state.

Green Brawns have the greatest floating ability, able to hold themselves aloft even without feathers.
