This gametype transforms UT into a top-down shooter. Move the mouse to control the crosshair. Your character will always point at it. The movement keys move in the cardinal directions. You cannot jump, but you can still dodge.
The objective is to survive against the horde of enemies for as long as you can. At first, the enemies simply charge at you with Impact Hammers. As time passes, the enemies will start using different weapons and some larger, stronger, faster "boss" characters will appear. Over time or when enemies are killed, various weapons and powerups will appear. These include most of UT's normal powerups, including new Speed Boots and Regeneration.
The game keeps track of the top 10 scorers on each map at each difficulty level.
