UDK / Unreal Engine 3 documentation file

UT was designed as an arena FPS, with head-to-head multiplayer deathmatches being the primary focus of the game. The game's single-player campaign is essentially a series of arena matches played with bots. For team matches, bots are again used to fill the roles of the player's teammates. Even on dedicated multiplayer servers, bots are sometimes used to pad out teams that are short on players.
