Urban Terror is a freeware multiplayer first-person shooter video game developed by FrozenSand. Originally a total conversion of id Software's Quake III Arena, FrozenSand released Urban Terror as a free standalone game in 2007 utilizing ioquake3 as a game engine. While the game engine is licensed under the open source GPL, Urban Terror's game code is closed source and its assets are freeware but not open content.
Urban Terror started out in 1998 as a planned map pack for Quake III Arena, in which real world environments would be featured. It expanded from this idea to a full total conversion featuring realistic weapons and gameplay similar to Action Quake 2. Development group Silicon Ice Development was formed in spring 2000 and was made of several international developers, many whom were familiar with modifying Quake III Engine games; hence progress was made quickly. When its first version, beta 1.0, was released at QuakeCon 2000, Urban Terror was the realism mod with the most features and graphics completed.
On 25 December 2010 an Urban Terror HD Alpha 0.1 test was publicly released, featuring as notable change a new game engine (together with new weapons, maps and characters).
Urban Terror is billed by FrozenSand as a "Hollywood tactical shooter." It blends elements from games such as Quake III Arena, Unreal Tournament and Counter-Strike. The realism in the mod is introduced through a number of changes: The number of weapons and other gear that can be carried is limited. Damage is also more realistic than in Quake III Arena, based on dividing the player target into discrete areas.
