Unreal Tournament is a futuristic first-person shooter (FPS) video game co-developed by Epic Games and Digital Extremes. It was published in 1999 by GT Interactive. Retrospectively, the game has also been referred to as UT99 or UT Classic to differentiate it from its numbered sequels. The game is based on the same technology that powered Unreal, but the design of UT shifted the series' focus to competitive multiplayer action, a trend at the time: id Software's Quake III Arena was released only ten days later.

). It all began on December 2009 when two clans from spain decided to form a new clan (Paellas survivors!) and become stronger, with more players and activity. It's on June 2010 when a player who was on both teams (nimbleMinds and Paellas survivors!) proposed the union. The idea was liked on both sides, so "Paella survivors!" became the ut99 nimbleMinds squad.
