for a reboot of the Unreal Tournament and that the release of the Unreal Engine 4, made this the ideal time to do so. The development of the game officially began on May 8, the same day of the announcement. Unreal Tournament was developed using Unreal Engine 4 in the open in close collaboration between Epic Games and the community. Although an Unreal Engine 4 subscription is required to fully contribute (all the code is accessible in a GitHub repository), Unreal Tournament fans are still able to comment and share ideas on the company's forum. During a Twitch livestream held on July 24 the same year, art director Chris Perna showed off a fully rendered but unfinished level in the Unreal Engine editor and talked about the overall look he wanted. A video released five days later via Unreal Tournament'''s YouTube channel, shows early footage of the game, with the development team playing the first round of Team Deathmatch. It is also taken up by discussions of what the development team is working on. This includes adding in almost all of the weapons and more complex levels. On August 13, 2014, a playable pre-alpha build was released. Originally, the build was only available to UE4 subscribers but thanks to the way the game is being developed, an Unreal community member was able to compile Epic's prototypes and to release them to the public. According to the development community on the download page, it would be getting weekly updates. On September 5, Epic hosted an Unreal Tournament event, where several competitive players and enthusiasts from each generation of Unreal Tournament as well as some of the community contributors were invited to play the early prototype version of the game at Epic's headquarters in Cary, North Carolina. The event was meant for providing feedback on the gameplay. As part of the announcement that Unreal Engine 4 would be free, a new build of the game was showcased during the 2015 Game Developers Conference, offering its first high-textured map called Outpost 23, which is a new version of the level originally revealed in the game's first-in-engine flythrough in July 2014, a new customized Unreal Editor and new characters. Two of the original composers of the 1999 Unreal Tournament, Michiel van den Bos and Alexander Brandon, both expressed interest in returning to compose the soundtrack. The final patch for the game was released on
