Xonotic

Xonotic is an FPS that's inspired by games such as Unreal Tournament or Quake. Set in futuristic arenas, you can play solo or as part of a multiplayer game. It features 16 game modes including the classic 'Deathmatch' and 'Capture the flag', but also some more original ones like 'Runmatch' and 'Freeze Tag'. Xonotic is characterized by some very nervous gameplay that will really put your reflexes to the test! Lots of weapons are available, and some flying vehicles complement the arsenal.
