Gunman Chronicles is a 2000 first-person shooter game originally created as a mod by the now defunct Rewolf Software. It was originally a Quake deathmatch mod named Gunmanship 101, then it was moved to Quake II's engine before becoming a Half-Life mod. Gunman Chronicles was popular at the Half-Life Mod Expo in 1999, and Sierra approached Rewolf to make a retail version. After significant work, Rewolf was given some office space, funding and a mapper (Jeff Lane) by Valve Software to help complete the project, and it was released as a standalone game. Plans were drawn to release Gunman Chronicles on GameCube, but it was never released.
