While gameplay is similar to Half-Life's in terms of health-and-armor systems and artificial intelligence, one major aspect of Gunman Chronicles is the ability to customize each weapon. Gunman Chronicles is a first-person shooter that requires the player to perform combat tasks and puzzle solving to advance through the game, much like its predecessor Half-Life.
Plans were drawn to release Gunman Chronicles on GameCube, but it was never released. After significant work and with some office space, funding, and added staff, it was released as a standalone game. The game was popular at the Half-Life Mod Expo in 1999, and Sierra approached Rewolf to make a retail version. Gunman Chronicles 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 or Half-Life: Gunman (previously Gunman: TC and simply Gunman) is a first-person shooter space western video game originally created as a mod by the now defunct Rewolf Software.
