Colton White rides for revenge in GUN, the 2005 western Neversoft made and Activision published. The cube version is that open-country shooter, with horseback travel between duels, posses, and a town that remembers every slight.
Quickdraw standoffs punctuate the riding, and the story is a personal feud spread across a wide frontier rather than a corridor of missions. Colton's family history is the fuse; the country is the level select.
The cube disc does not swap the west for a smaller map. It is the same horseback revenge story the other consoles told that year.
