Gun

Gun was released in 2005 for the PlayStation 2, Xbox, and Nintendo GameCube, alongside a later release for the Wii. The game was published by Activision and developed by Neversoft. It took advantage of the hardware of the era to render an expansive Western environment.

The game was developed by Neversoft, the studio famous for the massively popular Tony Hawk's Pro Skater series. Neversoft used their engine expertise to create a robust third-person shooter set in the American Old West. Gun was actually one of their first major attempts at a non-skating action title.

The game follows the story of Colton White, voiced by actor Thomas Jane, on a quest for revenge in the 1880s American frontier. The narrative involves a missing gold artifact and a massive conspiracy tied to a local mayor. It blends intense, linear action sequences with open-world exploration mechanics.

Yes, Gun was notable for featuring one of the earliest open-world environments in a Western-themed game, predating Red Dead Redemption by several years. Players could traverse the frontier on horseback, hunt wildlife, and take on various side missions. However, the main story missions were heavily guided third-person shooter sequences.
