Gun casts players as gunslinger Colton White, a man seeking vengeance on the people who have wronged him. "The only thing left he can trust is his gun," reads a line from the game's description.
Gun was developed by Neversoft with a story written by The Mask of Zorro's Randall Jahnson. Similar to Red Dead Redemption, missions involve fighting on horseback, taking over trains, and collecting bounties, while you can also play poker and hunt buffalo.
The graphics of course look dated today, but it's remembered fondly for its gameplay, including a quickdraw feature that lets you slow down time while shooting.
"Despite a great presentation that'll likely give a very positive first impression [in 2005], Gun ultimately offers too little content for it to be a truly satisfying game," reviewer Greg Kasavin said at the time. "Most all of the right ingredients are here in some quantity. But the hastily delivered storyline (which, fittingly, concludes with an incredibly abrupt ending) and the lack of any real depth to the gameworld make Gun much better suited for some quick, fleeting thrills instead of for the long haul."
Here are Gun's minimum system requirements:
OS: Windows: XP / Vista / 7 / 8 / 10
Processor: 2.4 GHz processor
Memory: 1 GB RAM
Graphics: 3D graphics card compatible with DirectX 9.0c
