Gun is a surprisingly good game.
The graphics are done very nice with good environments, The people you'll see are nice done a long with all the animals that's in the game to. The sound is nice to will well voice acting animals sound realistic as well as the guns.
One of the things that I don't like about the game is it's length, the story line is really short even if you do all the side quest that's in it. You can free roam which you can mess around and have a little bit more fun which will keep you playing for a little bit longer. It's got some replay value in it I went back and playing it at least 3 times before I got bored of it.
Overall Gun is a really fun western game and like I said anyone who played and really liked Red Dead Revolver will also really like Gun. It doesn't cost that much anymore I thank you can get it for around 8 bucks, so that isn't a bad deal for a good game.
