Gun tells perhaps one of the best stories you can get out of a game like this.
In Gun you play as Colton White. You both are on a steamboat that carries some important artifact and you get to watch as the boat is attacked and sunk, and you are the only survivor. You then set out to find out who killed your father Ned. You learn of terrible plots and watch many friends die.
Graphically, they could have done better for a next-gen console. The voice-acting is outstanding and is definitely one of the best parts about this game. Every character is voiced very well.
The gameplay is extremely fun. The gunfights are fun and always exciting. The horseback gunfights are done extremely well also, and the controls are very easy to learn. However the game is over too soon. There are side-quests to do to boost your stats, but you don't really need to do them because there effects are subtle. There is a variety in the side-quests which is a good thing. Overall Gun isn't a game you should pay full price for. Its a good title with good strengths and it has its weaknesses, but it is definitely worth playing.
