Worth a rental.

User Rating: 7.8 | Gun X360
GUN was fun while it lasted but once you did everything you could do, it will just sit there and collect dust. GUN doesn't have much replay value either, sure it's fun to run around and shoot people...for about 5 minutes. It's way too easy and short. GUN tries to keep you playing by putting on side missions, but fails.
On the positive side GUN gives you a nice variety of weapons to use, and has decent graphics and controls. You also get a good sense of freedom riding around on a horse.
Overall GUN gets a 7.8 due to it's low replay value and length.
