Dead Rising is one of the funnest games out for the 360, but it's not without its flaws.
You find yourself as a photojournalist, Frank West, stuck in an apoclyptic, George A. Ramero inspired, zombie infested mall, and you have to survive 72 hours until a helicopter comes to save you. Yeah. It sounds awesome, doesn't it?
Unfortunately, Capcom made it a little more than frustrating to fulfill your zombie hunting desires.
The story missions can get downright absurd in the difficulty department, as the game's save file system is crap. You only get one save slot, and there are no autosaves. So if you die in a boss battle, you're forced to get thrown all the way back to the other end of the mall and try again.
Also, the AI teeters on the brink of being dumb as hell or _too_ smart. The survivors you have to escort to safety will usually go out of their way to fight a large crowd of zombies and then get eaten, and the enemy AI can be downright unfair. Kicking you while you're down is the term, I believe.
So, in conclusion, the game is pretty fun. You just have to endure some annoying glitches and poor design in places, but when you finally get that chainsaw, you'll be more than happy that Dead Rising is in your game collection.
