Army Of Darkness: Defense was recently released on those damned iOS devices, and so far the game is doing very well. It’s nearing 2000 customer ratings and still maintaining a 5 star rating. I only wish they would release it on Android, PSN, or XBLA so I could play it!
The game is out right now and you can download it for 99cents on the iPhone and iPhod Touch, or $2.99 on the iPad. But the price will soon be going up for the iPad version so get it while you can on the cheaps!
