The build I saw featured evil armored dogs, some kind of weird demon things that spit acid, and other hellish beasties. The environments were all well detailed, if a little drab, and the weapons were certainly creative. I used a spinning-three-bladed melee weapon to make dog-food out of a few demons.

The alt-fire mode on all weapons (which Machineworks claims is a first on an iOS device), was also a cool bonus.

The current build looked a bit choppy with its 3D models, however, and the enemies were barely recognizable, other than to say they were ugly.

In order to fit massive levels with such high-end graphics on your iOS device, Machineworks will ship the game in installments. You download one level and one boss at time, rather than a complete game.

The tradeoff is that despite the game's high-end graphics, Machineworks claims it can run on virtually all iOS devices, "down to the first generation iPod touch."
