Needs alot of help. The shield is a decent idea. It need more guns and other items to drop from bad guys. Id also recommend a change of scenery more often per dead guys killed.
A good game. I do wish it had a cooler monster and some more objectives. I do like being an invulverable monster instead the quick to die "Rampage" monsters.
It has a bunch of potential. I wish more guns were accessible on level 1. I really wish level 2 had a change of scenery.
The controls are bit different but not horrible.
