Metal Sluggy Goodness
Eh, it's a pretty static, straight-forward game. Nothing wrong with that if it does it well though; zombie killing is always fun. Heck, I think the fact that it's extremely Metal Sluggy is a good thing.
Two complaints though. First is that the mines are fairly useless. The only time you're liable to want one out is when zombies are all around...at which point dropping one will get you killed. I suppose you could drop them out ahead of time, but that feels like a waste when you're trying to save up points for skills.
Second is the difference between increasing a weapons "Damage" versus its "Power". Namely, I have no idea what that difference is.
