This game has proven to be a remarkable piece of entertainment, however, it lacks the necessary challenge to keep players on their toes. A higher difficulty mode would certainly spice things up. Fingers crossed that the developers take note and release a patch that addresses this issue.

It's worth noting, that despite the lack of challenge, the game's gore system is absolutely mind-blowing. The satisfaction of mowing down hordes of zombies is unmatched, making for an absolutely cathartic experience.
