Stupid dialogue and mindless gameplay. Perfect for the zombie theme!
The gameplay is similar to most shoot-em-ups of this mild genre, and is very very short for its money worth. After the 2 hour campaign (I took my time), there is little worth replaying except to just shoot anything that's moving in the survival mode. Even for a short game, I feel there could be more variety of weapons just for the sake of entertainment. For me, the off-beat humor is the selling point here, which is unfortunately over before you start to appreciate it.
