Very evil
This piece gives me a full feeling of the games anyways as you search the city for random useless items to help you escape the city before morning when the city will be destroyed with a sterile bomb to kill all zombies and restore them all to normal as well, very nice zombie piece.
The bass is kind of up there and gives a feeling of desperation as you search and scour the city for answers to who made the zombies appear and how to get rid of them at long last. The synth has an industrial feel to it which is also nice and it gives a feel of dread as if a zombie could pop out at you at any moment as well. The drums are also giving a fast feel as if you needed to escape quickly.
Overall, awesome zombie piece, just needs some zombie moans and yells. Excellent work.
