SHoizz Terror!

The SHoizz are coming! Can you defeat them all?!?! This is a very old game of mine that's around 4 years old, I have recently decided to come back to for a little while to fix things up, originally the game at some point was going to be changed into a generic zombie shooter game decided by an old friend of mine but I decided against that and retain the original concept of this game which is to.. Shoot SHoizz.. I have nothing against this particular person I just made this game for fun, I do not associate nor am I close to this person at all
