I will give u props on the level make up but there r so many flaws such as 1. U have to manually switch ur weapons when ur out of ammo 2. U have to kill a certain amount of ppl to get to the next level 3. I still dont know how many freaking guys u have to kill to get past the part past the zombies 4 Eniemies dont stop coming, if u have a kill limit to get to the next stage or part of the level atleast put a limit to the guys
