overall good
Good game. took a couple of attempts to master the tactics but once you get the hang it can be rather easy. The jackhammer automated shotgun is amazing and cut down zombies like flies; i found it better than the GAU-8 minigun but all of the automated shotguns seem a tad underpriced for their worth.
combining some of the elements from base defence style games would improve this game vastly, e.g. gunners or automated guns in the base to pick off those peky red zombies that get past without being noticed as the sheer volume of gore makes the red one's difficult to spot.
great game but with a little work it could be one of newgrounds top!!
