Waited a year for this game in excitement. Highly disappointed in everything. 1st off the graphics are bad, I mean Sega genesis old. The controls are even worse. Can't aim down sight without it being overly sensitive or clunky slow. Player movements are the same. The zombies are too fast with the controls being so messed up. I tried calibration but like I said, too slow or too fast. If you like snap to kill games then you will probably love this, if you like to actually aim or run and gun then go elsewhere.
