Sorry but this Autoshoot feature makes it unplayable. I dont think it can deserves a rating yet.
The autoshooting makes the game unplayable, you die all the time because of it, and then loose all the money for upgrades. Also it's slow, boring and the ads are very annoying
good concept but shotting the zombies is so slow and hard to do
the auto slow my pc geting worst and i cant fix it
