I saw the ad for it and was surprised it was actual content. i enjoyed it for 2 days, but then i already had everything in the game. (besides the p90, it requires 4 days played.) The game needs more content, such as more pistols, smgs, shotguns, and assault rifles. it would also be a nice feature if you added in more masks and if we could customize the entire zombie, ie. all of the zombies were in a robot costume. Another really good feature to add would to give the guns their own unique sound. So, really fun game for a couple of days, then it gets a little boring. it needs more content otherwise this will be a 5 star review.
note: i do see that the snipers are coming soon.
