I loved it. The game was slow paced and you had to be careful not to die and lose all of your money. It was a nice touch to be able to keep what you had already bought after you die. The enemies came in crowds and made it a challenge, at least until you get dual shotguns and max out reload speed. Great game, keep it up.
So Addicting i could keep playing it all day, to bad i got work to do with my company. One thing i do say lower some of the bad guys health i am a pro at these kind of games and for some reason even I struggled passed wave 22.
