Good but you could fix some things; for starters the money collection. Even though i have it fully upgraded it still takes me time to go around collecting the money, which you have to do fast, and when you go fast it stays behind and you lose all of your hard earned cash.The worst is when you destroy the city and you dont evn get to collect it. Second, things go to fast. Between sending out zombies, hero's or the infection I lose track of what I am doing. Great game other than that! 4/5
