I thought it would be one of those games where it's too easy it'll be over instantaneously. Boy, I was wrong. This game keeps you occupied so much, it's hard not to keep going after you get the badge.
This is one of the games that are easy to jump into and almost impossible to quit. I loved every single part of the game. However, as much as catchy the music/sound sounds, I feel like there should've been more soundtrack.
Really fun game. I had tons of fun with it and it kept me up for a while. The only thing that bugs me is when the survivors are one one side and my group of zombies are on the other. I want them to have the intelligence to find the last few survivors as well. Maybe that could be another upgrade?
