+I would give it a 9/10 only because the level system goes to only 50. If it would be higher and more skills in the next game i would give it 10/10.
P.S once you you get Zombie Run(where you can run like them) use it to your advantige not yourdisadvantige such as when you go into the garage use it then it your car breaks down to when ever you find a new shoping cart or someting.
BAH! stress reliever my ass! that damn game is so frustrating! dont get me wrong, I absolutely love it. those achievements suck severely. I had afriend on xbox live with all 1000. I made it to 700/1000 and gave up. I could have gotten some more but I gave up. the real mega blaster was worth those 3 or so hours mindlessly running over zombies in the tunnels though.
I think it is really fun game. It was fun playing for 14 hours straight for that single achievement. (you have to survive for 3 days straight in the game to get the megabuster thingy) my friends and I traded off and got food for each other. We also got a car and drove over 50,000 zombies for another achievement, best time ever spent trying to get achievements lol.
