This game is awesome!!! I like how we can upgrade our vehicle and start killing zombies :D
I don't think this games doesn't use any skill and I think you must use several skill to complete this game in a little day. You need to press "up" and "x" at the correct time , "up" while in round , "x" while in air and when you want to break trough crates. The upgrades is important too but you must do it wisely. Anyway this game is amazing I love it
really great game 5 stars!!
Awesome put make it longer
