This the best game ever oh and guys if you want an easy way to get to the maximum level, then READ THIS!!! Just simply go on options select Nightmare difficulty go on the level mazey and you will spawn at one of the entrys for the zombies and there will be 2 barrels, so let the zombies come out a bit and then fire at the barrel and then you unlocked tons of stuff, so then select shotgun and kill everything in sight, and just play on until you reach the maximum level!! + this comment if you are a good person and want to help other people!
