Just a heads up: To get a perfect you have to play EVERYTHING right that means to play ALL notes and ALL the lil hold thingies if u dont hold till the end BAM its gold lol
i found out that if u have alot of bullets and have a old glory, start shooting and drag ur mouse off the game area but keeping shooting then drag it back...congrats u now have a gun that shoots by itself
Oh and also do the steps i said earlier until until step4 (dont do step 4 -.-;) if u didnt see check the oldest comments.Anyways do that stuff and leave 1!!! UNO!!!!! zombie standing. Then Cover BOTH places where they come out.kill the last guy and stand in front of one spot where they come out. bringout ur rockt and hold space...you will be blowing up thousands of zombies. i did this and got x 999 =D O.o and whn u run outta ammo just go get the red pickups till u get the rocket one. Happy Killing!!! XD
