Is there a money cheat on onslaught 2

Edit: There actually is one secret cheat to this game, but to do it it is very difficult. First you have to hold control and hit a b c while your hitting abc at the exact same moment you must hit 123 as well, then hit shift up down(arrow keys) left right. Space bar 3 times and hold alt. After completing this task you must find a way to hit f1-f7 find a friend to help and you will own this ultimate cheat. Have fun cheating!!! :)
