Can't beat extreme. So far, I've died at 1233 kills (wave 127). At some point, my damage output just isn't enough, and my lazer rockets and other combos start failing.
Any tricks to it?
The only time I really needed the z and x buttons (that I remember) was level 13. You can roll around with the winch and get that magnet from underneath. Think I exploited a glitch. Also exploited another glitch in level 21 where you can "lose" some of the ingredients to the non-insertion point by putting the ingredients into the wall and releasing prematurely. Other than that, great game. Hard to use winch though.
