That works, Beed. I'm having a total blast with it. I beat Needle Man with Cutter Arm (I'm using Bass), but it was tricky and it took me two tries. That E-Tank sure helped. Saved at the start of Toad Man's level.
I like that berserker route you took for Bass, Mike. It makes taking down bigger enemies much better (the giant flying met things in MMSPNEE).
