Notes: Damage halves after 1st attack with all weapons. Axel and Hammerhead do damage while being on top of enemies. Mr.Slam does more damage holding Machine Guns while doing special.

It's not 100% I did it by just looking at the screen. I did it on PS3 PS One classics version. Beware that sometimes damage is halved.
