If done correctly, there was an Uppercut that could knock an opponent straight up into the air. If done over and over, you can whittle away at an opponent's health until they died and they couldn't escape it. It was a guaranteed kill, and really nasty to pull off in two player Head to Head mode.
The large pits can be traversed using a jump followed by a kick (the jump kick vaults your robot forward). Useful if you do not want to rely on the Pneumatic Legs all the time.
Not too shabby at all! Only thing I could think of to improve is when you trap enemies duck and fire your lazer, you charge twice as fast and have no recoil from the shot.
You're supposed to get across the gap with a jump kick, but anyone playing for the first time would never know that so i feel it's just bad level design at the very beginning. No where else that i know of has that kind of gap so it should have occurred later if at all.
