Tier 1 - Complete Game - 18,800
Was able to knock a thousand off my previous low score run. Found a couple of new tricks to save a couple hundred here and there.
I can now get through the first two missions without using anything other than basic 50-point punches, along with the occasional weapon. The trick is to figure out how to knock people over without using high scoring moves, such as uppercuts.
The biggest thing I do is use elbow punches on the tougher enemies. Abobo, Willy, Jimmy, everyone. Earn the move early, but not too early. There's an optimum time to get it.
