Hint: More rage:
Hit a vending machine until the pop cans fall out. Stand over a can and press X to increase your rage meter.

Hint: Defeating the steel worker:
When facing the steel worker at end of level 1, do not let him hit you. Hit him a dozen times and he should fall down and disappear.

Hint: Completing level 2:
When you get to the end of level 2, get the shotgun and shoot one man two times. Then, send a grenade or two flying his way to finish him off. For the other three men, put as many shells as you can in them.
