W,A,S,D to move. SPACE to pick up weapons
W,A,S,D to move. O to kick. P to punch.
Arrow keys to shoot in eight directions.
In the overworld run into an enemy to initiate a fight.
Important: for the initial release; this game only gives you one life to make it Nintendo hard (but not really it's easier than that.)
I will, if i receive enough comments saying that the game is too hard, give the player three lives.
The game is completely possible, but i don't expect you to make it on your first try.
Too hard for you? Use the Konami code for a Beretta with 99 extra clips.
