While playing type "SWIFT". A cheat icon should appear in the upper left hand corner. Now use the following keys:
'E'-------------Replenish your life meter
'D'-----------Replenish robots life meter
'S'----Destroys all enemies on the screen
'H'-------------Displays game info in HEX
'R'--Replaces energy icon after picked up
'HELP'--------------Deactivates the cheat
The cursor keys can be used to move Strider anywhere on the current game map.
Press 'LEFT SHIFT' to pause the game, and keep pressing 'TAB' to simulate slow motion. To deactivate hold down 'LEFT SHIFT' and press 'TAB'. Let go of 'TAB' and then let go of the 'LEFT SHIFT'.
I couldn't get this next one to work with my version, but it was left in cause it might work on another version. During play press 'HELP', 'LEFT AMIGA', and '1' at the same time to activate the cheat. Press '1'-'5' to skip to the corresponing level.
