Here are some cheats and tips for the game Strider.
Three continues:
Press A, C, B, C, A, Start
at the opening screen.
Constant robots:
Collect two robots and find a container with a robo-panther.
Open the container, but do not touch it. Allow your character
to get hit and lose a robot. Touch the robo-panther to activate
it. After a short amount of time, the robo-panther will leave
the two robots with you. They will remain even after you lose
a life.
Secret room:
Move past the gorilla in level two to the section containing
spinning gears. Jump on one of the containers, then jump into
the rocks that are above. If your jump is timed correctly, you
will become caught in the rock and appear in a secret room. Keep
jumping until this occurs. Defeat the Phantom, then climb the
wall to the right to exit and continue normal game play.
