Glitches
The Mega Drive version has a game-breaking glitch that allows you to walk through virtually any wall in the game. With your back against the wall, run forward, and immediately turn around while tapping the run button (A). The animation for Conrad turning around should start earlier than it normally would. When done correctly, and assuming you have enough space to execute the glitch, Conrad will walk through the wall. Beware that some out of bounds areas in the first level Titan completely crash the game.
