I received this game on x-mas of 94, at first I couldn't figure it out. So I shelved it till later. After I picked it up again and played through it, I love this game now. Lots of text to read but for a sega game the story is interesting. Lots of confusing but not impossible puzzles, especially the one with the cat. Really, that puzzle was frustrating.

I found an invincibility glitch that isn't to hard to accomplish. The recharge stations, jump into them and back out before they charge you up. If you can get the charger to run without you inside, you become god.
The first level isn't the best way to start a game. I get X-men vibes when playing through this level, The other maps are better, once you find the transporter the game really gets interesting.
