Short and sweet version: Fatal Labyrinth is a rougelike for the Sega Genesis/Mega Drive that was available in Japan on Sega’s modem add-on service, and available in America/Europe as a cart.
Fatal Labyrinth is a part of the “Sonic Ultimate Genesis/Mega Drive Collection” for the Playstation 3 and X-box 360.
It features an easy in theory achievement/trophy of getting to the fifth floor. In practice: Unless you abuse the SHIT out of save-states (that weren’t available in the Genesis version), this is damn hard to do.
You want eating? You have it, automatically when you pick up food. Eat too much? You die. Eat too little? You don’t regen health fast enough, so you’ll die.
Gold? Bitch, you have gold! But it has no purpose other than paying for your funeral. (Yes, you heard me right) Sega even mentions this little factoid in their “Museum” section for the game in the Sonic Ultimate Genesis Collection.
It’s a basic “rougelike” in terms of games now a days. But it isn’t going to kick your ass with it’s wealth of options like Nethack. It does it in terms of making getting up it’s 30 levels hard.
Worth a try for everyone. Funny how someone that does mostly platforming games came together with someone that does RPG/Rougelike-s like this and executed it (for a 1991 game) well.
