I have heard rumors of this secret (but unfinished) stage in the game, and have actually seen it in an online MK Fatality video (showing all Fatalities in the series from MK1-MK4). I've heard there's a secret way to get to it, but I have forgotten it and can't find it anywhere else. Can you guys help me? From what I remember, it has something to do with pressing a button on the second controller right as you defeat Shinnok at the top of the tower. (btw, the Skull Stage looks like a revamped Scorpion's lair, but without the skull pillars and floor textures. You're more inside an inverted skull with skull torches everywhere than anything.)

On a similar note, the other secret stage in MK4/Gold, the Top of the Endurance Tower, seemed to be... lacking something. Was this an unfinished level, as well, that was accidentally made available via kombat kode? (There's floor texturing, but everything else is black. No other towers, nothing.)
