Notes[edit | edit source]
- If Isaac gets Key Piece 1Combined with Key Piece 2, unlocks the golden gate in the starting room of The Chest and Dark Room to fight Mega Satan. and Key Piece 2Combined with Key Piece 1, unlocks the golden gate in the starting room of The Chest and Dark Room to fight Mega Satan., the key will open the golden gate to fight Mega Satan, but if Isaac uses Forget Me NowWhen activated, the level ends and is freshly regenerated with new rooms, monsters, and items. Disappears after use., the floor will reset and Isaac won't get both Key Pieces back, making it so that the golden gate won't open again.
