Here's a little idea I have for my crossover AU. The difficulty is based on who you play as. To unlock Hard, you must beat Normal, and so on. Based on the difficulty, the character's actions will change (especially for Nightguard mode).

Normal: Child Mode
-Lower HP, but friendlier

Hard: Adult Mode
-Regular HP, less friendly

Extreme: Nightguard Mode
-Regular HP & brutal, but access to resticted areas (eg. Backroom)
