I heard there's a steroid easter egg. Maybe Batman will face a villain he cannot stop and then take the pills, get addicted etc. and have to kick 'em like in Batman: Venom. That'd be like a small section of the game obv.

The body I've lost... the comrades I've lost... won't stop hurting.
It's like they're all still there. You feel it too, don't you?
