Resident Evil Requiem has a final puzzle so devious that there's now an entire subreddit dedicated to figuring out exactly what it is.

Behind the horror and the action, the Resident Evil series is known for its puzzles. The Spencer Mansion featured in the original game is one big puzzle box, after all, and while these elements may have taken a bit of a back seat in the more action-focused entries like Resident Evil 5 and 6, these tricky challenges can be tougher than any of the monsters.

And Resident Evil Requiem has seemingly unearthed the scariest puzzle in series history – one that no one can seem to figure out.
