The cryptic Final Puzzle challenge in Resident Evil Requiem seems to have been fully solved, with video evidence of the method now circulating online.
Earlier today, Pokémon YouTuber Gengar Collects provided proof they were the first in the world to complete the Final Puzzle — but there was still confusion over how he’d done it, despite his attempts to try and help other fans.
Now, a repeatable method for finishing the puzzle has been published online — albeit only after datamining work was carried out to reveal the necessary requirements. The solution is bizarre, and there’s still discussion among fans now over why exactly it works this way. But first… here’s what you have to do.

Warning! Spoilers for Resident Evil Requiem follow:
In a video published to YouTube, Resident Evil fan Kyro says they and fellow player Rantsycancy “spent two days tirelessly working through” Requiem’s Final Puzzle challenge based on a “datamining background.”
Step one requires you to wait 15 minutes at the game’s meat processing plant, where a conveyor belt of bodies are dumped into… well, a meat processor. In the following meat grinder sequence, you then must ensure all zombies die to the grinder, rather than shooting them yourself. All of this is to ensure that enough zombies have been harvested here, something the game quietly counts in the background.
Next, head to the toilets in the restroom area and flush one eight times. This is all you reportedly need to do to spawn Marie’s Doll during the facility escape sequence — the same doll that Gengar Collects accurately reported finding and using to complete the puzzle himself (though he wasn’t sure what he’d done to make it spawn).
From here, the solution resolves as Gengar Collects previously stated. You’ll need to complete the game, start a new save, then have Marie’s Doll in your inventory when inputting the now infamous code sequence into the DNA sequencer machine that players previously worked out last week. And with all of that done, The Final Puzzle is finally complete.
Fans are still working to deduce why this process is the solution to the puzzle. There’s speculation about a note referencing Marie that mentions extracting “a 2.3 millilitre sample from the 524.3 litres of blood collected from 115 infected,” which may be the count of bodies (or bodies not wrapped up) on the conveyor belt. Why you then need to flush a toilet eight times, though, remains to be seen.
For now, however, Resident Evil Requiem’s biggest mystery does at least have a full working solution. Are you planning to give it a go yourself?
