Silent Hill 2 Remake received a 1.04 patch recently, which unfortunately caused a Labyrinth breaking bug for both PC and PS5 users.
Players who had their last save in the Labyrinth before the patch reported being unable to progress after reaching the rotating cube puzzle.
Bloober Team released a statement acknowledging the issue and providing a temporary workaround of using an earlier save from before entering the Labyrinth.
PC users can also apply a quick fix by downgrading to the pre-patch version.
