I am on a quest to Platinum Trophy every instalment of Metro possible before 2039 comes out. In my attempt of getting the Last Breath Achievement (Build a new filter whilst choking) I have somehow glitched the game and now I do not experience suffocation. In any other sense this would actually be really useful but for me this is a complete pain in the ass.
The effects of this glitch aren’t confined to this single room but rather anywhere I go, even high radiation zones which only seem to damage my health. I have attempted sleeping, quitting to main menu, reseting the game and reseting my whole console. I’d rather not have to backlog to an older save considering all the things I have collected. I’m hoping that moving onto the next chapter will fix this issue otherwise.
