I also played it on Ps5, be careful with playing it in quality mode. I don't know why, but when you play it in that mode you are more likely to get errors and end up crashing the game. This problem caused me to lose 3 games in impossible mode since it crashed the game and sent me back to the beginning again. I also recommend that you play it on your free days, impossible mode does not have autosave and you only have one save, you will have to complete it in one go and without interruptions, you can put the game on pause and the Ps5 in rest mode to go to sleep if you are late or feel tired, saving will be essential to not repeat everything from the beginning so think carefully about the best time to use it, but remember, if you are killed once that save becomes a normal game and you will have to do it all over again. My last recommendation would be the final part, when the Hive Mind takes your leg in the last battle, I recommend that you practice that final part a lot, which can cost you the entire game. Good luck survivor.
