I am on chapter 12; Abducted and i cannot complete it because whenever i respawn the enemies are already aware of me. If i restart the complete chapter again, will i still gain the trophy for completing the game on crushing? I searched online and it is much easier to complete it using stealth.
As long as you start the chapter again on crushing it will still work. Not quite sure what part you're talking about because I don't remember that happening but yeah I would say chp 12 is probably the hardest one on crushing.
