Edit: Just realized why. There even is a help page about it. Might be useful to change the big "paused" text when the game can't (or won't) actually pause
Pause menu doesn't actually pause the game. Had to leave the computer, so i paused but i kept hearing the sound of (no spoilers) "someone" knocking me out. When i came back, i was able to look around and move while i was in the pause menu
