Another interesting thing about Mr. X and why he always seems to be close by
He's moving at extremely high speeds through unloaded areas, and when he gets to an area that's loaded, he'll begin the "patrol" where he can hear you shoot and run.
Also best to kill as many zombies as you reliably can in the station. You don't wanna be caught in a hallway full of mobs while X is tryna give it to ya.
Are you sure this is true?
I've seen out of bounds camera footage of Mr X walking around at normal speed
And on top of that, sometimes he is scripted to warp to where you are if you get too far away at certain points.
It's actually possible to spawn two Mr X's at once if you take advantage of this
