On the final stage of the Halloween Hellrun you're likely to lose a run and potentially game over very easily. What you may not know is that you are NOT being chased and timed by the doomwall, it's tied to you. You can go as slow as you like or even backtrack and you will be safe, you can only be killed by touching dinos. So on harder runs where getting there takes at least 7 minutes and you only need to touch one dino to die it is usually way better to just slow down when you see a stego.
