Glitch: Stuck in corner
On the second level, enter the room with the shotgun
in it and two cases of ammunition. Once you enter through the
door, look to the left. You should see a pole a short distance
away from you. Go to it and go to the other side. Note: Do not
go behind; go in front of it. Then, look towards the corner. You
should see a shadow. Jump into it, then look towards the pole
and back up slightly. You should now be stuck. The only way you
can get out is to wait a short time. You should be able see under
the level for a moment. You can now walk around.
