Get out of the door
The hallway is called like that because it is formed like the letter U. You enter on the upper left end.
New get to and through the door on the upper right end.
Pick up the ammunition in the back end of the room. So, suprised?
Get back to the U-Hallway and open up the last remaining door.
Here you have to react fast as zombiedogs are after you. Run straight
on right into the next possible door.
Get into the foor that is (nearly) directly facing you.
Monica's Dance Studio
Here you can finally grab a map of the Hilltop Center and you can use a save point.
Get back into the Hallway
The room at the head of the hallway is not that interesting, as there are only a fat sack and 2 zombie
dogs in there and nothing useful. You better head into the room at the end of the hallway, as there
you can find 1 medkit and 1 ampoule inside a locker.
So get back into the hallway
which you ran and run to the staircase. The staircase has the word EXIT written above the door.
There you run into the 5. floor as all other doors are broken.
