A very short and simple level that starts out by giving you very little ammo and with a giant Shambler charging at you with plenty of other monsters behind. In-fighting during this early segment is recommended to prevent total loss of ammo. With most enemies alerted as soon as you leave the first room, the level actually gets progressively easier as you go. It also is made of two parts, one of metal and one of stone (the latter made to be the crypt portion).
