Of course, it can't just be that easy. As with horror games there must be obstacles to overcome. Some of these are in the form of environmental obstructions (stomach bile, etc). Just as you've survived, so too have others - unfortunately they are not as friendly. Enemies in the form of mutated, partially-digested humans will attempt to stop you. These disgusting designs clearly evoke icky feelings in players which is great for a good horror experience."
