You play as a drug addict who for some reason is looking for some "medicine" in the abandoned hospital. Of course like other things in human lives, this is not gonna be easy, as creepy pumped inhabitant will chase you. But it looks like that he just wants to flex his chest muscles in front of you, rather than scare you. Nevertheless you still gonna die, if he gets to close to you.
The Hospital plays like many other horror games. You have classy spooks, which can be seen only through your smartphone. There is not much you can do to them, so better just avoid them. Look for drugs and try to escape.
