Okay so I've been doing it all right i believe, ive placed the doll I found in the secret room onto the chair and then tossed a grenade, then the stalkers appear, and then they catch fire and all die as they're supposed to. BUT RATMAN IS NO WHERE TO BE SEEN, THEY ALL DIE. Please help me man I just want to progress with these secrets n stuff and without Ratman I literally cant do that
