Chernobyl Monsters

Getting increasingly excited about S.T.A.L.K.E.R.: Shadow of Chernobyl. Should be great when it finally arrives. One of my Russian mates tells me it is based on "true" stories of red eyed mutant monsters lurking near Chernobyl. Sort of like Yeti or Abominable Snowmen these things lurk inside the Zone attacking any looters wandering around breaking the security. Sounds a bit like Hills have Eyes to me.
