Just 15 minutes ago, my best hardcore character named “adventurer” expired due to his traitorous bear roommate. He liked staying away from towns because with 22hp on each limb, any form of combat is suicide. He mostly scavenged for food in the forest or whatever he came across, like that convenient LMOE shelter or that mine containing clean water. On the evening of Day 2, he found it was getting dark. Since the broken-down flatbed he used as a shelter last night was a good 20-30 map chunks away, he decided to go to the two-chunk cave to the south (containing a bear) and attempt to sleep without his bear roommate bothering him. He attempted twice, and the rock floor was, well, uncomfortable. So he tried to sleep next to a blood-splattered human corpse, and his bear roommate mauled him while he was trying to sleep.
