Read a short story in Warren's Creepy or Eerie in the mid 1970's. Can't remember name, artist, writer or issue.
Synopsis: A ragged man wakes up in mist, not knowing where he is or how he got there. He hears, then sees, a human torso/tracked chassis robot approach. After a brief conversation, they battle. The man lies down, fatally wounded. The robot produces a med-kit. The final panel has the man, alone and waking, not knowing where he is or how he got there.
