Youtuber T-Ronix has done some impressive things in the world of Fallout. He's completed Fallout 3 without healing himself once, and somehow he's even topped that in Fallout 4. Playing through Survival Mode (which essentially kills you in one hit) T-Ronix successfully completes the game without a true death. I say that as he did die one time after a glitch in the game caused him to die after touching a stationary car, so we can't count that.
