All of the videos can be found on http://bethesda.net/#en/events/game/fallout-4-special-video-series/2015/09/10/24. The Endurance video just came out! And here it is on https://www.youtube.com/watch?t=5&v=paYU1neP3xM, for anyone that's particular.
I'm a little bummed that Cannibalism is still on the perk chart instead of being reward through character actions; I was planning on filling out every perk in Endurance for my character, but I have no intention of ever being a cannibal. Regardless, it's not surprising.
What is surprising is the emphasis this video puts on food and water. Do you think Bethesda incorporated some kind of needs mechanic, like hardcoe mode in New Vegas?
