Today’s Fallout 4 video is sponsored by the letter E

Fallout 4 is back with another educational video, done in the style of a 1950s Army flick about venereal disease.

In the wasteland, you’re worried more about radiation than the clap, and today’s lesson covers the attribute that deals with that: Endurance. It’s probably the last attribute you want to put at 1 in order to get all those good, good crits with a 10 Luck (to be discussed later). You can be weaker than flat Pepsi, you can be dumber than a bag of hammers, you can be as charming as an eel — and many people in Boston are. But you have got to be durable out in the wasteland.

In the video Fallout fans will recognize staple foods like Sugar Bombs and CRAM, as well as human flesh, and nourishment is critical if you’re going to do Fallout 4 in Hardcore Mode like any self-respecting Fallout player should.

You can revisit the flicks on Strength and Perception. The next one will be on Charisma. Fallout 4 arrives Nov. 10 on PlayStation 4, Windows PC and Xbox One. For more, see our preview from QuakeCon.
