UED is powered by the Lost Dice system, in which every roll you make means one die fewer in your reserves. The result is rising tension over the course of your mission, as you try to succeed and survive with dwindling resources.
You set out into the frozen wastelands with your team of Runners, with heated exploration suits and the best equipment your Haven can provide.

Wild animals, human Renegades, the robotic Invaders, the biting cold - all of these could kill you.

And Zion could be next.
