This isn’t a survival map in the truest sense of the world, ie, as in something you could actually ever hope to survive. It’s more of a cage match that you’re destined to lose over and over and over again. I suppose its technically possible to win, and anyone who does ‘win’ is going to be filled with the sort of sense of achievement that used to only be possible when you climbed Mt Everest or similar. Think I’m overstating the difficulty of the Sphere? Think again.
