This one is going to be controversial, because this map is not a dedicated singleplayer map: it’s co-op, for up to 7 players (odd number, but who am I to complain?). However, it can be played quite happily alone, and I do, with potentially shocking regularity. Why? Because it’s procedurally generated, that’s why! Every play-through is different!
So while this does not strictly qualify for the SPRPG Diaries by being a dedicated singleplayer map, it is a map that’s stayed with me and that occupies much more of my brain than it should. I think, therefore, it deserves some attention and discussion.
