Metro 20-2.5D: Underrail Alpha Available

I have to go That There London later today and I'll no doubt find myself being propelled through underground tunnels in a metal tube packed full of people. A terrible fate, I'm sure you'll agree, but at least the London Underground is not yet in a post-apocalyptic state. Underrail is an isometric RPG from a school so old that it might well be Plato's Academy. Actually, not that old, more like the mid-nineties, when Fallout was Ultima with guns instead of Skyrim with guns. The surface of the planet is covered in fire and sewage, or something, so everybody lives in underground railway stations, which is becoming an increasingly common solution to the occasional apocalypse. There's a new video below, a demo here and the alpha is available to those who pre-order.
