A playable demo of an alpha version of Underrail is now available on Indie DB, offering the chance to sample this old school turn-based isometric RPG in development at Stygian Software. This trailer has a look at the game, which was at one time known as Timelapse Vertigo, and here's a description: "The game is set in a distant future, when the life on the Earth’s surface has long since been made impossible and the remnants of humanity now dwell in the Underrail, a vast system of metro station-states that, it seems, are the last bastions of a fading race."
