The Underrail Website offers a new trailer from Underrail, an indie role-playing game of the old-school turn-based, isometric variety. For those who like what they see, the game is for sale in prerelease alpha form on Desura and GamersGate, and is the subject of a Steam Greenlight campaign. A playable alpha demo was released last summer, and this semi-recent developer blog explains what has changed since then, discussing modifying the game's economy for better balance. Here's an overview of Underrail:

Underrail is an old school turn-based isometric indie role playing game that focuses on exploration and combat. It's inspired by western RPG classics such as Fallout, Arcanum, Neverwinter Nights and System Shock 2.

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.
