UnderRail (2015)

Underrail is an old school isometric turn-based RPG 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.
The player takes control of one of the denizens of such a station-state whose life is about to become all that much more interesting and dangerous, as our protagonist is caught midst the conflicting factions of Underrail as they violently struggle to survive in the harsh underground environment.
