Includes: Base Game UnderRail - Expedition DLC UnderRail The game is set in a distant future, when 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 the Underrail as the violently struggle to survive in the harsh underground environment. UnderRail - Expedition DLC This DLC expands the base campaign with many new waterway maps that connect various harbors of the Underrail as well as adds a huge new region called the Black Sea, a massive underground body of water. Take a break from the usual metro-crawling to take a boat to this infamous place. There, among the old and mysterious ruins of an age long past, you’ll face the vicious fauna, hostile natives, cunning pirates, and something far more sinister than all of those. Your voyage through the vastness of the Black Sea will shed new light on the history of the world of Underrail and the forces that shaped it.
