Rekkr: Sunken Land

A retro FPS set in a faux norse-celtic fantasy world in the midst of a war with the dead. Grab an axe, get revenge. Returning from war, you find your home village destroyed by monsters and your friends and family murdered. A rampage for answers and revenge ensues, leading you from your quaint island-town to vast underground cities, capital districts, and into the dark corners of the otherworld. Finally your quest has you trekking through a lost magic-tech civilization to set things right - the Sunken Land.
