The player is a prisoner sentenced to death and exiled to the secluded Mount Grimrock for vile crimes he may or may not have committed. Unbeknownst to his captivators, the mountain is riddled with ancient tunnels and dungeons. The player's mission is to form a team and escape by descending through the mountain, level by level. During the journey the player encounters mysterious puzzles, deadly traps, ancient tombs and horrible monsters left behind by crumbled civilizations long perished now.

Almost Human's issued the following update:

We know you’re all anxious to hear about the release plans and as you probably already saw in the big poster above, we’re finally able to tell you something concrete: The PC version of Legend of Grimrock will be released in early April and we are going to start pre-orders a few weeks before launch. That said, we have signed NDAs so we are not allowed to tell the exact date and distribution platforms just yet but rest assured that everything is now in good hands.
