The sequel has now been released: Darkest Depths.
What else? Find out for yourself! Here's the story, too:
You assume the role of a victim of a boating accident a few years after a huge war. You wash up on an island, with a conveniently placed bunker from the war. You decide to use it as a shelter, but once you get on the elevator (Which strangely still has power), it breaks and you find not a place to sleep, but rather a place that you must struggle to escape from. What will you find in the bunker?
That's just a little vague background story for you ;) . WARNING: Some of the puzzles in this map may require some thought, but hopefully not too much. Thanks again for playing this, try and have fun! Also, be sure to inform me if you make a video.
Also: You must use the resource pack provided! Also, just a special note: The first generator is in the lava room, at the top (You must do some parkour-type stuff). This will make sense once you play.
