SUBJUGATION

 In Subjugation you're sent deep under ground to a decrepit containment  chamber. In the center lies a horror unbeknownst to the world, but  always a threat to it. You must keep the systems supporting it running  to keep it stable. Giving it a consistent feed of oxygen, water, and  punishing it from it's anger is vital to keeping it content and  complacent with containment, and to avoid it reaching from the depths to  the surface.
