Deep Sorrow is a horror/adventure game which leads you to a bunker and makes you feel desperate to get out.

An abandoned bunker, screams from the deep... While you seek your lost friend, you encounter some beings. Are they real or are they part of your imagination? Are you alone or are there anyone else? Are you insistent on finding your friend or will you take your first chance to escape? If you can escape...

Deep Sorrow is more of a adventure game than a horror game, though it has tension on its own way.
