Misshitsu no Sacrifice (loosely Sacrifice in the Secret Room) takes place in a facility deep underground, known as the Foundation, where five girls are trapped.
The set up is as mysterious as the game. D3 Publisher pegs Misshitsu no Sacrifice’s genre as “trap adventure”, but gameplay details haven’t been released. All we have is this trailer, which introduces the characters.
Trap adventure made me think of Night Trap, but Misshitsu no Sacrifice could be a sci-fi visual novel. D3’s interpretation of adventure is different than ours. Vitamin Z is also classified as an adventure game.
