The title means "The house of seven mysteries – The Smile of shivering". A Biohazard (Resident Evil) clone game.
Translated from box back:
The door to a world of darkness, opened by the hands of two.
An organisation enshrouded in mystery. A hidden mad plan.
Each riddle leads to another.
A tale of love and shudders, told with beautiful and delicate graphics
A new style of adventure game – Pair combi system
Two players simultaneously control one main character each.
At times they walk together solving the riddles, at times they have to venture alone, hoping for the other's survival.
The game depends on the communication between the two!
To play two players, you need two Dreamcast controllers
