Nanatsu no Hikan: Senritsu no Bishō

, also known as Seven Mansions, is a survival horror video game developed and published by Koei for the Sega Dreamcast. It was released on January 20, 2000, in Japan. An international release was planned, but cancelled. The game is a sequel to the 1996 Sony PlayStation and Sega Saturn game Nanatsu no Hikan.

Gameplay

The player can control one of two characters: Kei and Reina. The game can be played in either first person, third person, or fixed camera angle views. Kei's levels are more action based, while Reina's are more adventure-based.
The title was also the first survival horror game to feature a real-time cooperative mode; players could control two characters independently and simultaneously. This mode was distinct from the main single-player mode, featuring a unique arrangement of objectives, monsters and events.

Plot

Friends Kei and Reina land on a mysterious island and search for their friend Ernest. But along the way, they encounter many different monsters in the different mansions they discover. It's up to them to defeat these foes, find their friend, and understand the mysteries of the island.

Reception

After briefly playing the multi-player mode, IGN.com stated that Nanatsu no Hikan: Senritsu no Bishō "is worth a try by importers looking for something different."
