【Introduction】
The story is set in a world two years after a major bioterrorist attack that killed 170,000 people.
The story's protagonist, a journalist, miraculously survived that atrocity and has since devoted himself to solving the mystery of the attacks.
As our story begins, he receives a phone call. The caller tells him they wish to reveal the truth behind the virus used in the attacks two years ago...
Skeptical, he nevertheless follows the directions he has been given and finds himself arriving at a deserted mansion.
What he encounters there is beyond belief...

【Game Play】
The aim of the game is to use a range of weapons, including handguns, shotguns, and rocket launchers, to defeat terrifying monsters and escape from the mansion and laboratory.
This survival-action horror game is a classic FPS. The player is constantly forced to choose to either fight against their enemies or flee to safety. This management of the limited items available creates gameplay imbued with a sense of palpable tension.
The game also features multiple endings, meaning that the game's conclusion changes dramatically based on the player's actions.

【Audio】
The first game to feature the independently developed Enhanced Real Sound Effect (ERSE) audio system.
The atmosphere generated by the 3D audio effects creates a brand-new horror experience unlike anything seen before.
