About the game
Explore the dark secrets of ASGARD-04 in an immersive retro-cyberpunk survival horror inspired by classic 3D games. Search for clues, solve puzzles, fight enemies, manage limited resources, and survive the horrors lurking within a mysterious research complex.
Original Steam description
This is an immersive, first-person survival horror game set in a dark retro-cyberpunk world.
Survive inside a hostile research complex and uncover the sinister secret behind your presence in this nightmare.
EXPLORE
Just a few hours ago, this place was full of life, and the employees had no idea this shift would be their last. Explore the rooms of ASGARD-04, uncover hidden passages, hack terminals, solve puzzles, and piece together the events that led to the catastrophe.
FIND YOUR WAY
Not every obstacle has a single solution. Search for passwords, use hacking devices to bypass locked doors, or discover alternative routes through ventilation shafts. Sometimes, the right path is the one you least expect.
FIGHT
The facility's automated systems have twisted the staff into horrific cybernetic monsters. Find weapons to fight back, but beware: ammo is always scarce, and some monstrosities cannot be stopped by bullets alone.
MANAGE RESOURCES
Medical supplies, ammunition, and hacking devices are in short supply, and your inventory space is strictly limited. You will constantly face a choice: what to take with you and what to leave behind.
MAKE YOUR CHOICE
This story has no single "right" ending. Your choices will determine how this nightmare ends.
