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.
This demo version includes most of the game mechanics and the first game location.
Press Kit
Editor takes
“The ASGARD-04 setup is a lovely retro-cyberpunk nightmare, and the choice-driven story earns its atmosphere even if the demo only teases the sinister secret.”
“A tense hour-long demo fits a break session, but keyboard/controller-only input and no save mention make it a hard sell for quick commuter play.”
How to play
Move with keyboard or an Xbox controller, explore rooms, and search for passwords, hacking devices, or alternative routes through ventilation shafts. Combat is possible but ammo is very limited, so evading enemies or finding other solutions is often the better approach. Your inventory is limited, so you must decide what to carry.
Tips
- Conserve ammo aggressively; some enemies cannot be stopped by bullets alone, so avoid unnecessary fights.
- Search thoroughly for hidden passages and alternative routes before forcing locked doors.
- Hacking devices can bypass locked doors, but they take up inventory space — plan what to carry.
- Pay attention to the story and environment clues; choices you make can affect how the nightmare ends.
- When resources run low, retreating and exploring another path is often safer than pushing forward.
