SYSTEM INTRUDER is an atmospheric, first-person retro-cyberpunk horror game.
As Anna, a fragile young woman, you must survive the depths of a hostile skyscraper 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. Search for text logs, hack terminals, solve puzzles, and piece together the timeline of the catastrophe that consumed the ASGARD-04 complex.

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 chips 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 alone will determine how this nightmare ends for Anna.
