About Threshold Sector

Threshold Sector is a stealth FPS set in a mysterious underground complex. You explore dark hallways and twisted rooms, gather loot and equipment, complete objectives, avoid traps and try to find a way out. Its levels are procedurally generated from handmade modules, so each run creates a different layout.

Survive the complex

Mutated creatures, strange anomalies and the facility itself threaten your survival. Random power outages, spreading toxic gas, unsettling semi-alive matter and disease-infected rooms are among the dangers. The complex is filled with traps, and mistakes can have severe consequences: it can hear the noise you make and respond to it.

Scavenge and prepare

Search the facility for weapons, attachments, equipment and other loot to help you survive the expedition and escape. If you die, you lose everything you are carrying. You can also improve your hideout to fight more effectively and increase your chances of survival.

Uncover the truth

You have no contact with the outside world and do not know where you are. The company you worked for has left you behind, and you must find out why, what is happening underground and how to escape.

Demo content

The demo contains one handmade level, a few weapons and most of the core systems. It focuses on testing the main mechanics and basic gameplay loop.
