About Threshold Sector
WELCOME UNDERGROUND
Threshold sector is an athmospheric stealth FPS with procedurally generated levels.
Explore the dark hallways and twisted rooms of a mysterious complex, gather loot and equipment to improve your chances of survival, complete objectives, avoid traps and most importantly, find a way out.
FEATURES
- Explore a dark underground facility - Procedural generation with hand made modules will ensure you'll never play the same level twice.
- Expect the unexpected - Danger is behind every corner in the complex, expect things to go bad quickly. Very quickly.
- Scavenge to survive - Search every nook and cranny to find weapons, attachments, equipment and loot to survive the expedition and escape in one piece - dying means losing everything you're carrying with you.
- Thrive underground - Improve your hideout to fight more efficiently and survive more often, this is your home for now, make sure to take care of it.
Survive the facility
Everything down here wants you dead. From mutated creatures to weird anomalies to the facility structure itself.
Experience random power outages, spreading toxic gas, unsettling semi-alive matter, disease infected rooms and much more... and much worse.
Stay on your toes
Death is always one false step away. The complex is flooded with traps and every wrong move could mean more than just a scratch: the whole facility can hear you and will get back at your noise and mistakes.
Find the truth
No contact with the outside world, noone is there for you and you don't even know where "there" is.
The company you worked for just left you here to rot. You need to find out why, what happens down here and how to get out.
DEMO VERSION
This demo version contains a single handmade level, a few weapons and most of the core systems. Think of it as a proof of concept, with a focus on testing the main mechanics and basic gameplay loop.
In the future a second demo will be released, with more features, systems and content, which will aim at finding a balance in the overall experience.
The last step in the development of Threshold Sector will be the full 1.0 release, with the complete range of features and content currently planned.
