SSTR description

SSTR: Survive the Horrors of Horizon

SSTR is a thrilling single-player escape-room style puzzle game set aboard the abandoned colony ship, Horizon. You awaken from cryosleep to find yourself in a state of chaos, as the ship's AI, Sister, has turned rogue. Once designed to protect the colonists, Sister now hunts down survivors in the dark, twisted halls of the ship.

Your mission is clear: navigate through the eerie environment, solve mind-bending puzzles, and discover the truth about Sister and her tragic past. The ship is in lockdown, and you must find manual override keys to unlock doors and access Sister's command core. Along the way, you’ll encounter the haunting remnants of the crew—messages etched into walls and cryptic inscriptions that may be vital clues for escape.

Survival hinges on your ability to scavenge resources and construct automated defense turrets to fend off Sister's relentless drones. Each step you take pulls you deeper into the horror of Horizon, challenging your wit and resolve. Can you unravel the madness and shut down Sister before it's too late?
