Hektor is a first-person psychological horror game set in a covert research facility buried beneath northern Greenland. You play as a former subject left in its dark corridors after years of torture and confinement, with only a lighter and flashlight to guide your attempt to escape. Its setting makes the search for a way out part of a story about confronting the psychosis produced by that captivity.
The layout itself is unstable: procedurally generated corridors can alter the route behind you or the path ahead, making familiar turns unreliable. Exploration involves piecing together cryptic clues and scavenging for pills to keep your psychosis from worsening, alongside other items that help advance toward escape. A monster pursues you, while other threats can alert it to your presence, adding danger to the effort to navigate and investigate.
Its central design combines exploration, uncertain navigation, resource gathering and evasion within an atmospheric military black site, where even the apparent route through the facility may change.
