Moons of Madness [official site] wants to be a lot of things: a Lovecraftian horror game set on Mars, a mature exploration of mental health issues and a hard sci-fi space simulator. Gulp. Its trailer certainly looks scary to me, although I’m the kind of person that can only play horror games in 15 minute bursts (I’ve been on Alien: Isolation for the last two months and still haven’t finished).
You’re astronaut Shane Newart, who is battling hallucinations to try and solve the supernatural goings-on on research station Trailblazer Alpha. From the looks of it, the gameplay will be a mixture of environmental puzzles (some of which will be very “technical”, apparently) and exploration/spooky segments.
