Stuck in an outpost deep in a sea of toxic fog, your crew has been decimated, you're cut off from the outside world, and oxygen is running out. Use limited bandwidth to coordinate unstable crewmates, conduct esoteric research that could change the world, and interpret strange signals from the deep.
Navigate the perilous depths of a sea shrouded in toxic fog as you command dwindling crew members, conduct risky research, and decode mysterious messages that may hold the key to your survival.
About this game
Arrowflight Station - a remote research facility in the depths of a sea of fog, built in the shadow of a massive exoskeleton. Only five crew members remain.
You were supposed to be evacuated weeks ago. Now your sanity and your supplies are running out, as a violent fog storm has cut off any contact to the outside world.
Coordinate a dwindling crew from a ramshackle comms room in order to survive, and choose what to prioritize in the face of complete disaster: your escape - or the scientific breakthrough you've been chasing your entire life.
FEATURES
Remote puzzle investigation
Take on the role of a radio operator. Gather clues and solve puzzles by interpreting research data and surveillance footage of your unsuspecting crew. Get claustrophobic in the confines of a tiny comms room.
Clarity as a resource
Make do with severely limited bandwidth. Decide what data you want to clear up every turn, and what secrets will remain unresolved. Remotely guide your driver through dangerous terrain.
A myriad of mysteries to uncover
Inhabit a remote outpost built in an uncanny, foggy wasteland. Find out what’s behind the giant exoskeleton you are researching. Figure out what your crewmates are hiding and watch them go at each other’s throats.
Hand-drawn, atmospheric visuals and haunting sound
Immerse yourself in a world brought to life with a unique mix of hand-drawn art, retro-futuristic digital interfaces and an ambient soundscape that deepens the tension.
Multiple endings
Decide who of the four other crew members to keep up with and which storylines to follow - several playthroughs are needed for the full picture. Heed the call of what lies beyond, and choose your legacy.
PART OF AN EXTENDED UNIVERSE
Deep Fog Signals is a short, standalone experience that precedes the timeline of Misgiven, offering a dark perspective on events that shaped its universe 20 years prior. Find out what it's like to be a scientist in the depths of the crater of Koriol, exploring an uncharted ocean of toxic fog - discovering hidden horrors and wonders alike.
