01Crew of Four
Take a station and stay there. Helm, sonar, tubes, and repairs each need a set of hands - and a level head.
DISPATCH
Below the ice, the maps stop mattering.
FULL METAL COFFIN drops one to four operators into a flooded labyrinth of caverns beneath Antarctica, sealed inside a submarine hull built from materials that shouldn't exist yet. Somewhere out in the dark, outposts are dug in - and waves of hostiles are already inbound.
Nobody topside is coming to help. Sonar and hydrophones are your only eyes down here. Every ping gives away a position - yours, or theirs. Every torpedo has to be built for the fight in front of you, not the one you already lost.
SYSTEMS ONLINE
Four stations. One hull. No backup.
02Sonar & Hydrophones
Passive listening and active sonar are how you see in a flooded cavern with the lights off. Ping wrong, and something pings back.
03Torpedo Workshop
Craft torpedo variants suited to the target ahead - the wrong warhead on the wrong hull is how a crew becomes a wreck.
04Coordinate or Sink
Nothing about this hull forgives a crew that doesn't talk. Plans get made before the shooting starts, not during.
