In this game, you can…
- detach a burning section of your submarine, then put the fire out and re-dock the module.
- befriend a diver in voice chat, steal his headset, cuff him, and leave him in the abyss while the sub can't hear him scream.
- load an explosive railgun shot that tears your own hull open and forces emergency rerouting to drain flooded compartments.
- get blasted across a two-story outpost when three monsters burst from a vent.
- go outside to repair hull damage, get ambushed in the airlock, and fight the intruder off with only a wrench and screwdriver.
- weld an airlock shut to contain an infection while people on the other side scream, then limp the ship back with two survivors.
- keep a dog-sized pet mantis shrimp in a ballast tank, and have it follow you out into the abyss when the sub breaks apart.
2Iron Lung - A short horror game where you pilot a tiny submarine through an ocean of blood on an alien moon.
Mar 9, 2022
In this game, you can…
- pilot a one-man sub with no window, navigating by coordinates, sensors, and sound through a blood ocean.
- take grainy black-and-white photos, wait for them to develop, and use them as your only way to see outside.
- watch the sub deteriorate mid-mission as it shakes, leaks, catches fire, and starts flooding while you're still trapped inside.
- creep up to walls until an alarm screams, then scrape and bump your way back out while lining up the next coordinate.
- sit blind inside the hull while hissing pipes, metal groans, and moving splashes circle you somewhere in the blood.
- hop between mission nodes to photograph points of interest, staying still just long enough to hear what's out there.
- reach the final node, take the last required photo, and trigger a big scare as the payoff to the whole run.
- read terminal fragments in the sub to piece together a setting where the stars vanished and humanity is scavenging what's left.
