A deep, detailed combat submarine simulator with a lo-fi aesthetic. Manage crew, nuclear reactor, radio, sonar, radar and power all while remaining undetected and completing the mission.
You are the captain. The reactor, the crew, the sensors, the weapons - every system on the boat is yours to command, and every mistake is yours to survive.
ABOUT THIS GAME
SubSurvival is a deep, real-time nuclear submarine simulator with a phosphor-green command interface. There are no cutscenes and no quick-time events - just you, a 100-metre steel tube, twelve crewmen doing their jobs, and a cold, hostile ocean full of things trying to kill you.
The whole boat is simulated. Trim the reactor rods against coolant temperature or SCRAM it and wait out the cooldown on battery. Manage the electrical bus - every pump, radar, and sonar draws kilowatts, and a dead battery means a black, deaf boat. Watch O2 and CO2. Fight fires and flooding compartment by compartment. Seal a section to save the ship - and whoever's inside it.
HUNT OR BE HUNTED
Realistic detection warfare: build sonar tracks from faint bearings to fire-control solutions, exploit the thermocline, go deep, go quiet
Full weapons suite: homing torpedoes, cruise missiles, nuclear missiles, noisemaker decoys, and SEA TALON anti-air missiles
Enemies that hunt back: frigates with helicopters and sonobuoy fields, attack subs that evade below your torpedoes' depth envelope, patrol aircraft, minefields
LIVING BOAT, LIVING CAMPAIGN
12 autonomous crewmen who stand watch, eat, sleep, fight fires and flooding, and die - manning matters
Scripted campaign plus endless procedural tasking: intercepts, strikes, convoy escorts, reconnaissance, joint operations
SURVIVE
Breakdowns strike without warning: pump trips, leaks, fires, radiation. Wear grinds down machinery unless your crew maintains it. Auto-pause catches disasters at high time compression - or turn it off and live dangerously.
The sea doesn't care about your mission. Bring your crew home.
