About S.O.N.A.R. - Submarine Operators Not Actually Ready

About this game

S.O.N.A.R. is a 1–6 player online co-op submarine simulator where teamwork is essential, panic is inevitable, and sinking is always just one wrong button away. Coordinate with your crew, use sonar to detect threats, and operate a cutting-edge submarine through combat operations, stealth infiltrations, and treasure recovery missions. Repair catastrophic malfunctions, recalibrate complex systems, and desperately hope that the person sitting next to you isn't just randomly pressing buttons.

UNDERWATER MISSIONS

The oceans are under enemy control. Gather a team of highly trained specialists (or at least people who claim they know what they're doing) and complete dangerous missions beneath the waves.

- Locate hostile vessels with sonar and send them to the bottom of the sea. Preferably before they do the same to you.

- Protect valuable cargo ships. Because apparently the military couldn't find anyone else to babysit them.

- Hunt for treasures. Use sonar to search the ocean floor for lost riches, forgotten artifacts, and evidence of previous crews' poor decisions.

- Slip past enemy destroyers undetected. Stay quiet. Stay hidden. And whatever you do, don't sneeze.

COOPERATION

Up to four crew members must work together to manage nine critical stations, including navigation, diving, sonar, periscope operations, engineering, and damage control. Your sonar operator tracks contacts while the rest of the crew keeps the submarine alive. When the sub catches fire or starts taking on water from twelve different holes at once, communication is the only thing standing between you and becoming fish food.

Use proximity voice chat to:

- Shout urgent orders.

- Warn everyone about imminent disaster.

- Explain why the catastrophe is definitely someone else's fault.

And if a crewmate starts reading the manual during a torpedo attack, give ’em a friendly slap back to reality!

Nothing says "successful mission" quite like a victory dance while all hell breaks loose.

CUSTOMIZATION

In S.O.N.A.R. every character is unique. Choose from dozens of uniforms, hats, and questionable fashion choices. Customize your equipment before deployment and unlock new gear as you level up. If you're going to make terrible decisions underwater, you should at least look good doing it.

SURVIVAL

Machines aren't the only things that break down. Humans do too.

Manage your crew's food supplies, rest schedules, and overall well-being. Neglect them for too long and they'll become exhausted, seasick, delirious, or mysteriously incapable of following simple instructions.

Health Tip: You really, really don't want to be vomiting inside your diving helmet when it's your turn to load the torpedoes.

Trust us on this one.
