About Sync Or Sink
You're trapped in an old Cold War submarine. Your only goal: survive. Complete urgent repairs, manage limited resources, and keep the systems running. You can’t see each other. One misstep, one wrong call, and it’s all over.
Use your voice. Trust your partner. And don't run out of time.You’ll never make it alone. Communicate through a crackling walkie-talkie. One speaks, the other listens - no exceptions. Relay codes, fix malfunctions, and guide each other through a maze of rust, steam, and shadows.
Forget clear sight. All you’ve got is each other’s voice. Keep it steady.Time is not your friend. Each second wasted brings your doom closer - flooding compartments, failing engines, failing minds. Complete your tasks quickly. Stay calm under pressure. And if you mess up?You’ll hear it. Feel it. Maybe even see it... before the ocean swallows you whole.

yeah don't ever ask for help from the terminal
Genuinely couldn't understand the point, or if I did, it was just running around fixing things until you win.
For a game centered around voice chat, you would think they would make it actually work and not be a broken mess. But then again, look at the developer's name. Can't recommend.
Terrible experience, the game is good and a good idea but everything is so buggy, you cant go to lobby you have to exit the game and after every game you still have to restart it to make the walkies work. There is no guide no nothing so when you get thrown youre ♥♥♥♥♥♥ and even after learning the game is so bugged that there's not even a point in playing this game. It was a good concept but it needs A LOT of work
can always count on low effort interactive to deliver a quality product in all seriousness, the voicechat was buggy, there was a incredible lack of settings, the game was very short, fps wasn't the greatest especially for a small submarine like that, and the events were a bit boring and easy. all things considered though, it's a free game.
The game is a little confusing at first, but you can figure it out after a try or two. The hardest part ends up being just reading the code for the diagnostics. Not too bad but very barebones as you can see that no review has over 2 hours of playtime. But hey, free is free so give it a shot.
