About Subsurface
SUBSURFACE The deeper you go, the less likely you are to return. Descend into the unknown in Subsurface, a 1–4 player co-op underwater horror game where every dive could be your last. You and your crew are sent into abandoned underwater facilities to recover valuable scrap and meet an ever-growing quota. But you're not alone down there. Something lurks in the darkness, oxygen is running out, and not everyone is guaranteed to make it back. Work together, take risks, and get out before it's too late. 🌊 EXPLORE THE DEPTHS Venture into eerie underwater facilities filled with valuable loot, dark corridors, and deadly surprises. Each dive brings new opportunities to earn money, but staying too long could cost you everything. 👹 EIGHT TERRIFYING MONSTERS You're not alone beneath the surface. Encounter eight dangerous creatures, each with unique behaviors and ways of hunting. Learn their patterns, adapt your strategy, and pray you don't run into the wrong one. 🤝 SURVIVE WITH FRIENDS Team up with up to three friends or brave the depths alone. Communicate using proximity voice chat, stick together, and try not to panic when something starts chasing your crew. Just remember: nobody said you had to save your teammates. ⏱️ EVERY SECOND COUNTS Oxygen is limited, and the quota isn't going to meet itself. Decide whether to push deeper for more valuable scrap or return to safety with what you've collected. One greedy decision could turn a successful dive into a disaster. 🎰 RISK IT ALL Feeling lucky? Take your hard-earned loot to the roulette wheel for a chance to multiply your winnings. Walk away with more than you came with, or lose everything in seconds. 🎨 MAKE YOUR DIVER YOUR OWN Stand out from your crew with customizable diving suits, visors, and hats. Whether you're exploring the depths in professional diving gear or wearing something completely ridiculous, at least you'll look good doing it. 📋 DAILY MISSIONS Take on daily challenges to earn additional rewards while exploring, collecting loot, and completing dives. WILL YOU MAKE IT BACK TO THE SURFACE? The facilities are abandoned for a reason. The monsters are waiting. And your oxygen is running low. Grab your crew. Meet the quota. Survive the depths.Read more
