Six cave archetypes descend from a surface extraction buoy into narrow flooded passages, but most of the terrain remains invisible until a sonar pulse reveals nearby walls, air pockets, and relics for a few seconds. Each dive begins deep below the surface. You must collect every relic in the selected cave and then navigate back to the buoy, balancing the need to search against steadily falling oxygen. Glowing air pockets restore oxygen, while depth below 180 metres adds continuous pressure damage to the hull. Colliding with rock at high speed also damages the vessel, so moving quickly through newly revealed terrain creates a genuine risk. Cave generation is seeded and reachable objectives are verified from the spawn, giving each of the six named layouts a repeatable structure without relying on external assets or network data. Successful extraction awards a score based on relics, remaining oxygen, hull condition, and completion time.",[49,58,60],{"id":59},"how-to-play","How to Play",[54,62,63],{},"Steer with the Arrow keys or WASD. Hold and drag on the cave when using a pointer or touchscreen; the submarine accelerates toward the drag position and coasts when released. Press Space or tap Ping to emit sonar. A pulse has a short cooldown and normally consumes a small amount of oxygen, so repeated pings are not free. Gold squares are relics, green circles are air pockets, and the faint yellow beacon at the surface is the extraction buoy. Collect every displayed relic count, then return to the buoy. Press P to pause, and choose any of the six cave layouts before starting a new dive.",[49,65,67],{"id":66},"tips-strategy","Tips & Strategy",[54,69,70],{},"Use sonar before accelerating, not after a collision. A pulse reveals enough area to plan the next few turns, so coast through known straight passages and save the next ping for a bend or junction. Watch velocity as well as direction: reversing thrust takes time underwater, and entering a wall at full speed costs much more hull than a gentle scrape. Relics are placed in the deeper portion of the reachable cave, which means the efficient route usually collects them before committing to the long ascent. Treat air pockets as route anchors. If oxygen drops below roughly one third, detouring to a known pocket is safer than hoping the next pulse reveals another. Pressure damage makes lingering at maximum depth expensive, so make decisions quickly near the spawn and do detailed route planning higher in the cave. Once all relics are secured, stop exploring and follow the already revealed path toward the surface. The buoy remains faintly visible even outside sonar range, but walls do not, so continue pulsing during the final approach rather than steering directly through unseen rock.",[49,72,74],{"id":73},"what-makes-it-distinct","What Makes It Distinct",[54,76,77],{},"Deep Current does not hide the map merely for atmosphere. Temporary visibility connects navigation, oxygen cost, speed, and risk into one system. The best runs are not those with the most frantic movement; they are the dives that turn each sonar pulse into a clear route, preserve the hull through controlled steering, and surface with enough resources to convert exploration into a strong score.",{"title":79,"searchDepth":80,"depth":80,"links":81},"",2,[82,83,84,85],{"id":51,"depth":80,"text":52},{"id":59,"depth":80,"text":60},{"id":66,"depth":80,"text":67},{"id":73,"depth":80,"text":74},"md",null,{},true,"\u002Fgames\u002Fdeep-current",{"description":6},"games\u002Fdeep-current","ZQd9vBXhZeDNfEUIQSOgNr0PFB9YgzeSCMEfRQqjWSE",1784767263354]
