UNDERTIDE

Something moves beneath the waves. In Undertide, each trip begins as a simple fishing expedition, but the sea never gives away its secrets for free. Take command of a small boat, explore murky waters, find fishing spots, and return to Grimhaven before the night takes its toll.

This is a mobile game of nautical exploration, fishing and atmospheric survival, created for those who like increasing tension, quick decisions and that feeling of being alone in the middle of the ocean. You sail, watch the weather, manage your cargo and decide how far it's worth going for a better catch.

The loop is direct and addictive: leave the port, navigate with simple controls, look for fishing areas, face the line minigame, collect fish, store your cargo and sell everything when you return. The more you risk, the greater the reward may be — but the sea becomes much less friendly when darkness comes.

At night, the game changes tone. The fog closes in, the flashlight light becomes essential and the level of dread begins to rise. Some captures seem off. Some shadows seem too close. Returning to port may be the safe choice, but continuing to sail may reveal more valuable fish and deeper secrets.

Use the money you earn to improve your vessel at the shipyard. Invest in an engine, flashlight, hull, hold, map, net and protection to support longer trips. Each upgrade helps you explore better, carry more fish, find opportunities, and resist the dangers of the sea for longer.

Undertide doesn't try to be just an ordinary fishing game. It mixes mobile adventure, nautical horror, progression through upgrades and arcade survival in quick matches, with a dark atmosphere and stylized 3D visuals. The focus is on tension, exploration and the constant desire to do just one more expedition.

You also have a mission log, cargo inventory, port store, rumors, minimap and enlarged map to better plan your trips. Grimhaven Harbor serves as a refuge, market and point of evolution, but the real story is in the waters around it.
