Long Dives

Long Dives is an idle game set on the ocean floor. Starting with a Generator, a Drill and a Market in the sunlit Shallows, you build up power, minerals and biomass. Diving resets your base in exchange for pearls that make each run faster.

Explore the depths

Ten depths lie below the Shallows. The first are the Dark, the Cinders, the Fissure, the Hadal Zone and the Rift. Each Ascension opens one more depth beyond the Rift, continuing down to the Nadir.

Trade on the market

You trade resources on a live order book with candle charts, limit orders, whales and a trade history. Rule cards let you automate trades: choose a resource, set up to two conditions, then buy, sell or post a limit order. You can start from one of five presets. Delivery contracts let you race urgent orders and advance through six contract ranks.

Send out your sub

Voyages take your submarine along a map of stops, with routes you choose one stop at a time. Stops include Survey, Salvage, Cache, Hazard, Waypoint, Current and Shelter. Seven story charters present questions at sea: a safe answer earns a small payment, while a bold answer rolls the hazard odds for twice that. Your final answer determines the charter's perk. You can also follow six leads and open three side regions: Drowned Yard, Vent Gardens and The Eye.

Automate your base

The Procurement Daemon can buy buildings according to targets you set or choose the cheapest available building. Auto Helm selects your submarine's next stop, even while you are away, and Autolaunch sends it out again when it returns. You can research four tech trees: Production, Exchange, Logistics and Automation. After being away for up to 24 hours, you can collect what your base produced; upgrades raise this limit.

Reset and advance

Diving resets your base for pearls. Ascending resets your pearls for Rift Shards and opens depths beyond the Rift. Striking a Covenant resets your Ascensions for Sigils, which change the rules. Along the way, you can decode the Archive, tune in to the Signal and discover who is Reading.
