A cave in the Atlantic Waters.
Underwater caves are located randomly throughout your map, and are able to be entered by steering your sub into the cave. Once inside you can disembark through the hatch located in your submarine. Caves are procedurally generated. Inside you'll find Enemies, treasure chests, upgrade boxes, barrels, and lots of gold!
Upgrade Crates
Crates are found at the end of every cave and will contain a random Upgrade. Rarely, a Hermit Crab will be hiding inside it and will attack the players once disturbed. There are 3 categories of upgrades:
Lootable Bodies
Lootable Bodies found in caves are deceased explorers carrying a random item. If the player is already carrying two items, they will drop the one they are currently holding in their hands to pick up the Body's item.
Treasure chests.
Treasure chests found in caves can contain different pickups.
- A pile of gold.
- A common cave enemy of the respective biome.
- Fuel.
Barrels
Barrels inside the caves can be destroyed and contain different pickups.
Rubble
Rubble is found inside caves and can be destroyed and contain different pickups or relics.
Structure
The Cave Generator at work
Caves are generated by the Cave Generator, which will determine the amount and location of items, Barrels and Treasure Chests and how the cave is structured. Sometimes, caves will have a top and bottom layer, the top one containing the Crate and being where the submarine "parks" and the bottom one containing additional loot. Both layers can generate different floors, up to a presumed maximum of 4. Caves have a much lower chance of producing long or second floor caves than small caves, with the probability increasing the deeper you go.
