Submarine 250The submarine can discover underwater treasures. Look for dive locations on the map, and send the submarine on missions. Upgrade the submarine for deeper dives that yield greater rewards.

Summary

  • The Submarine is an aquatic support structure similar to the Gunboat and Landing Craft.
  • It can be sent on missions for deep sea treasure at dive locations (yellow buoys with red flags) to uncover large amounts of resources.
    • The deeper the treasure, the longer and costlier it is to dive. However, resources are significantly better as well.
  • Treasures can vary between Resources, Crystals, and Diamonds.
  • To uncover dive locations, a level 7 Radar is required
  • Over time, you will use up your dives, and your number of dive locations will diminish. However they will respawn.
    • Dive locations will not respawn until you have two or fewer on your map. The fewer dive locations you have on your map, the more likely it is that a new dive location will appear.
    • Every 13 hours and 17 minutes after you have two or less dive locations, your game will “roll the dice” to see if one of your dive locations will respawn. This chance is relatively low, however, and it may take several days or even weeks for a new dive location to appear if you are unlucky.

Upgrade Differences

  • Initially, the Submarine is a bright yellow marine craft with black highlights and windows, covered with metal plates. There is a large dome glass window at the front of the craft, and a smaller one on top. There is a hatch at the top, and silver rails on both sides, with a propeller on the back.
