This is the next major update that the developers have been working on these past few months.
Highly likely things to come with the update: A tycoon revamp. This will make the main tycoon less long so it will not take too long to sail around each tycoon. A dock on the tycoon where ships will be and you can jump on and sail the high seas! There will be cannons, enemy ships, and of course many rewards and treasure to find!
Likely things but not confirmed: Bring your troops on your ship to an island to find NPCS and get special loot! Ocean PVP to fight other players.
Update is planned to come out before August! Prepare your troops, you may just soon be sailing the seas and looting the great island afar!
