Island Upgrades are permanent, island-wide improvements that you buy with money. Every island has ten upgrade types, each with a ladder of levels. All upgrades apply to the whole island and its members. They are opened with /is upgrades (alias /is upgrade). The Island Upgrades button in the island menu opens the same menu, but only for the island owner. Other members use the command.
How upgrades work#
- Every island starts at level 1 of every upgrade. Level 1 is free and is already active; the "cost to reach" column below starts at level 2.
- You always buy the next level only. You cannot skip levels.
- The cost is taken from the balance of the player who buys it, not from a shared island bank.
- The buyer needs the island permission to upgrade. By default that is Officer and above, and the island owner can change it, see Island Permissions.
- Upgrades are bought per island. If you own two islands, each has its own levels.
- If a level is bought but cannot be applied the payment is refunded. A repeated click on the same upgrade is not charged twice.
- A fully upgraded type says "There is no upgrade available!".
- If a member of your island holds a perk that grants a bigger island or more members than the upgrade, the larger value applies for those two upgrades.
The upgrade menu#
The Island Upgrades menu shows one button per upgrade type with your current value and, when you can buy a next level, the new value and its cost. Click a button to buy the next level. The back button returns to the island menu.

Tips#
- The cheap unlocks first: Waterless Crops and Lightless Crops are $250,000 each and remove the need to plan crop farms around water and light.
- The first levels of Sell Boost cost $250,000 and $1M and pay for themselves quickly if you sell often.
- Island Size is the most expensive ladder. The early levels (up to 250 x 250) cost $11.45M in total.
- Agree with your team on who buys upgrades, because the buyer pays and Officers and above can buy by default.
