# Island Upgrades

Spend your money to make your island bigger, busier and more crowded.

```
/ob upgrade
```

Four upgrades, each bought **one level at a time** with in-game money. Every level of an upgrade costs the same fixed price — there is no escalating cost, just a lot of levels.

## The four upgrades

| Upgrade              |      Starts at | Per level | Maximum | Cost per level |
| -------------------- | -------------: | --------: | ------: | -------------: |
| 🟡 **Hopper Limit**  |      5 hoppers |        +5 |      40 |    3 000 000 $ |
| 🟢 **Island Size**   |      10 blocks |       +15 |     250 |      500 000 $ |
| 🔴 **Spawner Limit** | 5 000 spawners |    +1 000 |  10 000 |   60 000 000 $ |
| 🔵 **Coop Members**  |      5 members |        +1 |      12 |   20 000 000 $ |

Each item in the menu shows your current value, your level, the next value, the cost and your balance. Click to buy. When an upgrade is finished it shows **✔ MAX LEVEL REACHED** and can no longer be clicked.

## What each one actually does

### 🟢 Island Size

Grows your island border, measured in blocks from the centre outward. Going from 10 to 250 turns a cramped starting platform into a genuinely large build area. At **500 000 $ per level**, this is by far the cheapest upgrade and usually the first one worth buying.

### 🟡 Hopper Limit

Caps how many hoppers can exist on your island at once. Try to place one past the cap and you get:

> **Limit »** Your island has reached its hopper limit (**5**). Upgrade it with `/ob upgrade`.

If you're building any kind of sorting or auto-collection system, this is the upgrade that unblocks you.

### 🔴 Spawner Limit

Same idea for spawners. The starting allowance of 5 000 is already generous, which is why the upgrade is the most expensive on the list — it's meant for very late-game farms.

### 🔵 Coop Members

Raises how many people can be on your island alongside you, from 5 up to 12. This is the **only** thing that changes your co-op capacity — see [Co-op & Roles](/androlia/oneblock/coop-and-roles.md).

***

## Who can buy upgrades

The **island owner**, or a member whose role grants the right permission. If you're a member without it:

> **Upgrade »** Only the island owner (or an authorised member) can buy upgrades.

{% hint style="warning" %}
Upgrades are paid from your **wallet**, not from your [bank account](/androlia/economy-and-progression/bank.md). Withdraw what you need before opening the menu.
{% endhint %}

If the economy is temporarily unavailable, the menu tells you so and nothing is charged — just try again in a moment.
