Compact House

Description
"Absolutely necessary! Upgrade them and you'll get more Coins."

- In-game description

The Compact House is a resource building that produces coins. Coins collected from the Compact House can be used to buy almost everything. They can be stored in the Star Base, with a capacity of 9,000 coins, but mainly Banks are used to store coins. The Compact Houses can be found under the Resources Tab in the Shop.

Tips:
 * Compact Houses generate Coins over time. When their internal storage has reached the maximum capacity, they will stop generating coins. The internal storage of Compact Houses increases as they are upgraded.
 * An upgraded Compact House generates more coins, due to a faster rate and more capacity, and it takes more time before it's full.
 * If your coins storage capacity is full, you will not be able to collect more Coins. You can increase your capacity by building and upgrading Banks.
 * A Star Base can store, no more no less, regardless of level.
 * Compact Houses will keep generating Coins when destroyed.
 * Compact Houses take more time and costs to upgrade to a next level compared to Mines.
 * High level Compact Houses have lots of health. Because of this, players will often line Compact Houses outside their base along with Mines, as to keep units with no target (no preference to attack defenses) occupied tearing them down.
