The Statue of Maintenance
The Statue of Maintenance is a late-game structure that serves not only as a landmark, but also provides some Maintenance reduction for a symbolic Fuel Gas cost. It requires only 2 Fuel Gas per minute and also has an internal storage for 20 Fuel Gas that provides reserves for considerable amount of time in case the gas supply is out.
In the building window, the following text is shown:
Text on the plaque:
Life can be rough,
if you don't maintain your stuff.
And when things fail, just look -
missing entry in the service book!
Supporter Edition content
In the Supporter Edition, the statue can be upgraded into The Statue of Maintenance (Golden) version, unlocked by the same research. The upgrade costs 800 Gold and provides only cosmetic differences. While this version of the Statue cannot be selected from the menu, it can be built directly using the Clone tool. In this case, the cost will slightly differ from that of the base Statue plus cost of the upgrade.
