The Plutonium Upgrade Dropdown

The plutonium upgrade dropdown contains permanent upgrades you can purchase with plutonium. Plutonium can be obtained in a variety of ways.

  • Achievements

  • Each earned prestige point awards some plutonium.

  • You can spend prestige points on plutonium as well.

  • You can also earn plutonium by watching ads

    • The amount earned can be increased with energy upgrades

  • You can also purchase plutonium in the shop. This is optional, as it's possible to earn plenty of plutonium with the methods above, given enough time.


If your just starting, it's recommended to buy mostly level one upgrades first, but use your best judgement based on pricing. Also note, there is an energy upgrade autobuyer in the level 4 upgrades.

More options will be added in the future.
