Upgrades

UPGRADES are a feature that allow you to spend cash to increase income.

Trivia
220I is the last upgrade for players who have transcended. I do not know what the cost of the last upgrade is if you don't transcend.

How to get them
You need to have at least as much cash as required for the upgrade to buy it. The Buy ALL button allows you to buy all affordable upgrades at a rate of 100 upgrades/sec. Your lifetime earnings must be higher than 1AA to unlock this feature.
