As you continue on your journey, you will be joined by Heroes lost in time!

Heroes will lend you their wisdom and power to automate resources and give unique boosts. You can sort your Heroes by tapping the "Sort" button in the top right of your screen. You can sort your Heroes by Rarity, Age, or Level Up!

As you discover more of each Hero you find, you will be able to increase their abilities with XP! A small number next to each Hero card will show you how many of that Hero you have found.

When you've gathered enough XP and collected enough of a particular Hero , you will see a green arrow next to their card. This indicates that they are ready for a promotion!

Remember, Agent: the more promotions a Hero has had, the more XP you'll need to level them up further.
