To retire your common heroes in exchange for resources you have two options.

• The first option is to go hero by hero, entering the hero screen and tapping on the “retire” button.
• The second option is to allow the game to perform this process automatically. You can activate this option through a toggle button you can find in the heroes shop, the collection screen or the new heroes screen. (This option will only retire the new common heroes you obtain, not the ones you already own).

Retiring your common heroes will grant you a variety of regular resources plus an amount of a special resource called DNA Sequencer Currency.
