Scrap

Scrap is the main resource Aquinas uses to development new technology.

After destroying enemies, Aquinas can run over the corpses to collect scrap. He can also let his robot companion Theo recolect scrap autonomously.

To increase your scrap gains use Aquinas' Greedpunk suit.

To use your Scrap, after every run go to Aquinas'lab and click the action button on the Tech Tree.
