Survivor:Credits

Credits are used to purchase permanent Upgrades from the main menu.

All resources collected during a dive award Credits at the end, including Gold, Nitra, and Upgrade Resources. Credit payments are based on what is picked up, not the remaining amount of resources at the end of the dive, so Gold and Nitra can be freely spent on upgrades.

Morkite also earns Credits, even after completing the objective to gather it, but Boloo Caps and Apoca Blooms do not. According to a developer, this is an oversight as of version 0.2.146d.

In addition to collecting resources, Credits are awarded for every bug killed. All enemy types pay the same amount.

Every character level reached during a dive awards Credits.

Higher hazard levels pay more Credits, and progressing further in a dive awards more Credits, including a bonus for successfully completing it.
