Credits

Credits are the currency of the game, and usually the primary deciding factor of what you can't or can't do.
You can get credits by either winning cold war's/apocalypse gamemodes, capturing fountains, or selling materials and items. If you gain above 99999 credits the produce menu display will not show your current number of credits.
