The game has two main currencies—Gold coins and Cash. Cash is the type of currency that is easier to collect as players are rewarded with Cash after every mission. Cash is also used to upgrade weapons and other equipment in the game.
Meanwhile, Gold is the premium currency as it is hard to collect and it is used to purchase the more special boosters, gadgets, and even weapons. Using Gold can also be used to upgrade weapons.
