What are codes in MM2 used for?
In the past, codes in the game offer in-game rewards like free gold, new knives, and pets. With gold, you can purchase awesome weapons, effects, powers, emotes, radios, and pets at the shop. Among these, the powers are quite useful as they give you certain skills and attributes.
