Carp is one of the three skins released under the Chinese New Year offer. It could be purchased individually using game coins in January 2017.
Carp could be purchased in the Skins Shop under the ‘Chinese NY’ tab for 690 coins. However, this skin may not be available for purchase in the future.
Note: Carp was released again at the same price with the Chinese New Year offer in late February 2018.
Details of this offer can vary depending on location, platform or time.
