In a post-apocalyptic sci-fi world, every resource is precious as you battle against machines corrupted by the "Punishing" virus. Punishing: Gray Raven (PGR) is an ARPG renowned for its fast-paced combat and deep storyline. The most strategic and premium currency in this universe is the Rainbow Cards unit.

   

What Are Rainbow Cards (RC) and What Are They Used For?

Rainbow Cards are the most valuable currency in the game and can only be obtained with real money. To upgrade your Constructs and complete your collection, you can use them in the following ways:

• Black Card Exchange: The most common use is to exchange Rainbow Cards for Black Cards (BC), the main gacha currency. The standard exchange rate is 1 RC = 10 BC.

• Monthly Passes: You can purchase monthly packs with the best value for money directly with RC. These packs provide you with a daily supply of Black Cards and Serum (Energy).

• Exclusive Skins and Outfits: The coolest and rarest cosmetic skins designed for your characters are usually only available with Rainbow Cards.

• Limited-Time Bundles: Access special bundles released with each new update, including character upgrade materials and R&D tickets.
