Kingside Break cosmetic DLC is licensed for use only inside Kingside Break. It may not be exported,
transferred, sublicensed, traded, resold, tokenized, or used as an NFT. Distributed DLC contains
only the compiled content and runtime dependencies required by the game; it does not grant reusable
source art, editor scenes, creator tools, or an export right.
Cosmetic DLC does not change chess rules, AI strength, campaign access, rewards, or player power.
Purchases and platform services are also subject to the applicable Steam Subscriber Agreement and
Valve policies. Steam processes payments, refunds, account access, licenses, and downloads.
