During the Opening Night Live event at Gamescom 2026, CD Projekt RED announced a major collaboration with Blizzard Entertainment. The Witcher series will make its debut on the Battle.net platform, accompanied by exclusive crossover content with Diablo IV.
It is reported that The Witcher 3: Wild Hunt - Complete Edition will launch on the Battle.net platform on September 29, 2026. The story expansion "Old Tunes" will be released simultaneously on this and other platforms in 2027. All users who pre-order or purchase the "Song of the Past" expansion via Battle.net will receive an exclusive Geralt-themed cosmetic skin for Diablo IV.
Meanwhile, CD Projekt RED developers have confirmed their attendance at BlizzCon 2026 this September, where they will fully showcase the cosmetic item and announce other collaborative surprises. The company emphasized the historical significance of this partnership: in 1998, CD Projekt began by distributing Blizzard games in Poland, and nearly 30 years later, they are bringing their most important RPG title into the ecosystem of this American publisher.
