CD Projekt and Blizzard revealed a Geralt-themed Barbarian skin for Diablo 4, available only to players who preorder The Witcher 3 expansion Songs of the Past on Battle.net, excluding Steam players and causing backlash from fans who already own The Witcher 3 on other platforms. The collaboration marks the first of multiple planned Witcher-inspired content pieces coming to Diablo 4 in 2027.
