Following the successful Helldivers 2 collaboration with the Killzone franchise, speculation is mounting regarding a potential crossover with another popular franchise: Warhammer 40,000. While some doubted Games Workshop's willingness to participate, Arrowhead Studios head Shams Jorjani stated: "I can say that GW would love a crossover, we're big fans of [Warhammer] 40k ourselves." This statement fueled fan hopes for a future collaboration.
Helldivers 2's premium content now focuses on carefully selected thematic partnerships, exemplified by the Killzone 2 collaboration. The developers have confirmed that such crossovers will remain infrequent, only occurring when they organically enhance the game's established universe.
The current Killzone-themed partnership includes a community challenge tied to Galactic War, offering players the chance to earn additional Killzone-themed rewards based on overall community performance.
