Following the successful Helldivers 2 crossover with the Killzone franchise, speculation is mounting regarding a potential collaboration with another iconic universe: Warhammer 40,000. While some doubt Games Workshop's willingness to participate, Arrowhead Studios head Shams Jorjani has 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 Warhammer 40,000 collaboration.
Helldivers 2's premium content now focuses on carefully selected thematic partnerships, exemplified by the Killzone 2 collaboration. The developers have emphasized that such crossovers will be infrequent, occurring only when they organically enhance the game's existing world.
The Killzone partnership also includes a community challenge tied to Galactic War, offering players the chance to earn additional Killzone-themed rewards based on overall community performance.
