Following the successful Helldivers 2 crossover with the Killzone franchise, speculation is mounting regarding a potential collaboration with another popular franchise: Warhammer 40,000. While some doubt 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 has fueled fan hopes for a future Warhammer 40,000 themed expansion.
Helldivers 2's premium content now focuses on carefully selected collaborations, exemplified by the Killzone partnership. The developers have confirmed that such crossovers will remain infrequent, only occurring when they seamlessly integrate with the game's established lore.
The current Killzone-themed Galactic War community challenge offers players the chance to earn additional rewards based on overall team performance.
