5 Major Helldivers 2 Crossover Events And Rumors: ODST, Killzone's Return, And The Next Confirmed Collaboration

The Helldivers 2 universe, a brutal and hilarious satire of military sci-fi, is constantly expanding, not just through the relentless Galactic War against the Terminids and Automatons, but also through massive in-game events and, crucially, high-profile crossovers. As of today, December 16, 2025, the community is buzzing with officially confirmed content returning this week, a major collaboration tied to a new platform launch, and the exciting confirmation of a brand-new, top-secret event already in the works by Arrowhead Game Studios.

The developers have successfully established Helldivers 2 as a premier live-service game, making it a prime candidate for collaborations that deepen its topical authority. The focus for 2025 is clearly on bringing highly-anticipated content to the masses while simultaneously laying the groundwork for future, unexpected partnerships.

The Confirmed Crossovers and Returning Content for Late 2025

While the Helldivers are busy spreading Managed Democracy across the galaxy, the game masters at Arrowhead are preparing two major content drops that involve collaborative gear, one of which is an immediate return and the other a blockbuster event tied to a major platform expansion.

1. The Killzone Legendary Warbond Returns (December 18, 2025)

For players who missed out on the initial drop, or for those new to the fight, the popular Killzone crossover content is making a permanent return to the game in the form of a Legendary Warbond. This is an immediate and fresh update, scheduled to go live on December 18, 2025.

• Content: The Warbond brings back the Killzone-inspired gear, which was previously available but caused some controversy over its initial pricing structure.
• Cost: The Legendary Warbond will cost 1,500 Super Credits, which can be purchased or earned through gameplay.
• Significance: This move by Arrowhead Game Studios demonstrates their commitment to player feedback, ensuring that highly-demanded cosmetic items from previous collaborations are accessible to the entire player base without the pressure of a limited-time event.

2. The Highly Anticipated Halo 3: ODST Crossover (August 2025)

Perhaps the biggest and most exciting news is the widely reported and essentially confirmed collaboration with Microsoft’s iconic Halo franchise, specifically featuring gear inspired by the Orbital Drop Shock Troopers (ODST).

This massive crossover is strongly linked to the rumored launch of Helldivers 2 on Xbox consoles, a significant moment as it would be the first PlayStation-published game to appear on Microsoft’s platform.

• The Event: The ODST crossover is rumored to arrive around August 26, 2025, coinciding with the potential Xbox launch.
• The Gear: Expect a new Warbond featuring the sleek, recognizable ODST-style armor and perhaps new weapons that align with the human-focused weaponry of the Halo universe. The armor is expected to feature durability-focused passives, fitting the lore of the heavily armored troopers.
• Community Buzz: The collaboration is considered a perfect thematic fit, as both the Helldivers and the ODSTs are elite, drop-in shock troops fighting overwhelming alien forces. The presence of a musical sting resembling the Halo theme in a previous trailer only fueled the speculation before the official reveals.

The Future of Collaboration: What’s Next for Super Earth?

Beyond the confirmed and highly-credible leaks, Arrowhead Game Studios has already confirmed they are working on a completely new, unannounced collaboration event. This indicates that the current crossovers are just the beginning of a long-term strategy to keep the Galactic War fresh and engaging for the Helldivers community.

3. Arrowhead’s New, Early-Stage Collaboration (TBA)

Arrowhead Game Studios has officially stated that a new collaboration event is currently in the "very early stages" of development. While no specific details were provided, this confirmation is a signal that the studio is actively pursuing external partnerships to bring new content, weapons, and cosmetics into the game.

This new event will be distinct from the returning Killzone gear and the upcoming ODST content, suggesting a third major collaboration is on the horizon. The nature of this event—whether it's another video game, a movie, or an entirely different IP—remains a mystery, fueling intense community speculation.

4. The Warhammer 40,000 Tease and Leaks

The dark, satirical tone of Helldivers 2 and its constant war against alien hordes makes it a spiritual successor to the grim universe of Warhammer 40k. The community has long clamored for this crossover, and there have been strong indications that it may be a reality.

• Thematic Fit: The Helldivers’ motto, "For Super Earth!" and their over-the-top patriotism perfectly mirror the "For the Emperor!" battle cries of the Space Marines and the Imperial Guard.
• Teased Content: Leaks have pointed toward a potential collaboration that could coincide with the launch of Warhammer 40k: Space Marine 2. Imagine Stratagems that call in a small-scale Orbital Bombardment or armor styled after the iconic Astartes power armor—a dream for many players.

5. Community Wishlist and High-Demand Crossover Entities

The Helldivers community is never short of ideas for which franchises should join the fight for Democracy. These potential crossovers are frequently discussed on forums and Reddit, representing the strongest LSI keywords for future content:

• Starship Troopers: This is arguably the most requested crossover, as Helldivers 2 is heavily inspired by the 1997 film. A collaboration could bring iconic gear, weapons, or even new enemy variants that closely resemble the Arachnids from the film.
• Deep Rock Galactic: The co-op PVE nature of Deep Rock Galactic, combined with its distinct sci-fi aesthetic, makes it a popular choice. Players imagine dwarf-inspired armor sets or a new Stratagem that calls in a supply pod from the DRG universe.
• Alien/Predator (The AVP Universe): Given the game's focus on fighting bug-like aliens (Terminids) and advanced robots (Automatons), a crossover with the Alien franchise would be a terrifyingly good fit. New missions could involve fighting a new, Xenomorph-like enemy type or unlocking Weyland-Yutani-inspired gear.
• Sabaton: An unusual but frequently requested collaboration involves the Swedish power metal band Sabaton, known for their war-themed songs. This would likely manifest as a new in-game Warbond featuring unique armor, cape cosmetics, and perhaps a new musical track for the Super Destroyer.

The future of Helldivers 2 is bright, with the game's developer, Arrowhead, clearly embracing the crossover potential. The immediate return of the Killzone Warbond and the highly-credible ODST/Halo event set a high bar for the quality and scale of future collaborations. The confirmation of a new, early-stage collaboration means that the Super Earth government will continue to bring in new allies and gear to fight the good fight for Democracy well into 2026 and beyond.
