Helldivers 2 Storage Crisis Solved

#gamedev #news #derex #derexxd

Announced in Arrowhead Studio’s “Tech Blog 2”, the PC version of the videogame Helldivers 2 has undergone a significant transformation in how it handles storage. What began as a technically driven approach to support older hard drives eventually resulted in a much larger installation footprint than most players expected. As the community dug into the game’s file structure and shared their findings, Arrowhead evaluated the situation and began reworking the underlying system, resulting in early public betas being released, successfully cutting down the game install size by over 100 GB.

Here’s a timeline detailing the issue, and how the developers listened to the community and implemented a standard of optimization we can only hope for more AAA studios to adopt.

Background

When Helldivers 2 launched on PC in 2024, its install size was large but not unusual for a modern game. With how much fun it was during those first months in Spring of 2024, it was easy to overlook the weight of the game’s installation files. Over the following updates, however, the game grew steadily, eventually surpassing 150 GB, far larger than the console versions even though maps, features, and gameplay remained the same. Players began to wonder why the game needed so much space, especially compared with other titles of similar size and scope.
Community members who looked into the game’s files found that a significant portion of the data consisted of duplicated assets, originally designed to help players using older mechanical hard drives (HDDs) by placing frequently used files in multiple locations, reducing load times on slower drives. By late 2025, what had started as a technical optimization for legacy hardware had become a widely noticed storage issue, especially for players with limited SSD space.

Date / Period	Event / Discovery / Action
Launch 2024	Helldivers 2 releases on PC. The base install size is already sizable, with some users citing over 100 GB for early builds according to player discussions.
2024 to Early 2025	Gradual growth with each content update or patch, the installed size increases. Players begin to notice that updates feel large and the install footprint keeps growing even when content additions seem modest according to community posts.
June 2025	On community forums and Reddit, several players report that after a recent update the game’s file size jumped to approximately 120 GB. Some express concern that repeated patches are compounding storage demands. Users draw comparisons with the smaller installation size on consoles, which used Sony’s Kraken compression according to forum discussions.
Mid / Late 2025 pre-October	Through player-driven file audits and aggregated reports, the community begins to understand the root cause as massive asset duplication within the PC build. Some reports claim that while total install size exceeds 130–150 GB, the unique content is much smaller meaning the rest is duplicated data according to community research and statements on data duplication.
Early October 2025	Official acknowledgement: Arrowhead Game Studios published a “Tech Blog #1 – Install Size” explaining that the PC version’s 150 GB+ install size is largely due to duplicated data originally intended to optimize HDD loading. They note that this makes the PC install around three times larger than the console version. Arrowhead begins exploring long-term solutions such as removing HDD-specific duplication, optimizing data architecture, and preparing a revised build aimed at reducing storage demands according to reporting on developer plans.
December 2, 2025	Major update, “slim version” beta released on PC. With the help of porting-specialist Nixxes Software, Arrowhead optimizes a vast portion of the game’s data. The official PC Installation Size entry for the patch notes reports a reduction from approximately 154 GB down to 23 GB saving roughly 131 GB or 85 percent. They note this is more optimistic than previously anticipated, with much less negative impact on HDD users according to Steam patch notes.
December 2–3, 2025	Community reaction: many players test the slim build and report success. On Reddit and other forums, players express surprise and relief at how much space is freed. Some note they can reinstall Helldivers 2 without sacrificing other large games according to player testimonials on the beta release.
Post-beta / December 2025 onward	The developers confirm there are no content or gameplay changes. The slim build retains full parity with the legacy version including the same maps, progression, and multiplayer compatibility. They plan to roll out the slim version as the default for all PC users once testing completes according to developer statements and media coverage.

Conclusion

The release of the slim build for Helldivers 2 is proof of how much modern games can be optimized. That the PC version is now roughly the same size as Portal 2, a game released over a decade ago, highlights just how much unnecessary data had accumulated and suggests that many other large titles could benefit from similar efficiency improvements. While this is still a beta, the fact that Arrowhead has delivered a tangible result after months of smaller updates is encouraging. It shows a commitment to performance and player experience, particularly for those who had been advocating for a focus on optimization over constant content releases.

I think it’s funny how people are drawing comparisons to notoriously large titles like Call of Duty, which shows just how significant these optimizations are in today’s gaming landscape and how big studios probably have the capacity to do so.
