Arrowhead Game Studios has released a slim version of Helldivers 2 for PC, slashing the install size from 154GB to 23GB. This 85 percent reduction removes duplicated assets while minimally impacting load times. Players can opt into the beta version on Steam to access the update immediately.
Update Overview
On December 2, 2025, Arrowhead Game Studios announced a major optimization for the PC version of Helldivers 2, their 2024 co-op shooter. The update, developed with assistance from Nixxes Software, reduces the game's install size by approximately 131GB, bringing it down to 23GB from the previous 154GB. This addresses long-standing complaints from PC players about the bloated file size, which was significantly larger than the console versions at around 22GB.
Reasons for the Large Size
The original PC build included redundant duplicated assets to optimize loading times for users with mechanical hard disk drives (HDDs), a technique reminiscent of older disc-based games. Console versions, running on solid-state drives (SSDs), did not require this. Arrowhead's blog post explains that testing revealed the majority of load times stem from level generation, not asset loading, allowing safe removal of duplicates without major performance hits.
Performance Impact
For HDD users, load times may increase by only a few seconds, far less than the studio's initial projections of up to 10 times slower. Arrowhead stated, 'We now know that, contrary to most games, the majority of the loading time in Helldivers 2 is due to level-generation rather than asset loading.' This parallel process ensures the change is a 'worthy tradeoff' for the space savings.
How to Access the Slim Version
The reduced size is available as an opt-in beta on Steam:
- Right-click Helldivers 2 in your library and select Properties.
- Go to the Betas tab.
- Choose 'prod_slim' from the dropdown.
- The game will update automatically.
Players can opt out if issues arise. Once testing confirms stability, the slim version will become default, with the legacy version discontinued next year to avoid development burdens. Arrowhead emphasized the 'very minor differences in loading times' between versions.
This update coincides with the launch of the delayed Python Commando Warbond, which adds new weapons like a flame-spewing drone and minigun, following bug fixes prioritized by the team.
