Helldivers 2 has a storage requirement of 150GB on PC, which is about three times larger than on Xbox Series X|S and PlayStation 5. The large install size is designed to accommodate PC users with mechanical hard disk drives (HDDs) by duplicating data to improve loading times, although this is unnecessary for users with solid state drives (SSDs). Current estimates suggest that around 12% of PC gamers still use HDDs, but reliable data on this is lacking. Arrowhead Game Studio plans to reduce the game's file size in an upcoming update and bundle common assets to minimize duplication, though this may slightly increase load times for HDD users. The studio aims to keep load times under 30 seconds and is also working on improving its engine and compression techniques. Additionally, Arrowhead's CEO expressed a commitment to the game's longevity rather than developing a sequel, and the studio is addressing various technical issues with planned updates.
