Helldivers 2 was initially reported to require 154GB of storage, aimed at accommodating older mechanical hard drives in PCs. However, analytics revealed that only 11% of players used HDDs, and the main cause of slowdowns was level generation rather than asset loading. In response, Arrowhead is testing a "slim" version of the game in public beta, which is 23GB, significantly reducing the storage requirement while maintaining gameplay integrity. This change allows players to install additional games, potentially fitting at least 13 indie city-builders in the space previously occupied by the original version.
