Helldivers 2 Trims PC Install Size by 85%

03 Dec 2025

Helldivers 2, developed by Arrowhead Game Studios, has significantly decreased its PC install size from 154 GB to 23 GB. This reduction was made possible by using deduplication techniques with assistance from Nixxes Software.

Install Size Optimization

The original hefty install size was caused by duplicated assets designed to enhance loading times on mechanical hard drives. A new analysis revealed that only 11% of players rely on HDDs, with mission loading times seeing minimal impact.

  • The original install size was approximately 154 GB.
  • New size after optimization: 23 GB.
  • Deduplication efforts were supported by Nixxes Software.
  • Only 11% of users play on mechanical hard drives.
  • Loading speed minimally affected, increased by a few seconds.

Beta Version Offering

Arrowhead has launched a 'slim' version of Helldivers 2 via Steam beta. This version maintains full game functionality, preserving player progression, war contributions, and in-game purchases. Players have the option to exit the beta whenever they choose.

By reducing the unnecessary data load, Helldivers 2 makes better use of modern PC storage environments, focusing on efficiency and user choice.
