Hell Let Loose: Vietnam Devs Detail Post-Beta Optimisations

Expression Games and Team17 have released the second episode of their Command Post developer blog series. This latest update focuses on the technical side of development, highlighting performance optimization following the game’s recent public playtest.

Analysing Open Beta Data for Launch Optimisation

Game Director Paul “Rushy” Rustchynsky and Studio Technical Director Kieran D’Archambaud shared how the team is utilizing metrics gathered during the recent Open Beta. The playtest exposed the game to a massive range of PC configurations, revealing performance bottlenecks that did not show up during internal tests.

According to the developers, these real-world data points are guiding current optimization passes. The team is addressing frame rate drops and stuttering across various CPU and GPU setups to ensure smoother gameplay when the 50v50 tactical shooter launches. These adjustments are expected to refine the final system requirements and improve performance on lower-spec machines.

Preparing for the Crossplay Playtest

A key highlight of Command Post #2 is the preparation of a new build designed for an upcoming crossplay playtest. While the studio has not yet confirmed the exact scope of crossplay support, the developers are focusing on stabilizing network performance and client-side frame rates before this test phase begins.

In the original tactical shooter, crossplay was limited to consoles, keeping PC lobbies separate. Whether Expression Games will maintain this separation or implement console-only cross-platform matchmaking for the Vietnam spin-off remains a point of community speculation.

What Lies Ahead for Hell Let Loose: Vietnam

With the launch set for August 2026, these technical updates are crucial for ensuring the game can handle the demands of its dense jungle environments and new mechanics. The addition of complex systems like pilotable helicopters and underground tunnel networks adds significant CPU overhead.
