Hell Let Loose – Dev Brief #219 | First U21 Experimental Branch Test | Weapon & Armor Changes

Summary

### What’s in the First Update 21 Experimental Branch Playtest?

Hello everyone,

Welcome to our first playtest for Update 21 coming later this year. Update 21 introduces a number of new additions, alongside significant changes to several core gameplay systems that we're excited for you to get hands-on with.

The Experimental Branch playtest will kick off Friday 7 August, at 6am PDT | 9am EDT | 2pm BST | 3pm CEST.

Conquest Mode

Many of you may have already had the opportunity to test Conquest in our v1 and v2 tests earlier in 2026. We are now excited to reveal that Conquest will officially be joining Hell Let Loose as part of Update 21 (as well as being one of the four game modes that will be in Hell Let Loose: Vietnam).

Conquest has gone through a lot of changes and iterations throughout its development and has been guided by much of the feedback we received after the previous two playtests.

If you're interested in learning more about how the new mode works, be sure to head over to watch the Dev Diary we released in conjunction with the first test where Matt and Xander break down the fundamentals of the mode.

1. Juno Beach - Day
2. Carentan - Day

We can’t wait for you all to share your thoughts as this game mode will continue to be developed and updated based on community feedback.
