QUICK ANSWER

The official 2026 roadmap still centres on Updates 1.5, 2.0 and 3.0, but Community Update #2 adds two important confirmations. Night-time experiences and weather are both part of the wider plan. One is further along than the other, but the developers did not identify which one or attach either feature to an update or date. Update 1.5 remains the only major roadmap update with a stated month: September 2026. Updates 2.0 and 3.0 have named content but no exact dates.

Night maps and weather are confirmed—but undated

Community Update #2 changes the status of two frequently requested features. The developers say that both night-time experiences and weather are part of the wider plans for Hell Let Loose: Vietnam. They also say one is further along than the other, without identifying which.

That confirmation does not establish a release window. The update does not name a map, weather type, game mode or technical format, and it does not say whether conditions will be fixed, dynamic or optional. It is therefore not accurate to place night maps or weather in Update 1.5, 2.0 or 3.0 until an official schedule does so.

Update 1.5: September weapons and the licensed Huey

Update 1.5 is the only major roadmap update given a clear month in the official article: September 2026. It is described as the first update to introduce new content after launch.

Important wording: the M14, SKS and licensed Huey are presented as Update 1.5 content. The radio section says the team is “looking to bring” the feature, so treat its detailed implementation as planned rather than an unconditional final specification.

Update 2.0: Khe Sanh and the ANZAC expansion

Update 2.0 introduces the first post-launch battlefield, Khe Sanh. The official description promises a different visual and tactical character from the six launch maps but does not yet publish layout, game-mode support or an exact release date.

The US faction will expand into US & Allies when Australian and New Zealand Army Corps representation arrives. US and ANZAC weapons and personalisation will share the same Barracks, with restrictions on which equipment can be combined.

Update 3.0: Rung Sat, APCs and six named additions

The second post-launch map is Rung Sat, built around swamps and jungles. Update 3.0 also introduces Armoured Personnel Carriers for both sides. Their exact models, crew rules and battlefield role will be explained closer to release.

US & AlliesStoner 63, a scoped M14 variant, Navy SEALs and Green Berets

Battalions V1: the planned clan system

Battalions is a separate, undated roadmap feature for clans and organised communities. The first version is intended to let players:

The developers describe this as a foundation that will evolve with community feedback. Community Update #2 also confirms that Commendations and more detailed player statistics are planned for the future, alongside further Battalions improvements. It does not attach those additions to a date or publish their unlock and progression rules.

Quick Play and traps have different official statuses

The developers are assessing the community request for Quick Play. They describe it as difficult to implement but say they are open to exploring it. That is an investigation, not a roadmap commitment.

Traps are not currently planned. The team says it will keep working on faction asymmetry, but that broader direction should not be rewritten as a promise to add placeable traps.

What remains undated or unconfirmed

Optimisation continues alongside new content

Team17 says fixes, polish, optimisation and quality-of-life improvements remain a priority across PC, PlayStation 5 and Xbox Series X|S. Patch 1.3 is now live, and further repairs will continue through major updates, regular patches and necessary hotfixes. Content and repair work therefore remain parallel tracks.

Bottom line

The roadmap now answers the biggest content questions with named maps, weapons, groups and vehicles. September's Update 1.5 is the most concrete milestone. Night experiences and weather have moved from ideas to confirmed wider plans, but not to a dated update. The safest reading is to separate confirmation from scheduling: Khe Sanh, Rung Sat, ANZAC, APCs, night and weather are planned, while their later dates and final mechanics still need follow-up announcements.
