Hell Let Loose: Vietnam Patch 1.2 Adds 500+ Fixes and a Roadmap to 2026

Hell Let Loose: Vietnam is getting a serious round of upkeep with the arrival of Patch 1.2, and the changes don’t stop at bug fixes. The multiplayer Vietnam-set shooter from Expression Games has received more than 500 improvements across all platforms, with the studio also publishing a development roadmap that reaches well into 2026.

Patch 1.2 rolls out with 500+ fixes

Patch 1.2 brings adjustments to every map in the game, including visual improvements tied to water, fixes for collision detection issues, and changes to overall detail levels. Audio has also been targeted: helicopter sound effects were updated because they were previously too quiet when players were nearby, and gunshot audio for the .50 cal HMG and the light machine gun was tuned so those sounds are easier to distinguish during firefights.

Vehicle gameplay has been adjusted as well. Truck speed has been increased, and tank commanders no longer have to worry about the smoke cover limit in the way they used to. Using smoke now only impacts a two-minute cooldown timer, rather than imposing the prior restriction. On the interface side, the tactical map received improvements, and the UI now warns players when they try to duplicate key bindings.

Expression Games says a full changelog is included in its official patch notes, but the headline is clear: Patch 1.2 is a broad pass over presentation, audio clarity, controls, and vehicle/QoL behavior—delivered in a single update.

Roadmap points to new weapons, maps, and factions in 2026

Alongside the update, the studio shared what’s next for Hell Let Loose: Vietnam. Patch 1.3 is planned for the coming week, focusing on server-related issues such as resetting settings after a server crash or restart, plus fixes for a problem where the scoreboard could not be opened from the screen shown after a character dies.

Looking further ahead, the roadmap lays out multiple content drops for 2026. Update 1.5 is scheduled to introduce the M14 and the SKS Type 56, and it will also add the Huey—an officially licensed recreation of the Bell UH-1 Iroquois helicopter. Passengers will be able to start and play onboard radio, with music tied to Vietnam-era sound, and nearby soldiers will hear it as well. The studio also notes that the effect will become stronger when multiple synchronized vehicles are running.

Update 1.5 is expected to arrive in September. After that, Update 2.0 will expand the U.S. forces with Australian and New Zealand allies under the ANZAC banner. That update will add three new weapons—L1A1 SLR, F1 SMG, and L16A1—plus a new map called Khe Sanh. The roadmap then culminates with Update 3.0, which will introduce armored vehicles for both sides.

Update 3.0 also brings additional units and gear: Green Berets and Navy SEALs are planned, along with four weapons including the MAT-49 SMG, SVD Dragunov, Stoner 63, and an M14 equipped with a scope. A new map named Rung Sat is also on the way, set in swamp and jungle terrain. The studio states that both Update 2.0 and Update 3.0 are expected to debut later this year.

The final item on the roadmap is “Battalions,” described as a system designed around player communities. The goal is to support group creation, identification, and tracking member statistics, including easier ways to join servers together. The first version will provide the foundational elements of the feature.

Hell Let Loose: Vietnam launched on August 13 on PC and on PlayStation 5 and Xbox Series X/S.
