Steam Hell Let Loose: Vietnam Officially Launches

Official Launch and SteamOS Support

Hell Let Loose: Vietnam is a tactical online shooter from Expression Games / Team17, and it has now officially launched, meaning the game has moved out of its testing phases and into full release.

The official launch announcement also confirms that the game works on SteamOS / Linux, which is a notable point for players who use Linux-based systems or SteamOS.

Since the title is available through Steam, the SteamOS/Linux compatibility means users on those platforms are not left out of the launch and can play the shooter on their systems.

The launch thus positions the tactical shooter as a Steam release that also accommodates Linux-based setups, giving SteamOS/Linux users a confirmed option from the official launch.

Crossplay Playtest and Community Response

Before the official launch, the development team held a Crossplay Playtest that was described as part of the road to launch.

The team thanked the hundreds of thousands of players who participated in the playtest over the course of the previous weekend, a strong sign of community interest.

During the playtest, players on Steam, PlayStation, and Xbox took to the battlefield together, showing the game’s cross-platform reach.

The playtest period also produced clips, screenshots, and feedback, all of which were highlighted by the team as incredible community contributions.

Open Beta Details

An Open Beta for Hell Let Loose: Vietnam was made available on PC Steam, giving players on the platform a specific window to try the game.

The Open Beta announcement confirmed the beta was live at the time of the announcement, although it noted a small delay to the planned start.

The beta’s end time was set for Monday, 1 June 2026 at 09:00 PDT, which corresponds to 14:00 BST.

Another announcement added that the Open Beta would go live on Steam on 29 May and continue through the weekend until 1 June, giving players several days to participate.

Thanh Hóa Bridge and Game Modes

The map used for the Open Beta was Thanh Hóa Bridge, which served as the setting for the weekend’s combat.

Players could take part in Warfare and Offensive, the two game modes associated with the Open Beta.

The team specifically looked forward to seeing players jump into the fight on Thanh Hóa Bridge across both Warfare and Offensive game modes throughout the Open Beta weekend.

War Correspondents Showcase

A War Correspondents Showcase for Hell Let Loose: Vietnam was made available to players.

The showcase focused on the gameplay roles that are part of the game.

It appeared alongside the Open Beta announcement, giving players more context about what to expect in the battlefield.

Building Toward Launch

The post-playtest message framed the Crossplay Playtest as part of the road to launch.

Both the playtest and the Open Beta gave players on different platforms opportunities to engage with Hell Let Loose: Vietnam before the full release.

Now that the game is officially launched and works on SteamOS/Linux, the public testing phase has given way to full availability.
