Team17 and Expression Games released Hell Let Loose: Vietnam on 13 August 2026 for PC, PlayStation 5, and Xbox Series X|S. Shifting the series' focus from World War II to the Vietnam War, the title utilizes Unreal Engine 5 to render dense jungle environments and realistic lighting. The game launched as version 1.0 following an open beta with 352,000 players and a delay from its original June window to allow for technical polishing. While the title achieved a record-breaking Steam launch with 30,614 concurrent players—a 43.2 percent increase over the previous title’s peak—it has faced a difficult reception. The game holds a 57 percent positive rating on Steam, with approximately 41 percent of users providing negative reviews citing optimization issues and performance instability.
