When Hell Let Loose first arrived, it set itself apart by refusing to chase spectacle. While many shooters focused on speed, killstreaks, and individual hero moments, it built its identity on communication, teamwork, and battlefield discipline. Success was rarely about one player carrying the match. It was about fifty people working together. Hell Let Loose: Vietnam appears ready to preserve that philosophy while moving the franchise into one of modern history’s most brutal and complex conflicts.
Leaving behind Europe and the Pacific theatres of World War II, Expression Games is transporting players into the dense jungles and river systems of Vietnam. The tone shifts immediately. Visibility shrinks. Terrain becomes unpredictable. Every tree line feels threatening. The battlefield itself becomes part of the conflict.
Gameplay
The biggest change comes through the game’s asymmetrical approach to warfare. United States forces rely heavily on superior technology and firepower. Helicopters introduce entirely new tactical possibilities, enabling aerial transport, supply runs, and support operations. River patrol boats extend combat onto waterways, while artillery and coordinated assaults remain central to battlefield control.
The North Vietnamese Army fights differently. Stealth becomes their greatest weapon. Dense foliage provides cover. Most importantly, the newly introduced tunnel network allows NVA players to build underground routes for repositioning and ambushes.
This mechanic alone could reshape how battles unfold. Instead of predictable front lines, objectives may suddenly come under attack from enemies emerging from beneath the jungle floor. It introduces uncertainty into every engagement and captures the asymmetric nature of the conflict remarkably well.
Movement systems have also expanded significantly. Swimming, climbing, fast crawling, and dragging wounded allies away from active firefights all add immersion. These features may sound small individually, but together they strengthen the slower, methodical pacing the series is known for.
Squad Roles & Teamwork
Large-scale warfare remains at the heart of the experience. Matches still support fifty players per side, but the role system has grown considerably. Nineteen specialised roles across infantry, recon, armour, helicopters, mortars, and command units provide impressive tactical flexibility. Helicopter squads stand out immediately. Pilots, crewmen, and gunners have distinct responsibilities that extend beyond combat. Logistics becomes as important as firepower.
Mortar teams introduce indirect support options, while recon units continue to provide battlefield intelligence. Importantly, the chain of command remains intact. This is still Hell Let Loose. Squad leaders coordinate movements. Commanders issue orders. Support players keep offensives alive. Lone-wolf tactics will likely remain ineffective. For returning players, that commitment to teamwork will be reassuring.
Maps & Atmosphere
Vietnam changes more than the setting. It changes how players think. The six launch maps draw inspiration from real-world locations and feature dynamic weather and lighting variations. Dense jungle paths, mountainous regions, rivers, valleys, and fortified locations appear throughout the preview footage.
The upcoming Thanh Hóa Bridge map, arriving during the open beta, looks especially promising because it showcases multiple gameplay systems simultaneously. River combat, patrol boats, jungle ambushes, and large-scale assaults intersect there.
Visually, Unreal Engine 5 already seems to be delivering the atmosphere Expression Games is aiming for. Sunlight filters through thick canopies. Fog settles across riverbanks. Vegetation obscures movement. The environment feels oppressive and unpredictable. The jungle is not simply scenery. It feels alive.
Technical Outlook
Despite the excitement, there is understandable caution about the project. Preview builds have generated positive impressions of the atmosphere and authenticity, but community discussions have also highlighted areas still needing refinement. Spatial audio positioning and vehicle handling appear to be the most common concerns.
Expression Games has already acknowledged these issues, and recent updates suggest both systems remain active development priorities. The upcoming PC open beta, running from May 29 to June 1, will likely be the first major test of whether those improvements are landing successfully. Given the game’s scale and ambition, these tests feel essential.
Final Thoughts
Hell Let Loose: Vietnam looks far more ambitious than a simple setting change. Helicopters, tunnel warfare, river combat, asymmetrical factions, expanded movement systems, and large-scale environmental design all suggest Expression Games wants to evolve the series rather than repeat it.
That ambition carries risk. Every one of these systems needs to work together smoothly in battles with hundreds of players. Still, the early signs are promising. The oppressive atmosphere feels right. The tactical depth remains intact. The move towards asymmetrical warfare could introduce entirely new layers of strategy. Most importantly, the game still seems committed to what made Hell Let Loose special in the first place. Teamwork. Communication. Survival. If Expression Games can bring everything together, Hell Let Loose: Vietnam could become one of 2026’s standout tactical shooters.
