TL;DR
- Vietnam is a standalone game, not a DLC or expansion. You do not need to own the original to play it.
- The core loop is the same — 50v50, squads, chain of command, sector capture. The battlefield around it is very different.
- Vietnam adds helicopters (US only), NVA tunnels, patrol boats, and river combat — none of which exist in the original.
- Both teams now play completely differently from each other. The original game’s factions were more mirrored.
- Vietnam runs on Unreal Engine 5. The original runs on Unreal Engine 4.
- Vietnam adds two new game modes — Conquest and Domination — alongside the returning Warfare and Offensive.
- Full crossplay between PC, PS5, and Xbox Series X|S launches with Vietnam. The original never had this.
- Vietnam adds swimming, climbing, fast crawling, and the ability to drag wounded teammates.
- Both games continue independently. The original is not going away.
Hell Let Loose Vietnam vs original Hell Let Loose is a question a lot of players are asking right now, and it is a fair one. The game came out August 13, 2026, and if you put time into the original, you want to know whether this is worth treating as a fresh start or a minor upgrade. The short answer is that it is genuinely different. Not so different that veterans will feel lost, but different enough that some assumptions from the original will get you killed. This guide breaks down what actually changed and what stayed the same.
Is Hell Let Loose Vietnam a Sequel or a DLC?
Vietnam is a standalone game. You buy it separately, it has its own player base, its own Steam app ID, and it does not require you to own the original Hell Let Loose. It is not an expansion or a paid update.
The original game is also not being shut down. Expression Games and Team17 have kept both running with separate development teams. Veterans of the WWII game do not have to give anything up — Vietnam is an addition to the series, not a replacement for it.
What Stayed the Same
Before getting into the differences, it is worth being clear about what has not changed — because the foundation of the game is largely intact.
Both games are 50-versus-50 multiplayer tactical shooters. Both use the same squad structure: a Commander at the top, Squad Leaders reporting to them, and infantry filling the six-person squads below. Both games still run on sector capture as the primary objective. Garrisons, outposts, supply nodes, and chain-of-command communication are all still core to how the game works. Neither game is a run-and-gun shooter. Positioning, communication, and coordination still beat individual skill every time.
If you learned how to play the original well — how to build spawn points, how to read a frontline, how to listen to your Squad Leader and use voice channels — that knowledge moves straight into Vietnam. The language is the same. The battlefield it is spoken in is not.
The Biggest Single Difference: Asymmetric Factions
In the original Hell Let Loose, the two sides — Allied and Axis — had different weapons and uniform aesthetics, but the battlefield roles largely mirrored each other. Both had tanks. Both had infantry. Both had artillery. Both played the frontline in similar ways.
Vietnam scraps that entirely. The US Armed Forces and the North Vietnamese Army (NVA) play nothing like each other.
The US side gets helicopters for rapid troop insertion, fire support, and supply drops. They have air mobility that can bypass jungle terrain entirely. Their weapons lean toward heavier firepower and longer range.
The NVA has no helicopters. Instead they get an underground tunnel network they can build and expand. Tunnels move troops unseen, create hidden spawn points, and let NVA squads appear from directions the enemy was not watching. Their weapons and tactics lean toward ambush range — dense jungle, close contact, hit-and-run pressure.
This is the shift that changes how every match feels. In the original game you learn the game, then apply that knowledge to both sides. In Vietnam you learn two different games that share the same map. The US vs NVA breakdown goes deeper on this if you want the full comparison.
New Vehicles: Helicopters and Patrol Boats
The original Hell Let Loose is built around tanks, trucks, artillery guns, and anti-tank weapons. Armor plays a big role. Getting a tank across a contested field with infantry support requires real coordination.
Vietnam keeps some ground vehicles but its headline additions are completely different. The US side gets fully operational UH-1 Huey helicopters for fire support and supply drops. Pilots can insert squads directly into objectives, run resupply routes, provide strafing fire, and act as mobile spawn points in some situations. Helicopters are loud, fast, visible from across the map, and a priority target for the NVA. Flying one well is a whole separate skill set — see the helicopter pilot guide for the details.
Both sides also get patrol boats. Vietnam’s six maps all feature rivers, and those rivers are navigable. Boats let squads flank through waterways the enemy cannot easily cover, deliver supplies to forward positions, and act as mobile spawn points on the water. This kind of river combat simply does not exist in the original. The patrol boats guide covers how they work.
NVA Tunnels Replace Tank Warfare as the Second Big Vehicle System
The original game’s second faction had their own tanks as a counterweight to Allied armor. In Vietnam, the NVA’s equivalent asymmetric tool is the tunnel network.
NVA players can build tunnel entrances and exits across the map. These give their squad fast underground movement between positions, hidden spawn locations that are much harder for US forces to find and destroy than surface garrisons, and the ability to appear behind or beside positions the US thought were secured. A well-built tunnel network changes how an NVA squad defends a sector completely.
This mechanic has no equivalent in the original game. It takes some time to learn properly, both as an NVA player building them and as a US player trying to find and eliminate them. The tunnel guide and how to use tunnels as NVA are worth reading before you dive in.
New Movement System
This is one of the clearest signs Vietnam is not just a reskin. The game adds four movement mechanics that do not exist in the original.
Swimming. Vietnam’s maps are built around rivers. You can now cross water rather than having to find a bridge or boat. This opens up flanking routes and map flow that just were not possible in the original’s European battlefields.
Climbing. Dense jungle and mountain terrain gave the developers reason to add proper climbing. Getting over obstacles, reaching elevated positions, and navigating complex terrain all feel different from the original’s flatter European maps.
Fast crawling. In dense vegetation, moving quickly while staying low and hidden is often more important than standing up and running. Fast crawling lets players move through grass and jungle undergrowth without fully exposing themselves.
Dragging wounded teammates. This is the most tactically interesting addition. When a teammate goes down near an exposed position, you can now drag them to cover before reviving them. In the original, a downed player was either revived where they fell or left for dead. In Vietnam, a Medic who uses the drag mechanic properly can save someone who would otherwise have been impossible to revive safely. See the drag wounded guide for how it works.
New Game Modes
The original Hell Let Loose shipped with Warfare and Offensive. Vietnam keeps both and adds two new modes that were designed specifically for this game.
Conquest spreads five capture points across the map in a cross layout. Both teams can attack any of them at any time. The new Morale system punishes careless deaths — every player who dies and redeploys drains their team’s shared Morale. Lose all your Morale while the enemy holds more points and you lose, though overtime rules add a twist to this. It is the most strategically demanding mode in Vietnam and has no equivalent in the original.
Domination is a faster 30-minute mode focused on three central objectives. Control two of them and the enemy HQ unlocks for assault. Capture the HQ for an instant win, or hold the majority of central points when the timer expires. Unlike Conquest, there is no Morale system here, so deaths carry less additional cost. It plays faster and more chaotically than any mode in the original game.
For a full breakdown of all four modes, the all game modes guide covers them in detail.
Maps: Jungle vs. Europe
The original Hell Let Loose ships with 17 maps based on WWII battlefields — Omaha Beach, Carentan, Stalingrad, Kursk, and others. They are varied in terrain but share a certain visual and tactical language: fields, towns, bridges, forests, ruins, and long approaches across relatively open ground.
Vietnam launches with six maps built around real Vietnam War locations and operations. The terrain is completely different. Dense jungle that breaks sightlines, mountain gorges, river networks, terraced farmland, coastal positions, and urban sectors all appear across the launch roster. You are not reading a map the same way you read a European WWII battlefield. The jungle does not give you the same long sightlines. Enemies can be much closer before you see them.
Six maps is fewer than the original at launch, but the original had years to accumulate its content. Vietnam’s map count will grow with updates. Our all maps guide covers what each one offers and how the terrain affects faction strengths.
Roles and Classes
The original Hell Let Loose has 14 roles. Vietnam ships with 17 across six unit types: Command, Infantry, Recon, Armor, Helicopter (US only), and Mortar Squad.
The helicopter unit type is brand new. Pilot roles did not exist in the original game at all. NVA-exclusive roles around the Anti-Aircraft class also have no equivalent in the original. The mortar squad gets more definition in Vietnam too, with mortar play being more central to how NVA pressure is applied across the wider jungle maps.
Veterans of the original will recognize most roles instantly — Rifleman, Medic, Engineer, Squad Leader, Commander, Sniper all carry over in recognizable form. But the new roles and the new ways they interact with Vietnam’s terrain and faction tools mean the class system feels meaningfully expanded rather than just reskinned. The all classes guide covers every role in Vietnam.
Console Crossplay — A First for the Series
The original Hell Let Loose never supported crossplay between PC and console. PC players and console players were always in separate server pools, even after the console versions launched.
Vietnam changes this completely. Full crossplay between PC (Steam, Epic, Microsoft Store), PlayStation 5, and Xbox Series X|S launched day one on August 13, 2026. All three platforms share the same servers by default. Server owners can configure platform access — full crossplay, PC-only, or console-only — and players filter for their preference in the server browser.
Console players on cross-platform servers get aim assist to help close the gap against mouse-and-keyboard input. This is a significant change for console players who felt isolated from the main PC player pool in the original game. The crossplay guide covers how the whole system works, and if you are playing on controller the controller settings guide has the setup advice you need.
Engine Upgrade: Unreal Engine 5
The original Hell Let Loose runs on Unreal Engine 4. Vietnam switches to Unreal Engine 5. In practice this means better visual fidelity, more detailed foliage and terrain, improved lighting, and the ability to support the denser, more complex jungle environments that Vietnam requires.
On console, both PS5 and Xbox Series X|S target 60 frames per second using Dynamic Resolution Scaling to maintain that frame rate during heavy 50v50 moments. PC players can push higher depending on their hardware, with support for DLSS 4.5 with Frame Generation on Nvidia cards and TSR on AMD.
The engine change also enabled new interaction systems — the swimming, climbing, fast crawling, and drag mechanics mentioned earlier — that would have been harder to implement cleanly in UE4.
What the Original Still Does Better
Vietnam is the newer game but it is not better in every way, at least not yet.
The original Hell Let Loose has 17 maps against Vietnam’s 6. That is years of content that Vietnam will take time to match. The original game is also more heavily documented — guides, tutorials, community knowledge, and meta understanding are all more developed after years of play. New players who want to learn the game with maximum available support are still better served starting with the original.
The original’s tank warfare is also deeper. If you love the combined-arms armor gameplay of WWII — crew management, hull-down positions, coordinating infantry support for an armor push — Vietnam’s vehicle system does not replicate that. Helicopters and boats create their own appeal but they are not the same as a Panther or a Sherman rolling across a contested field.
Should You Play Both or Choose One?
They are different enough that both are worth playing if you enjoy the genre. The original is the better learning environment and the richer content library right now. Vietnam is the more exciting thing to be playing at this moment in the game’s life.
If you are completely new to Hell Let Loose, starting with the original is still the smarter move. The core systems are easier to learn against a background of more community knowledge, more tutorials, and more established player behavior. Once you understand garrisons, supply nodes, chain of command, and sector flow, Vietnam will feel familiar from the first match rather than overwhelming.
If you are a veteran of the original, Vietnam is worth the separate purchase. The two new game modes, the asymmetric faction play, the helicopter system, and the tunnel network all give you genuinely new things to learn. The jungle maps play completely differently from anything in the original roster. It is not just a coat of paint.
