Game Mechanics
HLL: Vietnam is built on layered, interlocking mechanics — suppression, tunnel networks, asymmetric faction abilities. Understanding them is the difference between average and elite play.
Suppression System
How suppression works in Hell Let Loose: Vietnam. Even bullets that miss pin you in place — making machine gunners one of the most powerful classes in the game.
Tunnel Warfare
The NVA's signature asymmetric mechanic. Build underground tunnel networks for surprise attacks, hidden spawn infrastructure, and repositioning behind enemy lines. Confirmed mechanics from the closed beta — build radius, cooldowns, team limits, and tactical doctrine.
Helicopter Operations
US-only aerial mobility in Hell Let Loose: Vietnam. Full confirmed mechanics from the closed beta — M60D door guns, damage zones, in-air spawning, 3D tactical map, and tactical doctrine for pilots and ground squads.
Patrol Boat Combat
River warfare in HLL: Vietnam. Both factions can deploy heavily armed patrol boats — including PBR-style craft with mounted weapons.
Game Modes
Hell Let Loose: Vietnam launches with 6 distinct game modes across 19 roles and 6 maps. Warfare and Offensive return from the original game; four brand-new modes designed around Vietnam's helicopters, tunnels, and river networks complete the lineup.
Vehicle Seat Selection
A confirmed new QoL feature — a selection wheel lets you pick your vehicle seat before boarding, replacing the old swap-seats-after-entry system.
Movement & Swimming
Hell Let Loose: Vietnam introduces the most extensive player movement system in the franchise's history. Swimming, climbing, fast crawling, dragging wounded allies, and underwater diving — all confirmed mechanics that change how the jungle and river maps play.
Equipment & Weight System
A new loadout system for Hell Let Loose: Vietnam. Every item you carry has a weight value — exceeding your carry capacity slows you down. Build loadouts that balance firepower, utility, and mobility for your role and playstyle.
Equipment & Items
Every deployable, tool, and consumable item confirmed in Hell Let Loose: Vietnam — from bandages and morphine to claymores, tripwires, AA guns, and repair stations. What each item does, which roles carry it, and how it fits into the weight system.
Commander Abilities
Every confirmed Commander ability in Hell Let Loose: Vietnam — US and NVA strikes, reinforcements, supply drops, and vehicle calls. When to use each, what it costs, and how to time them for maximum effect.
Spawn Infrastructure
How spawn points work in Hell Let Loose: Vietnam — Garrisons, Outposts, NVA tunnels, patrol boat radios, and the Airhead. The complete guide to keeping your team in the fight and denying the enemy theirs.
