Hell Let Loose: Vietnam Update 1.5 Adds Licensed Huey and New Weapons

Update 1.5 for Hell Let Loose: Vietnam, published 15 September and launching 16 September, marks the game's first significant content expansion since release. The headline addition is the officially licensed Bell UH-1 Iroquois — the 'Huey' — which replaces the game's existing fictional helicopter model rather than sitting alongside it.

What changed

Helicopter overhaul

• The licensed Huey replaces the previous fictional helicopter, bringing balancing changes alongside the model swap
• New HUD icons let pilots and co-pilots communicate Supply Drop, Spawning, Auto Levelling, Cockpit Radio, and Repair/Resupply status
• M60 ammunition upgraded: AP rounds now damage boats and tunnels, tracer count increased, and capacity raised from 400 to 500 rounds
• A cockpit audio alarm now triggers when hull health runs low
• Destroyed helicopters no longer kill occupants instantly — the aircraft crashes to the ground before destruction

New weapons

• M14 and Type 56 SKS added to loadouts
• A first balancing pass applied to the launch weapon arsenal

Broader improvements

• Further refinements to Commander Orders, spawning, and the Tactical Map
• 100+ fixes and quality-of-life improvements across the game

For players who found the original helicopter model a visual mismatch with the licensed Huey's cultural weight, the swap alone signals a maturing of the game's authenticity — and the crash sequence change meaningfully alters the risk calculus for crews.
