New Additions & Highlights
The Spring 2026 Update delivers one of the most substantial content and gameplay overhauls yet. Operation: Deep Freeze expands the ongoing narrative with a frozen battlefield, a deadly boss encounter, a Mire enemy type, a returning specialist, two weapons, and dual-wield variants for the Commando Sentinel and Engineer Krait. The update also introduces the highly requested Long Game Length option, refined and more accurate bash mechanics, a streamlined Skip to VTOL match start, mutation waves, and weekly mutators. Alongside the content drop comes major combat tuning to make encounters faster and deadlier, extensive weapon and grenade rebalancing, expanded quality-of-life improvements, and a sweeping stability and polish pass addressing hundreds of issues across gameplay, AI, UI, networking, and performance.
New Operation: Deep Freeze
Nightfall’s hunt for Dr. Moorcroft takes a dangerous turn when a lone mercenary pursuing the same target forces an uneasy alliance. As tensions rise, the team discovers Moorcroft is building an army from another dimension. If he succeeds, containment may no longer be possible.
Operation: Deep Freeze contains seven new missions across familiar maps and the new Arctic map. Completing the missions will unlock exclusive player cards, character skins, weapon trinkets, and XP rewards.
New Specialist: Masterson
The original mercenary returns.
Masterson joins the roster as a playable character, bringing classic attitude, veteran presence, and unmistakably British energy back to the front lines.
New Map: Antarctic Base
A frozen research facility at the edge of the world becomes the latest battleground. Tight corridors, exterior snowfields, and high-tech interiors create varied combat spaces in one of Nightfall’s most hostile environments yet.
New Game Length: Long (10 Waves)
Long mode consists of ten waves and is designed to feel more epic and progression-driven than the five-wave format. Combat pacing, resource management, and team coordination become increasingly important as matches extend deeper into late-wave pressure.
New Boss: Alpha Scavenger
Dr. Emmanuel Moorcroft found this endemic species while conducting research expeditions within the enigmatic Dreadzone. He opened a Mire portal to transport this large, ferocious creature to our world, integrating it into his own personal fighting force.
New Enemy: Scavenger
Spawned from the void between worlds, these otherworldly arthropods are deeply suffused with the Mire, granting them exceptional speed and lethal adaptability in the hunt.
New Weapon: Tekko Kagi (Ninja)
A dual-claw melee weapon focused on speed, affliction control, and close-quarters dominance.
