This update expands your arsenal like never before. The Armoury Update introduces five brand-new weapons, a deadly new ammunition type, and a host of quality-of-life features designed to make every raid smoother and deadlier. We’ve also made tweaks to NPC behaviour, recoil, and world systems to ensure firefights feel sharper and more immersive.
The Zone just got a whole lot louder. Five fresh firearms join the fight, each bringing unique firepower and tactical depth:
A semi-automatic shotgun with blistering stopping power. Devastating at close range and perfect for clearing corridors, the Paiga-12 offers serious crowd-control with every trigger pull.
This modular rifle combines precision and flexibility. Chambered in 5.56mm, it’s designed for mid-to-long-range engagements, offering versatility in raids where reliability is key. Alternatively, run the more compact 9x19mm version! This SMG-calibre rifle trades stopping power for controllability and ammo efficiency, a great choice for fast-paced, close-quarters encounters.
Built for speed and mobility, the NP9 is a lightweight SMG perfect for aggressive pushes or as a trusty backup when things get tight. Or give the heavier-hitting cousin of the NP9, chambered in .45 ACP a go instead! It sacrifices some fire rate for raw damage per shot, rewarding steady aim with brutal stopping power.
A new round designed to shred through armour. When regular buckshot won’t cut it, AP Buckshot ensures no target feels safe behind protection.
Fire Mode Icon: A new HUD icon makes it clear which fire mode you’ve selected — no more guessing in the heat of combat.
Quick Attachment Handling: Attach or detach scopes, silencers, magazines, lasers/torches, and foregrips directly without opening the modding menu (only when the weapon is not equipped). You can do this anywhere! So both in the bunker and when out on a raid, so keep an eye on enemy attachments, because now they're up for grabs!
Inventory & PDA:
New option to auto-close Inventory when hit.
New option to auto-close PDA when hit.
Storage Base: Renamed single-use storage base for clarity.
Recoil Adjustments: All SMGs now have reduced recoil, making them more stable in firefights.
Healing Confirmation: Setting added to remove confirmation before healing from Doctor.
NPCs will no longer shoot at you from outside the visible screen.
High-tier NPCs wielding automatic rifles now fire closer to their weapon’s true rate of fire, making them deadlier and more realistic opponents.
Slightly increased the chance of Emissions occurring in the Zone.

Stash page names may not update correctly.
Inventory highlights sometimes display incorrectly.
Unable to mod loadouts #2 or #6.
