The High Capacity GP3A Magazine is in a backpack inside the ruined building at Kazkovyi Camp in the Burnt Forest; climb through the anomaly-filled interior, use the upper balconies to reach the blocked room, and loot the backpack on the shelf.
Update 2.0 dropped the GP3A designated marksman rifle into the Zone, and if you want it holding more rounds between reloads, the High Capacity GP3A Magazine is the attachment to grab. It isn’t sold in a shop or handed out as a quest reward — it’s tucked inside a backpack in a wrecked, anomaly-choked building at Kazkovyi Camp, out in the Burnt Forest west of the Lesser Zone. Getting to it means climbing through a floor full of things that will kill you, so the route matters as much as the map marker.

The pickup is a single fixed spot: a two-story brick building at Kazkovyi Camp. Cross the bridge out of the Lesser Zone, run west into the Burnt Forest, and make for that house — the magazine is in a backpack resting low on a wooden shelf in one of the upper rooms. Here’s everything the loot screen shows when you open it.
How to reach the backpack inside the Kazkovyi Camp building
Key The corridors inside are blocked, so the real path threads through anomalies and out across the balconies — follow this movement and you’ll land at the backpack without dying on the floor.
STEP 1/5
Set your marker for Kazkovyi Camp
Open the PDA map and travel to Kazkovyi Camp in the Burnt Forest, west of the Lesser Zone, then head to the two-story brick building.
STEP 2/5
Head left and jump inside
Enter the ground floor, go left, and jump past the first hazard as you start working toward the upper level.
STEP 3/5
Crouch across to the far side
Crouch under the electrical sparks, move to the other side of the room, and crouch again to slip through the gap.
STEP 4/5
Jump the balcony gap
Step out onto the balcony, jump across the broken section to the next balcony, and crouch back inside to reach the blocked corner room.
STEP 5/5
Open the backpack on the shelf
Find the yellow-trimmed backpack on the wooden shelf and take the High Capacity GP3A Magazine.
Crouch through every anomaly gap and jump the balconies instead of hunting for an interior door — the corridors are blocked, and the electrical and gas anomalies will drop you fast if you walk through them upright.

Route hazards and the spot players miss
This is not a walk through a front door. The interior corridors are sealed off, so the intended path pushes you out onto exterior balconies and back in through openings — if you keep looking for a normal doorway, you’ll circle the ground floor and give up. The bigger threat is what’s on the floor: the building is laced with electrical arcs and pockets of toxic gas that can put you down in seconds, which is why every tight spot rewards a crouch and a little patience over speed.
The payoff is also easy to walk straight past. The backpack sits low on a wooden shelf in the final corner room rather than on a body or a countertop, so sweep the floor level of that last room before you assume you’ve missed it.
How the magazine ties to the GP3A rifle
The GP3A is one of four new firearms Update 2.0 added on August 20, 2026 — a designated marksman rifle that sits between the assault rifles and the full snipers, built for controlled shots at range. This high-capacity magazine is a straightforward upgrade for it, letting the DMR hold more rounds before you have to reload mid-fight. You don’t need the rifle in hand to grab the magazine, so it’s worth stashing from Kazkovyi Camp even before you track the gun down elsewhere in the Zone.

Frequently Asked Questions
Do you need the Cost of Hope expansion to get the High Capacity GP3A Magazine?
No. Update 2.0: Back to the Zone arrived free for every owner on August 20, 2026, and both the GP3A and its high-capacity magazine are part of that free update rather than the paid Cost of Hope expansion that launched alongside it. As long as the game is updated, the Kazkovyi Camp backpack is there for you.
Where do you find the GP3A rifle itself?
The rifle is a fixed world pickup on the roof of the ISF building — not a merchant purchase or a random drop — and it comes with a 4x scope already fitted. The exact story progress or zone access needed to reach that rooftop isn’t fully spelled out yet, so treat it as a spot you’ll unlock as you push through the area rather than one you can head straight to.
