ARC Raiders Dupe Glitch Explained

The duplication exploit problem in ARC Raiders has gotten bad enough that Embark Studios published a blog post with detection graphs to show players they are watching. The most recent offender, the 'stack split' exploit, was patched on July 9, 2026, but the damage to the in-game economy was already done. Here's everything you need to know about how the glitch worked, why it mattered, and what Embark is doing to players who used it.

How did the ARC Raiders stack split dupe glitch work?

The stack split exploit was frustrating precisely because it required zero technical skill. Any player on PC, Xbox, or PS5 could pull it off in seconds using nothing but their inventory screen.

Here's the exact sequence that triggered it:

1. Prepare a stack of items in your inventory.
2. Drag exactly half the stack onto the ground, dropping it.
3. Move the remaining half-stack to a different slot in your backpack.
4. Watch the dropped stack on the floor multiply.
5. That's the whole thing. No mods, no exploited menus, no external tools. The simplicity is what made it spread so fast across all platforms. Players would walk through ARC Raiders' maps and see others openly running the exploit mid-raid, which tells you how confident people felt doing it.

Can you get banned for duping in ARC Raiders?

Yes, and the odds are high that you will be. Embark Studios operates with what they describe as billions of data points on player behavior at any given moment. Every item interaction, every inventory movement, every drop is logged. Detecting a duplication pattern in that data is not a complex task for a team with that level of telemetry.

Embark published a blog post (linked from their official site at arcraiders.com) that included a graph specifically showing how they identify duping behavior. They did not publish that graph to inform players how detection works. They published it to make clear that they already know.

Players across social media have reported receiving permanent bans for using duplication exploits. Not temporary suspensions. Permanent removals.
