Arc Raiders Patch Targets Stella Montis Glitches

Embark Studios has deployed update 1.12.0 for its extraction shooter Arc Raiders, aiming to eliminate notorious out-of-bounds exploits on the Stella Montis map. The developer's community lead, Ossen, published full patch notes on January 20, detailing a focused set of fixes for the massively popular title.

While the update targets several critical issues, including item duplication and damage-from-behind-geometry bugs, the community response has been mixed. Players are already reporting that the infamous "wall glitch" remains active, suggesting the patch may have only addressed a fraction of the problem.

The January 20 adjustments were specifically designed to curb exploitative behavior that has plagued the game since launch. According to the official release, update 1.12.0 addresses three primary categories of exploits that were giving unfair advantages to players.

The targeted fixes include:

• Item duplication exploit patched
• Ammo duplication exploit resolved
• Damage from behind certain geometry fixed
• Various out-of-bounds locations on Stella Montis addressed

Notably, the patch notes specify that "various" out-of-bounds locations were fixed, rather than claiming all such exploits were eliminated. This careful wording suggests the developers are aware of the complexity involved in completely sealing the game's geometry.

Despite the developer's efforts, Discord users and Reddit players began reporting issues almost immediately after the patch went live across PC, PlayStation 5, and Xbox Series X | S. The cold, labyrinthian halls of Stella Montis have already garnered a reputation as the most cutthroat topside area, and its abundance of cheaters isn't helping.

Player reports paint a picture of persistent problems:

"There is still a wall glitch in Stella (somewhere in the lobby area). Embark is incapable of fixing their game."

"So, I guess they didn't fix wall glitches because I just got killed by 3 people inside the seed vault extract in Stella."

"This patch notes seems like it only attracted rats into walls on Stella."

The dissatisfaction stems from a pattern of incomplete fixes. A previous December 11 patch was supposed to tackle an out-of-bounds glitch related to zipline use on Stella Montis, yet players continued encountering cheaters weeks later. Now, reports of wall exploits have expanded to include Dam Battlegrounds and Spaceport, with an unopenable door in Stella Montis adding to the growing list of technical issues.

Embark Studios appears to be taking a phased approach to the anti-cheat battle. Earlier this month, the developer shared that out-of-bounds glitches had been added to a list of anti-cheat fixes slated for implementation "over the next few weeks." This suggests update 1.12.0 may be just the first step in a larger, more comprehensive plan.

Some community members are showing patience, recognizing the technical challenges involved. One Reddit user argued, "I don't know much about game design, but I'm sure it takes a while to find and fix problems within coding. So I think people should be happy that they've fixed the exploits that have been such a source of complaints for so long."

The game's recent history provides context for this ongoing struggle. Arc Raiders launched on October 30, 2025, with the Stella Montis map introduced on November 13. The Cold Snap event followed on December 16, showing the studio's commitment to regular content updates even as they battle technical issues.

The issue extends beyond simple glitches into the realm of active cheating. Streamers and everyday Raiders alike have reported dying to cheaters on the high-difficulty map for months, with the out-of-bounds exploit proving especially problematic. The ability to damage other players from behind certain geometry has been a particular point of frustration.

One widely shared clip demonstrated how the glitch has been used to steal some of the best loot from players attempting to extract back to Speranza or even just play music. The community's patience has worn thin as these exploits have persisted through multiple update cycles.

In a twist of irony, two content creators have found themselves caught in the line of fire of Embark's anti-cheat efforts, though details on these specific cases remain limited. The studio's challenge is clear: maintain the integrity of the game while continuing to deliver new content and events.

The battle against exploits in Arc Raiders is far from over. While update 1.12.0 represents a concrete step toward addressing the infamous Stella Montis glitches, the immediate player reports suggest the problem runs deeper than a single patch can solve. Embark Studios' acknowledgment that fixes will roll out over "the next few weeks" indicates this is an ongoing process rather than a one-time solution.

For now, players navigating the cold corridors of Stella Montis must remain vigilant against "rats in the walls" while the developer continues its work. The extraction shooter community has shown both frustration and understanding, recognizing that complex game development challenges require time and sustained effort. As Embark Studios continues to implement its anti-cheat roadmap, the true measure of success will be whether future updates finally seal the doors against these persistent exploits.
