Arc Raiders Update Targets Infamous Stella Montis Glitch – But Some Say ‘Rats’ Are Still in the Walls

Developer Embark Studios says Arc Raiders update 1.12.0 patched some infamous out-of-bounds exploits – but players say “rats” still live in the walls of Stella Montis.

Community lead Ossen took to the official website to publish full patch notes for the January 20 adjustments, revealing a smaller set of targeted fixes for the massively popular extraction shooter. Exploits are in the line of fire this time, with the update said to fix glitches related to item and ammo duplication, the ability to damage other players from behind certain geometry, and a bug that let players reach out-of-bounds locations – specifically on Stella Montis.

The cold, labyrinthian halls of Stella Montis have already garnered a reputation for being perhaps the most cutthroat topside area Arc Raiders has to offer, and its abundance of cheaters isn’t helping. Streamers and everyday Raiders alike have reported dying to cheaters on the high-difficulty map for some time, with the out-of-bounds exploit proving to be especially problematic for months. The clip (above) showcases how the glitch has been used to steal some of the best Arc Raiders loot from players who are looking to extract back to Speranza or even just play some music.

Finally, update 1.12.0 is here to take care of what is maybe Embark’s most infamous exploit, but it sounds like it’s more of a speed bump than a stop sign. Just as the patch made its way to players across PC, PlayStation 5, and Xbox Series X | S, Discord users began to report they were still losing runs to Raiders behind walls in Stella Montis. The developer’s patch notes do say that “various” – and not necessarily all – out-of-bounds map locations had been addressed, but that isn’t stopping fans from expressing their disappointment.

“There is still a wall glitch in Stella (somewhere in the lobby area),” one Discord user said. “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 Montis,” another added.

“This patch notes seems like it only attracted rats into walls on Stella,” another player said.

Disattisfaction with the update seems to stem from a December 11 patch, which was said to have tackled an out-of-bounds glitch related to zipline use on Stella Montis, only for players to find themselves still dealing with cheaters weeks later. Players have also shared reports of wall exploits at Dam Battlegrounds and Spaceport, with an ongoing issue related to an unopenable door in Stella Montis adding to the pile of glitches riling up the community.

Embark shared earlier this month that out-of-bounds glitches had been added to a list of anti-cheat fixes it hoped to implement “over the next few weeks,” suggesting update 1.12.0 may be just one step in a larger plan. While players have waited weeks for exploit fixes, and Stella Montis may have a few holes to fill yet, some say they’re willing to give the studio more time to get Arc Raiders into shape.

“I don’t know much about game design, but I’m sure it takes a while to find and fix problems within coding,” one Reddit user argues. “So I think people should be happy that they’ve fixed the exploits that have been such a source of complaints for so long.”

Arc Raiders launched October 30, 2025, for PC, PS5, and Xbox Series X | S. Recent content updates include the introduction of Stella Montis November 13, as well as the limited-time Cold Snap event December 16. While streamers and PvP fans both battle cheaters on and off stream, two content creators have (temporarily) found themselves caught in the line of fire of Embark’s anti-cheat efforts. We’ll have to wait and see just how long it takes for the studio to get wall exploits – and cheaters as a whole – under control.
