Arc Raiders Patch 1.12.0 Cleans Up Major Exploits

The extraction shooter Arc Raiders has received a focused new update, patch 1.12.0, aimed squarely at restoring fairness and tightening up the game’s competitive integrity. While it is not a huge content drop, the changes it introduces are highly targeted: fixing two major duplication exploits, addressing a notorious out-of-bounds route on Stella Montis, and resolving situations where players could deal damage through solid map geometry.

This article breaks down exactly what the patch changes, why these fixes matter so much for an extraction-focused shooter, and what players can realistically expect from Arc Raiders in the short term after the update.

Why This Patch Matters for an Extraction Shooter

Extraction shooters live and die on a delicate balance of risk, reward, and trust. Every raid is supposed to feel like a high-stakes gamble: you invest time, gear, and skill with a chance to walk away with valuable loot. When exploits disrupt that loop, the entire experience starts to feel pointless.

Patch 1.12.0 is important because it directly tackles problems that undermine that core experience:

• Duplication exploits flooded the economy with illegitimate gear and ammo.
• Out-of-bounds positions gave cheaters near-invulnerable angles with no realistic counterplay.
• Damage-through-geometry bugs made cover unreliable and created situations that felt like outright cheating.

By closing these loopholes, Embark Studios is reinforcing the idea that your decisions and skill, not your willingness to abuse a glitch, should determine the outcome of a raid.

Overview of Arc Raiders Patch 1.12.0

On paper, the 1.12.0 patch notes are brief, but the impact of each line is significant. At a high level, the update includes:

• Removal of an item duplication exploit.
• Removal of an ammo duplication exploit.
• Fixes for damage from behind map geometry in certain scenarios.
• Corrections for out-of-bounds map locations on the Stella Montis map.

There are no sweeping weapon balance changes or large new features in this patch. Instead, it is what developers often call a “cleanup” or “maintenance” update: a targeted effort to remove ways of bending the game in directions it was never designed to go.

At-a-Glance Patch Summary

Item Duplication Exploits and the Health of the Loot Economy

One of the headline changes in patch 1.12.0 is the removal of an item duplication exploit. While specifics are not documented in detail, the exploit allowed players to generate multiple copies of items that were meant to be scarce.

How Duplication Breaks Progression

In an extraction shooter, the value of items is rooted in their scarcity and the risk you take to obtain them. Duplication glitches cut directly against that design. When some players can duplicate gear at will:

• Rare items no longer feel special or hard-earned.
• Legitimate players are pressured to either exploit as well or fall behind.
• The in-game economy becomes distorted, especially in any trading or stash systems.

Game developers across the industry treat duplication bugs as critical issues for this reason. For example, Bungie has repeatedly rushed hotfixes to Destiny 2 when crafting or currency duplication appeared because it can crash the game’s entire reward structure if left unchecked.¹

What the Fix Means for Players

With the item dupe now closed off, Arc Raiders returns to a more grounded progression curve. Players who avoided abusing the bug should feel like their time investment is finally on a level playing field with everyone else.

If you were tempted by duplication exploits but avoided them, this patch vindicates that choice. If you relied on the exploit, you will likely experience a short-term adjustment as you adapt to playing within the intended economy, but long-term, the game’s sense of achievement should feel stronger.

Ammo Duplication and the Importance of Scarcity in Combat

The patch also addresses a separate ammo duplication exploit. Infinite or nearly infinite ammunition fundamentally changes how players approach fights.

Why Ammo Management Matters

Designers of tactical and extraction shooters often impose meaningful limits on ammo to encourage decision-making and create tension. Scarce ammo forces players to:

• Choose when to engage and when to avoid conflict.
• Swap between weapons based on remaining rounds.
• Value supply crates and resupply points during a raid.

Research into game balance and player engagement suggests that well-tuned constraints (like limited resources) can increase immersion and satisfaction by making success feel earned rather than inevitable.² An ammo duplication bug breaks that constraint completely.

Expected Impact of the Ammo Fix

With the duplication fix in place, players can no longer rely on essentially limitless ammunition to brute-force encounters. This should lead to:

• More cautious pushes into hot areas.
• Greater importance placed on sound, positioning, and teamwork.
• Higher tension late in raids when ammo reserves run low.

For players who never took advantage of the exploit, the main benefit is that fights will feel more predictable and fair: you will know that enemies are bound by roughly the same resource limits as you are.

Fixing Damage from Behind Map Geometry

Another notable improvement in patch 1.12.0 is the correction of situations where players could damage others from behind geometry. In practice, this meant you could be hit by gunfire or abilities even while visually behind cover or solid terrain.

Why Reliable Cover Is Critical

Reliable cover is foundational in any shooter that emphasizes positional play. When the game tells you that an object is solid and protective, but bullets still land through it, trust in the game breaks. Competitive shooters like Valorant and CS2 devote significant effort to ensuring that hit registration and line-of-sight calculations align closely with what players see on screen, because desynchronization is a major source of frustration and perceived unfairness.³

What Changed with the Geometry Fix

While the patch notes only mention that “some cases” of this problem have been fixed, that alone is a big quality-of-life improvement. The fix likely involved:

• Adjusting collision meshes for certain objects and walls.
• Tightening up how bullets or projectiles trace line-of-sight.
• Removing unintended micro-gaps that allowed shots to slip through.

Practically, players should now be able to trust their cover more often. If you position smartly and respect angles, you are less likely to be randomly shredded by shots that appear to be passing through solid terrain.

Stella Montis Out-of-Bounds Routes Finally Closed

The most infamous change in this patch concerns the Stella Montis area, where players discovered ways to reach out-of-bounds positions and gain massive unfair advantages.

How Out-of-Bounds Exploits Shape a Map

When players slip outside of the intended playable space, several problems arise:

• They may gain high ground or sight lines that were never balanced for combat.
• They can often shoot into the map while being nearly impossible to shoot back.
• Spawn routes, extraction points, and loot locations can be camped with impunity.

From a level design perspective, these exploits bypass all of the purposeful constraints that shape a map’s flow.⁴ Instead of moving through lanes, cover, and chokepoints, exploiters operate from angles the designers never accounted for.

Closing the Stella Montis Loopholes

Patch 1.12.0 mentions fixing “various out-of-bounds map locations” on Stella Montis, suggesting multiple routes or spots were plugged. Common ways developers address such issues include:

• Raising invisible walls or adjusting collision volumes.
• Adding kill zones or countdown timers if players move into forbidden areas.
• Rebuilding bits of terrain so that previously abusable geometry no longer provides footholds.

For players who were repeatedly ambushed from impossible angles, this should be a major relief. Encounters on Stella Montis will now be more predictable and tactical, rather than hinging on whether someone discovered a new out-of-map perch.

Community Reaction: Mixed Feelings, Clear Benefits

Player reactions to targeted patches like this often fall into two broad camps:

• Supportive players who value fairness are pleased to see exploits removed, even in a small patch.
• Content-hungry players might feel underwhelmed, wishing there were new guns, enemies, or quests alongside the fixes.

Both perspectives are understandable, but there is a strong argument that fixes like these should be prioritized. Competitive multiplayer games routinely deploy small, focused patches to protect gameplay integrity between larger content drops. For example, Riot Games pushes frequent balance and bug-fix updates in League of Legends and Valorant between major seasonal releases to keep the experience healthy.⁵

In the case of Arc Raiders, patch 1.12.0 is very much in that spirit: a short, surgical update aimed at keeping the foundation solid so future content lands on stable ground.

What Players Should Do After Updating

If you are returning to Arc Raiders or continuing to play through patch 1.12.0, there are a few simple steps to get the most out of the update:

• Restart your client to ensure the update is fully installed and loaded.
• Reassess your loadouts with the assumption that ammo is now finite and must be managed carefully.
• Re-learn Stella Montis with the understanding that previously abusable spots are gone.
• Practice using cover more aggressively, since damage-through-geometry incidents should be rarer.

It may also be worth revisiting strategies or guides that relied on the old exploits; many of those tactics will now actively harm your performance or get you caught out in exposed positions.

Looking Ahead: The Role of Maintenance Patches

Although patch 1.12.0 is relatively small, it signals something important about Embark Studios’ priorities: a willingness to move quickly on issues that weaken the game’s competitive and cooperative experience. For a live-service game, that mindset is essential.

Going forward, players can reasonably hope for a rhythm that alternates between:

• Maintenance patches like this one, focused on exploits, bugs, and map flaws.
• Feature or content updates that bring new weapons, enemies, modes, or progression paths.

If that cadence is maintained, Arc Raiders stands a good chance of building long-term trust with its community: players know that their time investment is safe from rampant exploits, and that the developers are watching closely enough to respond when problems emerge.

Frequently Asked Questions

Does patch 1.12.0 include weapon balance changes?

No. Based on the publicly available patch notes, 1.12.0 is focused on exploits and map issues. Weapon stats, recoil patterns, and damage values appear unchanged in this update.

Are all duplication exploits gone?

The patch specifically mentions one item duplication exploit and one ammo duplication exploit. Those particular methods should no longer work. As with any live game, new bugs may surface in the future, but these known exploits have been addressed.

Can players still get out of bounds on Stella Montis?

The patch notes state that “various” out-of-bounds locations have been fixed. That suggests multiple routes were closed, but it does not guarantee that every possible exploit is gone forever. If new issues are found, reporting them through official channels increases the odds they will be patched quickly.

Will legitimate players be punished for past use of these exploits?

The patch notes do not mention bans or retroactive penalties. In many online games, developers reserve punishments for extreme or repeated abuse, but the specific enforcement policy is up to Embark and may evolve over time.

What should I do if I still encounter damage through walls or cover?

If you continue to see suspicious damage-through-geometry situations after the patch, capturing video or screenshots and submitting a bug report to the developers is the best course of action. Detailed reports help them reproduce and fix remaining edge cases.
