The search query glitch through door arc raider refers to a highly publicized issue in ARC Raiders where players were able to bypass locked doors or appeared to move through closed doors during PvP encounters.
This topic has been widely discussed across Reddit, Steam, YouTube, and gaming press coverage. However, most explanations fail to distinguish between three separate issues:
- A confirmed locked door collision exploit
- Network replication desync
- Animation and collision timing mismatch
Only one of these was an actual exploit.
This article separates them clearly, explains the technical mechanisms involved, analyzes Patch 1.4.0 in detail, and clarifies the current state of the issue.
What the Original Door Exploit Actually Was
The original issue behind glitch through door arc raider involved bypassing locked rooms without using a keycard.
Locked rooms in ARC Raiders are designed to:
- Gate high tier loot
- Create risk reward tension
- Incentivize keycard acquisition
- Funnel PvP pressure
The exploit leveraged a collision flaw in certain door geometries. Under specific physical interactions, a player capsule could clip through the collision boundary of a locked door.
Important characteristics:
- Occurred on certain door types only
- Required precise positioning
- More reliable in narrow interior spaces
- Amplified when player bodies applied pressure from specific angles
This allowed entry into locked loot rooms without key validation.
This was not visual lag.
This was a geometry flaw.
Why This Exploit Was Structurally Damaging
The impact extended beyond simple clipping.
It disrupted:
Loot Economy
High tier rooms were accessed without consuming keycards.
Risk Calibration
Players avoided exposure during unlock animations.
PvP Timing
Hotspots shifted unpredictably.
Keycard Value
Temporary devaluation within the progression system in ARC Raiders since legitimate access was bypassable.
In extraction shooters, gating mechanics control raid pacing.
When bypassed, the entire reward structure destabilizes.
Coverage of the door glitch method detailed how players were abusing this flaw before it was addressed.

How Door Interaction Actually Works
Understanding this removes most confusion around glitch through door arc raider.
Door lifecycle in simplified form:
- Player sends interaction request
- Server validates action
- Server updates door state
- Server updates collision
- Animation replicates to clients
The server controls collision.
The client displays animation.
These two processes are not perfectly simultaneous.
Under normal latency they appear synchronized.
Under delay, collision may update before animation reflects it visually.
This explains most modern reports.
Door Desync Is Not the Exploit
Most current “glitch through door” complaints are desync.
What you see:
- Door appears closed
- Enemy walks through
What actually happened:
- Server already registered door open
- Collision removed server side
- Your client had not updated animation yet
This is replication delay, not cheating.
Desync becomes visible under:
- High ping
- Packet instability
- Temporary server load
- Simultaneous multi client interactions
This is inherent to server authoritative multiplayer systems.
Animation and Collision Timing Mismatch
Doors have two separate systems:
- Visual animation
- Collision state
If collision disables slightly before animation finishes:
- You see a player entering during the final animation frames
- It looks like phasing
This is a sequencing issue.
It does not allow bypass of locked rooms.
Patch 1.4.0 What Was Actually Fixed
Patch 1.4.0 addressed the exploit in two primary ways.
Collision Adjustments
Door geometry and boundaries were refined to reduce clipping windows.
Environmental Deterrent System
Flamethrower traps were added inside certain locked rooms.
Purpose:
- Punish unauthorized entry
- Discourage exploit attempts
- Rapidly mitigate abuse
This was a live service containment strategy.
A full door system rewrite mid season risks destabilizing broader interaction systems.
Deterrence provided fast protection.
Does the Glitch Still Work Today
As of the current patch cycle:
The original locked door collision exploit has been mitigated.
Unauthorized entry into locked rooms triggers environmental punishment systems.
However:
- Desync remains possible
- Animation mismatch remains possible
Those are network timing issues, not exploit mechanics.
Map Geometry Sensitivity
Not all doors behaved equally.
Higher vulnerability perception occurred in:
- Tight interior corridors
- Narrow hinge offsets
- Thin collision margins
- High traffic key rooms
Maps with dense indoor sections such as the Stella Montis map amplified visual clipping perception due to constrained spatial geometry.
Geometry density increases visual ambiguity.
It does not mean the exploit is still active.
How to Diagnose What You Experienced
Before assuming exploit, evaluate:
Likely Exploit
- No keycard used
- Full locked room access achieved
- Repeatable in same location
- No deterrent damage triggered
Likely Desync
- Ping spike observed
- Teammate saw door open normally
- Enemy animation aligned with open state
The Likely Animation Timing Issue
- Occurred during door opening animation
- Not repeatable
- Collision responded normally afterward
Proper classification prevents misinformation.
Defensive Counterplay
Even post patch, intelligent positioning matters.
Avoid:
- Standing flush to hinge side
- Trusting door visuals completely
- Using closed doors as guaranteed cover
Instead:
- Maintain slight offset angle
- Pre aim center door mass
- Expect slight replication delay
- Avoid vertical alignment with hinge
Treat doors as transitional space, not absolute cover.
Struggling with high-risk PvP zones?
Exploit vs Desync vs Cheat Clarified
Precision matters.
| Type | Cause | Intent | Current Status |
| Exploit | Geometry flaw | Intentional | Mitigated |
| Desync | Network delay | Unintentional | Possible |
| Cheat | External software | Intentional | Separate system |
Most modern glitch through door arc raider reports fall into the desync category.
Why This Issue Felt Bigger Than It Was
The exploit felt catastrophic because:
- It invalidated gated loot rooms
- It undermined trust
- It spread rapidly across social media
But mechanically:
- It was limited to specific geometries
- It did not affect every door
- It required precise conditions
Scope matters.
Could It Return
Live service environments evolve.
Risk factors include:
- New map geometry
- Collision mesh updates
- Character capsule adjustments
- Engine interaction changes
Door systems are sensitive networked objects.
Monitoring patch notes remains important.
Final Answer
If you searched glitch through door arc raider, here is the direct answer:
The original locked door exploit existed and was mitigated in Patch 1.4.0.
Most current “phase through door” reports are network desync or animation timing issues, not active exploits.
Understanding door lifecycle, replication timing, and patch history restores clarity to PvP interactions and prevents false accusations.
Technical understanding replaces frustration.
And informed positioning replaces confusion.
