How to Fix Marathon Stuck on Intro Mission: 2026 Guide to Launch Errors and Loading Screen Freezes
When Marathon finally launched, I jumped in immediately. I’ve always enjoyed shooters from Bungie, and after spending years playing games like Destiny 2, I was curious to see how their new extraction-style experience would feel.
The good news? The gameplay is intense, atmospheric, and incredibly promising.
The bad news? Launch issues hit hard.
Many players, including myself during the first evening, ran into frustrating problems: the tutorial mission freezing, doors refusing to open, or the game getting stuck on the dreaded “Signing In” loading screen.
After experimenting with fixes and reading community discussions, I’ve gathered the most effective solutions that actually work. If you’re stuck at the intro mission or staring at an endless loading screen, these fixes should help you get back into the game.
The Tutorial Door Bug That Stops Progress
One of the weirdest bugs happens during the new player intro mission.
You complete an objective, walk up to the next door… and nothing happens. The door simply stays locked.
Another variation occurs when the “Heal Up” objective never activates, even though you’ve already used the health item.

The unexpected solution: wait
It sounds strange, but sometimes the best fix is simply waiting a bit.
Many players noticed the game is often waiting for a server response before triggering the next event. If that connection lags slightly, the tutorial can appear frozen.
Try this before restarting:
- Wait 60–90 seconds
- Avoid moving or interacting with other objects
- Watch if the objective suddenly updates
In many cases, the mission resumes normally.
Install the latest update
The developers pushed an update that fixes several progression bugs in the intro sequence.
If you’re playing on PC through Steam, make sure your game is updated to the latest version. Consoles usually update automatically when you restart the game.
“Signing In” Screen That Never Ends
Another issue appears even before reaching the tutorial.
You launch the game and suddenly you’re stuck on:
- Signing In
- a screen with animated blocks
- or a loading indicator that never finishes
This usually points to a connection problem rather than a game bug.
Turn off your VPN
One of the most common causes is using a VPN service such as Cloudflare WARP.
VPNs can interrupt the authentication process between the game and Bungie’s servers. When that happens, the login process simply freezes.
If you’re stuck:
- Disable your VPN
- Restart the game
- Log in normally
Some players also report that reconnecting the VPN mid-game can trigger the “Weasel” connection error, so it’s safer to keep it disabled while playing.

Fixing Game File Problems on PC
Sometimes the issue isn’t networking at all. It can simply be corrupted or missing game files.
PC games occasionally install incorrectly, especially right after launch when patches and hotfixes are rolling out quickly.
The easiest fix is verifying the game installation through Steam.
How to verify your game files
- Open your Steam Library
- Right-click on Marathon
- Select Properties
- Open the Installed Files tab
- Click Verify Integrity of Game Files
Steam will automatically scan and repair any damaged files.
Another trick that surprisingly works for some players is moving the game installation to another drive and then moving it back again. This forces Steam to rebuild file paths and occasionally resolves launch freezes.
GPU Driver Issues and AMD Compatibility
Some crashes happen before the game even reaches the menu, particularly on older graphics cards.
Players using GPUs like the RX 580 reported startup freezes or black screens.
In many cases the problem comes from conflicting graphics drivers.
Best solution: clean driver installation
A clean installation removes leftover files from older drivers that might conflict with the game.
The safest approach is using a tool like Display Driver Uninstaller to completely remove your current GPU drivers before installing the newest version from AMD or Nvidia.
This process often solves crashes that happen immediately after launching the game.
Disable Overlays That Cause Launch Problems
Another surprisingly common cause of black screens or freezes is background overlays.
Programs that add overlays to games sometimes conflict with anti-cheat systems or rendering pipelines.
Common overlay-related issues include:
- Discord Clips overlay
- NVIDIA GeForce Experience overlay
- screen recording tools
- third-party performance monitors
If you experience crashes, try launching the game with all overlays disabled. It’s a simple fix that solves more problems than most people expect.
Anti-Cheat Conflicts and BattlEye Errors
Like many competitive shooters, Marathon uses the BattlEye anti-cheat system.
If BattlEye fails to start correctly, the game may stop at the splash screen or display an error message.
Some antivirus programs can block BattlEye components. Players have reported conflicts with security software such as Kaspersky.
Reinstall BattlEye manually
You can reinstall the anti-cheat service with a few simple steps:
- Open the Marathon installation folder
- Locate the BattlEye folder
- Run Uninstall_BattlEye.bat
- Verify the game files through Steam
This forces the launcher to download a fresh installation of the anti-cheat service.
Console Fixes for Xbox and PlayStation
Console players experience fewer driver issues but still encounter loading problems.
The most common cause is the console feature known as Quick Resume.
If the game reconnects using an old session, it may fail to establish a fresh connection with Bungie’s servers.
Recommended fix
- Completely close the game from the console dashboard
- Disable Quick Resume for Marathon
- Launch the game again normally
This forces the game to start a new server connection instead of trying to restore an outdated one.
Quick Troubleshooting Table
| Problem | Recommended Fix |
|---|---|
| Tutorial door won’t open | Wait 60–90 seconds for server sync |
| Infinite signing-in screen | Disable VPN and restart the game |
| Black screen on launch | Verify game files in Steam |
| Startup crashes | Perform a clean GPU driver install |
| BattlEye errors | Reinstall the anti-cheat service |
| Console loading freeze | Disable Quick Resume and relaunch |
Final Thoughts from a Marathon Fan
Even with the rough launch, Marathon already shows a lot of potential.
The tense exploration, stylish environments, and Bungie’s signature gunplay create moments that feel genuinely exciting. Once everything works properly, the gameplay loop becomes incredibly addictive.
Unfortunately, many modern online games experience technical hiccups during their first weeks. Servers get overloaded, patches roll out quickly, and unexpected bugs appear.
The good news is that most of these problems are easy to fix, and the developers are actively pushing updates.
If you’re stuck on the intro mission or staring at a frozen loading screen, don’t panic. Try the solutions above, give the game a fresh start, and you’ll likely be back exploring the world of Marathon much sooner than you expect.
