Microsoft has released Halo: The Master Chief Collection for PC, kickstarting the migration of the hit Xbox shooter to Steam and Windows 10. The six-piece compilation sees a staged, per-game rollout commencing with Halo: Reach, reviving Bungie's final farewell to the franchise beyond Xbox 360. That comes with significant graphics enhancements to push for 4K, alongside overcoming the challenges of the PC ecosystem bypassed by Xbox consoles.

While Halo: Reach hits PC as an impressive return to the 2010 classic, players are facing a range of graphical, audio, and gameplay bugs and issues. We've rounded up the most prominent Halo: Reach PC hiccups surfacing on launch day, alongside potential workarounds.

With Halo: Reach PC rolling out worldwide, we'll update this list with new bugs and fixes as they surface. Found a bug? Let us know in the comments.

Halo: Reach audio and sound issues

Among the most widespread problems impacting the Halo: Reach re-release is a nasty audio bug, diverging from the soundscape of the original 2010 title. It means some sounds may be muffled, muted, or incorrectly mixed. Microsoft warned of potential hiccups ahead of launch, related to changes to the game's audio encoding, with work underway on a fix. "We are aware that areas of the title don't sound like what you or we ideally want them to," stated Community Support & Engagement Coordinator at 343 Industries, Tyler Davis.

"It will take some time to work through solutions to improve the overall experience for audio and that work is already underway. When it is ready, we will flight to test the fixes we can make prior to updating the title. We also plan to go into more detail on our Reach audio journey in a later blog."

Halo: Reach PC stuttering and lag

Some Halo: Reach PC users report stuttering and lag spikes across all modes. Microsoft has acknowledged issues with certain setups, however, causes and solutions will vary between systems.

Workaround: The newly-added unlocked framerate causes many stability issues for PC, likely to be addressed in future updates. However, Microsoft has warned that Corsair iCue, Logitech G-Hub, and Razer Synapse may cause stuttering with Halo: Reach PC. Disable these programs if installed, when experiencing stuttering and input lag.

Halo: Reach PC freezing and crashing

Halo: Reach may freeze or crash, as a possibility with any PC release. Many report encountering issues during start-up, with a fix likely required to avoid any possible conflicts. Microsoft also confirms a "known crash" when exiting the game.

Halo: Reach PC screen tearing

Halo: Reach PC may exhibit screen tearing, regardless of V-Sync, and other anti-tearing measures. The result of new frames pushed to your display mid-refresh, two separate images may display on two halves of the screen. Many users report heavy screen tearing across a variety of PC setups. "The team is aware of issues around screen tearing and V-Sync not performing as expected for some users," Microsoft stated. "As a reminder, if V-Sync is off, screen tearing will happen." Microsoft continues to investigate issues post-launch.

Delayed mouse input

Microsoft details a number of reports of mouse input exhibiting latency, causing delayed in-game controls. Microsoft is attempting to isolate the issue to specific setups, recommending users contact Halo Support.

'UE4 Critical Error,' 'You've been banned' errors

Halo: The Master Chief Collection PC may output EAC error messages, including a "UE4 Critical Error," "You've been banned," and more. Microsoft has acknowledged an issue, encouraging affected users to contact Halo Support. While UE4 errors appear present, Microsoft claims to have addressed erroneous ban messages.

Workaround: Microsoft recommends players use the latest version of Windows available, eliminating a share of hiccups on PC. If persisting, Steam's "Verify Files" feature may resolve issues tied to local files, while Microsoft Store users should complete a full reinstall.

Unable to crouch while moving

Halo: Reach PC restricts players from crouching while moving their character. To crouch, players must stand still, before pressing the assigned crouch key. Microsoft states this is a legacy issue stemming from the Xbox 360 release when moving and crouching simultaneously were unnatural via the gamepad. The team is "currently testing and prototyping potential alternative solutions to address the community's feedback," expected with future updates.

The Halo: The Master Chief Collection menu may demonstrate poor performance across some setups. "We are investigating on our end but need more data points of this issue," said a Microsoft representative. "If you are experiencing this problem, please visit the Halo Support site and create a ticket."

Other miscellaneous issues

  • When using Bluetooth-connected headphones with Halo: Reach PC, users may lose audio after opening the game's main menu. Microsoft has acknowledged the issue, attributed to how the title prioritizes devices, with a simple step-by-step fix available.
  • When a capture care is designated as the default audio input device, PC audio will transmit over the voice channel.

Tip of the Spear performance drops

Microsoft has acknowledged some players may experience cutscene performance issues throughout Tip of the Spear when using AMD hardware. While no formal fix has been provided, expect a fix moving forward.

ONI: Sword Base not loading

The game's second playable mission ONI: Sword Base won't load for some players. Microsoft is yet to acknowledge the issue, although appears to be affecting a handful of unlucky PC users.

Latency during Campaign co-op

Cooperative multiplayer Campaign sessions may cause drastic input lag for all connected players, besides the session host. Microsoft has acknowledged the issue facing some players, although it was unable to promise a significant fix. "Co-op campaign play uses P2P networking and we're aware that some players are reporting high latency and a poor experience when playing Campaign together," a Microsoft representative states. "This is an area the team will continue to monitor but given the complexities of P2P networking and the underlying net code of Reach, the extent to which this issue can be addressed is still TBD."

Miscellaneous Campaign issues

  • Character models may temporarily desync after performing an assassination.
  • When playing cooperative multiplayer modes, entering an elevator may activate an unintended falling animation.

Slow multiplayer matchmaking (Fix deployed)

While Halo: Reach PC multiplayer connectivity has proven relatively stable from launch, many report issues with slow online multiplayer matchmaking, paired with the "Connecting Session" message, attributed to the relays feature. Microsoft has deployed a fix for relays blocking matchmaking, pledging to continually "monitor relay performance and matchmaking" in the near term.

Workaround: Microsoft claims to have fixed relays impacting matchmaking for Halo: Reach PC. Otherwise, it advises players to turn off relays via the Halo: Reach "Network Settings" menu, to disable the feature.

Steam friends don't display in-game

Workaround: Join friends through Steam's integrated friends list.

Halo: Reach Steam Achievements fail to unlock

Halo: Reach PC players report some Steam Achievements failing to unlock, even after completing required milestones in-game.

Existing Xbox achievements missing from Steam

Halo: The Master Chief Collection hits PC with cross-platform achievements, allowing existing Xbox unlocks to translate to Steam Achievements upon linking your Xbox Live account. Some users report that existing Xbox Achievements may fail to transfer between platforms accurately.

Uninstalling Halo: Reach Steam breaks Microsoft Store install

If Halo: Reach PC is installed on the Microsoft Store alongside the Steam version, uninstalling the Steam version will remove the Easy Anti-Cheat client, and rendering the Microsoft Store game unplayable.

Workaround: Microsoft recommends players uninstall and reinstall Halo: Reach via the Microsoft Store if encountering this issue.

Missing Language Packs

When launching Halo: Reach PC is launched via Steam in Portuguese, Chinese, Japanese, or Korean, required Language Packs may not automatically install. Microsoft has acknowledged the issue, providing a simple step-by-step fix.

Halo: Reach PC fails to launch via Microsoft Store and Xbox App

Halo: Reach PC may fail to launch when installed via the Microsoft Store. This can be attributed to a variety of potential causes, both after purchasing the game or using Xbox Game Pass. Some report Halo: Reach launching only when opened via the Start menu, rather than the Microsoft Store, and Xbox apps. Microsoft has acknowledged the issue, working with the Xbox Game Pass team, stating a "hotfix is expected soon."

  • Also no stats saved or achievements. Its another known issue on forums over at halowaypoint
  • I've been getting achievements on PC, quite surprised they're actually syncing to my MCC achievements from the Xbox One
  • I haven't unlock any achievements. :S and stats are not recording even when im log on xbox live. I even look on forums no stats on my profile just all blank.
  • This isn't an issue for me either. I was suprised that everything carried over. I don't know if save files will for inside mission checkpoints.
  • For me the worst thing is no tutorial
  • Why would you need a tutorial for a fps game like Halo? If it's just needing to know your key bindings just open up settings and go to controls...
  • I ran out of ammo way about 2/3rd's through the mission. I only had 2 guns but had the option to switch to an alien gun if I stood over a kill. How do health and shields work and get replenished? I know I can hide and hold shift for awhile and the shields to replenish but must be more to it. I gave up when the rest of Noble Team was waiting for me to use a target locator. I have how to get it or use it.
  • If it moves, shoot it.
  • The performance of the game is fine, however I just finished playing online co-op with a friend. The matchmaking or whatever you want to call it is horrendous, it would load us into separate maps every time we loaded a new level. I hope this is fixed soon, it's very annoying and a huge waste of time having to restart the game so many times.
  • Welcome to MCC, it's arse.
  • Not quite, my teammates complain when I shoot them and those ostriches will not die.
  • Why this message ended up here I have no idea
  • MCC/Reach doesn't work for me. I get in main menu and it freezes and i have to cntrl-alt-delete & terminate it. I was on an insider build, re-installed retail and same problem.. but hey, at least fusion 360 works again on retail. Hopefully MS fixes it soon. Ryzen+RX480+ GamePass = crash on main menu, no play right now :(
