Update 16.754.404 Overview
Halo Studios shipped the first post-launch patch for Halo: Campaign Evolved on July 29, 2026. Console players see it as update 16.754.404; PC builds report version 2026.07.25.1112544. Download size is roughly 7 GB on PlayStation 5 and varies by platform.
This is a stability and quality pass—not a content drop. Expect hotfixes for crash paths, enemy AI regressions, and PC driver edge cases rather than new missions or armor waves. Halo Waypoint and Halo Support publish the authoritative notes; this wiki summarizes verified fixes for fireteam planning.
Important: installing the update can reset mid-mission saved progress. Unlocked missions and Rally Points stay available—you only lose in-mission checkpoints created before the patch landed.
- Version — 16.754.404 (build 2026.07.25.1112544)
- Released — July 29, 2026 (worldwide)
- Scope — stability, AI, PC driver warnings, account linking
- Save note — mid-mission saves reset; missions and Rally Points persist
Stability & Performance
The Maw received targeted stability work when skipping or watching the opening cinematic while FSR is enabled on AMD graphics cards running driver versions 26.6.2 or 26.6.4. If you still crash, switch to DLSS, XeSS, or TSR—or roll back to AMD driver 26.6.1.
Pillar of Autumn saw general mission stability improvements across platforms. Players with large friends lists on Windows PC, Steam, and PlayStation 5 should notice reduced menu hitching after this patch.
All PC versions now show a warning at launch when an AMD or NVIDIA GPU driver version is known to cause crashes. Update or roll back before a Legendary push if the prompt appears.
Campaign AI Fixes
Several launch-week AI bugs were corrected in this build. These were mission-blocking or immersion-breaking enough that Halo Support tracked them from day-one tickets.
| Mission / Area | Fix |
|---|---|
| The Truth and Reconciliation — hangar hallway | Jackals now patrol correctly instead of standing idle |
| Assault on the Control Room — Rally Point Delta | Spec Ops Elites now attack the player as intended |
| Assault on the Control Room — exterior | Enemies no longer wander into the Control Room exterior |
| The Silent Cartographer — cartographer entrance | Hunter pair now consistently engages the player |
| Global — Plasma Pistol charged shot | Charged shots no longer instantly kill full health and shields on any difficulty |
Account Linking
PlayStation and Steam players linking Xbox accounts now see Xbox Gamertags throughout the account-linking flow. That makes it easier to confirm you are redeeming armor codes and co-op invites on the correct Microsoft profile.
If a Waypoint redemption still lands on the wrong account, sign out everywhere, link through Steam app 2806050 or your console store, then retry Drops & Code Redemption once entitlements sync.
Still Open After This Patch
Update 16.754.404 does not fix every launch issue. Two Betrayals Banshee softlock, cinematic stutter on non-30 Hz multiples, co-op navigation markers waiting for the whole fireteam, and several PC-specific driver paths remain tracked on Halo Support.
For workarounds, driver versions, and platform quirks, see our Known Issues page at /known-issues/. We update that hub whenever Waypoint posts a new hotfix list.
- Two Betrayals — Banshee softlock still open (critical)
- Cinematics — stutter on odd refresh rates; pause/resume desync
- Co-op — objective markers wait for all four Spartans
- PC — Steam .exe launch, custom bindings reset, RTX 50 driver crashes
- XeSS — Frame Generation + frame cap can freeze visuals (use FSR/DLSS FG instead)
