Halo Studios has laid out the first substantial patch for Halo: Campaign Evolved, and the top item on the list is the one players have been asking for since the remake launched on July 28: you will be able to turn off film grain and chromatic aberration. The update was detailed through the Halo Support account on August 15 with a window of "next week" - so anywhere from August 17 to 21 - across PC, PS5 and Xbox Series X|S.
Both effects are applied heavily in Campaign Evolved, and both have been a running complaint since launch. Film grain softens the sharp, clean look the remake's lighting is otherwise built for, and chromatic aberration smears colour at the edges of the frame in a way that is particularly noticeable on the game's snow and ice environments. Neither had a toggle at launch. Both get one in this patch, which is the single largest visual change the game has had.
Sgt. Johnson stops blocking your campaign
The most consequential gameplay fix is not glamorous. Sgt. Johnson has been getting stuck in the three new prequel missions, where he is scripted to hack doors open before Master Chief can advance. When he failed to do so, the mission simply stopped - a hard progression block with no workaround short of restarting. Halo Studios says that behaviour is addressed.
Two combat fixes round out the list. Jackals will now stagger more reliably when you shoot their exposed hands and feet, restoring a piece of Combat Evolved's original shield-flanking rhythm that had been inconsistent in the remake. And Marines and Flood Marines will fire their assault rifles correctly with the Magnified Skull enabled, a bug that had been quietly breaking one of the game's skull modifiers. Halo Studios has also promised general stability improvements across all three platforms.
Back up your progress first
There is one caveat worth reading twice: installing the update invalidates mid-mission saved progress. Unlocked missions and rally points survive, so you will not lose your campaign, but if you are parked halfway through Assault on the Control Room when the patch drops, you will be restarting that mission from its last rally point. The straightforward advice is to finish whatever mission you are in before you download it.
That is a real inconvenience, and it is the kind of thing that usually signals a change to how save data is structured rather than a simple settings addition - which would be consistent with a patch that is adding rendering toggles and reworking scripted NPC behaviour at the same time.
A quick turnaround for a rocky launch
Campaign Evolved arrived on July 28 as the first Halo game to ship on PlayStation hardware, and its reception has been split. The remake's visual overhaul drew genuine praise; the post-processing choices and a handful of scripting bugs drew most of the criticism. Getting toggles for the two most-complained-about effects out inside three weeks of launch is a faster response than the series has managed in the past.
Halo Studios has not published a full changelog yet, and the five items above are what the studio chose to highlight rather than the complete patch notes. The actual notes should land alongside the update itself sometime this week.
