Halo: Campaign Evolved Patch Details & Series Future

If you've been playing Halo: Campaign Evolved this week, you probably noticed the very first official update since the game launched. And honestly, there's a lot to unpack. The patch varies wildly depending on where you're playing. On XBOX, you're looking at roughly 13 GB, PlayStation comes in around 7 GB, the Microsoft Store version is about 4 GB, and Steam users are downloading a hefty 21 GB.

If you own the game on both Steam and the Microsoft Store, though, be warned: some players, including people testing it firsthand, ended up having to redownload the entire 69 GB game just to get the Microsoft Store version updated. It's unclear if that's intentional, but you're not alone if it happened to you.

This update brings better stability across every platform, tweaks to how enemies behave in combat, and a handful of other fixes.

One thing to keep in mind: installing it will wipe any mid-mission save progress you had going. Your unlocked missions and rally points, though, will stick around. As for what's actually inside the update, PC players on NVIDIA or AMD cards with outdated or known-problematic drivers will now get a warning pop-up when booting up the game, which should help cut down on a lot of the crashes and glitches people have been running into.

There's also general stability work done on the Pillar of Autumn mission, though if you've struggled through the Warthog Run specifically, you'll want more of that; the frame drops there have been rough enough that dropping your settings to medium was basically required just to get through it smoothly.

The most talked-about fix, though, is one that's been driving Legendary players up the wall: a charged plasma pistol shot can no longer instantly kill you even at full health and shields, on any difficulty. That one-shot bug was a nightmare for anyone actually trying to earn achievements legitimately, especially with how many people have reportedly been cheesing them instead.

There are a bunch of smaller AI fixes too, mostly things the average player probably won't even clock, like enemies no longer wandering into spots they shouldn't be in. Even with this update out, there's still a solid list of things Halo: Campaign Evolved needs to address, based on player feedback and firsthand experience with the game. Active Camouflage is still inconsistent and needs real attention.

The customization system is another sore spot.

There's a new skin currently locked behind a student verification program, which feels like an unnecessarily complicated way to gate content when there aren't even proper earnable cosmetics for regular players to work toward. Ideally, some of these unreleased skins that have already leaked should be tied to in-game achievements instead.

There's also no campaign scoring, timing system, or leaderboard of any kind, which feels like a big miss for a campaign-focused release, especially for anyone who enjoys speedrunning. The Warthog could use some love too; right now, swapping seats is instant with zero animation, when even Halo Infinite managed to include a proper transition for that.

Checkpoints are probably the biggest complaint. It's entirely possible to go 10-15 minutes without one triggering, only to reload the same section and suddenly get a checkpoint mid-firefight instead. Thankfully, the double revert option exists, because without it, a proper softlock during a LASO run is a real possibility. Then there's the Magnified Skull; turning it on currently breaks the Marines' ability to fire their weapons entirely.

Modders have already patched this on their end, so hopefully an official fix isn't far behind. On the performance side, sales numbers are murkier than they used to be for games in general, but what can be confirmed is that Halo: Campaign Evolved was the top-selling title across PlayStation, XBOX, and Steam at launch.

That's a strong start, though it's unlikely to hold given this is a remake of a game many players have already finished multiple times.

Not every reaction has been fair, though. A viral post claiming that certain female crew members on the Pillar of Autumn bridge can't be killed racked up millions of views and thousands of likes — and it's simply not true. Load up that mission yourself, and you'll find the entire command crew is fully killable, no exceptions.

Watching real criticism get drowned out by made-up stuff is frustrating, especially since the point of flagging real issues with Halo: Campaign Evolved is to push for improvements. On a brighter note, modders have been going wild this week, visual overhauls ditching the film grain, audio mods bringing back classic weapon sounds, and fixes restoring Cortana's original dialogue.

Every faction, including the Elites, is now playable through mods. There's also a fan-made day-night cycle now in the game, and rumblings that multiplayer might eventually be possible too, with some modders reportedly working on porting entire maps over.

Menu tweaks are being tested too; the community's clearly putting in real work here, worth keeping an eye on. On the multiplayer front, there's actual official movement: a small internal team at Halo Studios has reportedly gotten approval to prototype a PvP mode using that same hybrid engine; Unreal Engine for visuals, the original Halo engine handling physics and core systems underneath.

As for the next mainline entry in the series, that appears to still be a ways off.

But there's now solid confirmation that both a Halo 2 remake and a Halo 3 remake are in the works, thanks to the Legendary ending featuring Sergeant Johnson being included in the game's files. What's surprising is that Halo Studios published the full set of cutscenes, secret ending included, right as the game entered early access — before the wider public even got a chance to play it.

That's an unusual move for a major studio, and it meant the reveal didn't get to organically spread through the community the way these things usually do, which feels like a missed opportunity. A Halo 2 remake almost certainly means playable Elites will return in some form, given the Arbiter's role in that story.

There's also hope that unused content and cut storyboards from both Halo 2 and Halo 3 get another look, since so much material never made it into the final games. That said, there's some hesitation here too, since Halo: Campaign Evolved itself added very little truly new content to the original game.

One nice example that did make it in is the restored section on the level Two Betrayals, where a previously cut third pulse generator area now houses the Mythic Skull, a small but meaningful addition that shows what's possible when Halo Studios goes back and restores cut content properly. Then there's the ODST situation.

Rumors suggest Halo Studios and Microsoft have been quietly discussing some kind of ODST follow-up or spin-off internally, informally referred to as ODST 2.

There was even speculation floating around that Activision could somehow be attached to the project, though that remains unconfirmed. What's fueling the rumors further is that Pierre Hintze, the head of Halo Studios, recently changed his LinkedIn cover photo to an ODST banner pulled from The Master Chief Collection. That's not confirmation on its own, but it's a pretty strong hint, whether intentional or not.

Whether this ends up being a story-driven spin-off or something more like a multiplayer-focused, Call of Duty-style ODST experience is still unknown. Finally, on the development side of things, multiple sources close to the project have independently pointed to the same issues behind the scenes.

One outside studio's contribution was reportedly so poor in quality that it set the project back roughly six months, forcing parts of it to be rebuilt from scratch. Combine that with Microsoft's continued reliance on outside contractors and the natural growing pains of shifting long-time staff over to Unreal Engine 5, and it paints a picture of a genuinely difficult development cycle.
