Knowing the geometry by heart
There are a handful of games I can still see from the inside, and the first Halo is one of them. Not the plot. The geometry. The beach on The Silent Cartographer, the moment the Hunters commit and you have to decide whether to back off or slide behind them, the grenade arc you learn without ever being taught it. Combat Evolved built that muscle memory into an entire generation of players, and any remake of it walks into a room where everybody already knows the furniture.
So the question I brought to Campaign Evolved was narrow and slightly unfair. Does it feel like Halo when you are not looking at it? Not whether the ring is prettier, because of course it is prettier, but whether the grenades bounce the way your hands expect and whether Master Chief still has that specific low-gravity float when he jumps.
He does. That is the headline, and it is a bigger achievement than the art. Halo Studios kept chunks of Bungie’s original Blam code underneath the Unreal Engine 5 presentation layer, specifically to preserve the physics and the enemy behavior, and you can feel the decision within about ninety seconds of taking control. Everything else in this review is downstream of the fact that they got that right.
What Campaign Evolved actually is
This is a full rebuild, not the 2011 Anniversary treatment where you pressed a button and swapped the textures. Geometry, lighting, cinematics, dialogue and score have all been remade. Halo Studios, which is the studio formerly known as 343 Industries, moved off the in-house Slipspace engine after Infinite and built this on Unreal Engine 5 with Lumen handling global illumination, Nanite handling geometry and MegaLights doing the interior and local lighting work.
You get 13 missions. Ten of them are the original campaign, rebuilt and in places reshaped. The other three are new, set a year before the crash of the Pillar of Autumn, grouped as Operation: METEORITE and starring Master Chief alongside Sergeant Avery Johnson. The weapon sandbox grows by nine guns pulled forward from later games, including the Energy Sword, the Battle Rifle, the SMG, the Sentinel Beam, the Fuel Rod Cannon, the Spiker, the Beam Rifle, the Brute Plasma Rifle and Reach’s Needle Rifle. Brutes now show up in a campaign that never had them, and the Flood arrive with the pure forms Halo 3 introduced.
What you do not get is competitive multiplayer. None of it. The subtitle is doing honest work.
Four changes that matter, and one that does not
Sprint is here, on by default, and you can switch it off in the settings. I left it on for the first run and off for the second, and the version with sprint disabled is the better game. Not because sprint is heresy, but because Combat Evolved’s encounter design assumes you cannot leave. Flood ambushes in tight corridors are built around the panic of being cornered, and a sprint button turns the panic into a jog toward the next door. Vehicles lose weight too, because walking stops being slow enough to make a Warthog feel like a rescue.
Hijacking is the second change and I like it more than I expected. Pulling a Grunt out of a Ghost was a Halo 2 idea, and letting it loose in a campaign where Wraiths are drivable produces some of the funniest chaos in the game. The Warthog gets a fourth seat on the rear bumper, which is a small thing until you are running four players and nobody has to sit out.
The third is the Warthog itself, which now handles like something with a functioning suspension. That sounds like an improvement and it is a loss. The old Warthog’s stupidity, the way it would bite a rock and pitch you into a canyon, was the source of the tension in the final escape. Make it obedient and the escape becomes a driving section.
The fourth is wayfinding. There are markers now, telling you exactly where to walk, in levels whose architecture was already telling you exactly where to walk. You can hide them in the HUD settings, but the level design has also been sanded in places to accommodate them, and that you cannot switch off. The Library is the interesting test case. It has been shortened and the encounters varied, and it is genuinely less of a slog than the 2001 version. It is still the weakest mission in the game. Some problems are structural.
The change that does not matter, for the record, is the expanded arsenal. I was ready to hate finding an Energy Sword in a 2001 campaign. In practice the new guns are placed with restraint, they never displace the pistol or the assault rifle from their central role, and the game is more varied for them.
Operation: METEORITE
The three new missions are the clearest evidence of where this studio’s instincts sit, and they are the part of the package I would cut first. Chief and Johnson board a Covenant ship, and you spend most of the running time in purple corridors with a mid-section that steps outside for air. The encounters lean on doors as spawn points, which means fights announce their seams, and several of them run past the point where they are still enjoyable.
There is real quality in there. One early area is essentially an indoor skate park designed for Ghosts, and it is the most inventive single space in the game. The later weapons get to cut loose here in a way the main campaign sensibly refuses to allow. The concluding set piece has scale.
The problem is tone. Chief and Johnson banter like characters from a different, chattier Halo, and the difficulty tuning on Heroic is out of step with the ten missions beside it. Brutes soak far more ammunition than the arenas provide, and the honest fix is to drop a notch for these three and come back up afterward. Roughly ninety minutes to two hours of content, and the weakest ninety minutes in the box.
The story, and the voices
The plot is untouched, which is right. A crashed warship, a ringworld nobody understands, an AI who knows more than she is saying, and the slow horror of realizing what Halo is actually for. It is still one of the cleanest science fiction structures in the medium, and the remade cinematics give it the staging it never had, with blocking and sequencing rebuilt from Bungie’s original storyboards and production assets.
Steve Downes, Jen Taylor and Tim Dadabo are all back as Chief, Cortana and 343 Guilty Spark. Keston John takes over Sergeant Johnson from David Scully, who retired in 2013, and he is good, though he plays the character warmer and looser than the original read. Cortana is the one who gains most from the rerecording. Taylor’s performance has twenty-five years of knowing this character behind it, and the moment the ring’s purpose lands hits harder than it used to.
How it looks and runs on Xbox Series X
Two graphics modes, as the developers document them: Quality targeting 30fps at higher resolution, Performance targeting 60fps. Both use dynamic resolution scaling, and the Xbox versions reconstruct the image with Temporal Super Resolution. Performance mode is the one to use. It holds its 60 through firefights, the resolution scaler does its work quietly enough that I never caught it dropping, and 60fps matters more in a shooter with this much airborne plasma than any amount of extra pixels.
Where the Series X version slips is cinematics. Both modes drop frames during the cutscenes, and it is the one place where the console you own visibly decides your experience, because the PlayStation versions do not have the problem. There is a related known issue that is worse: suspend the game during a cinematic and the last frame stays burned onto every cutscene for the rest of the playthrough, and the only fix is a full console restart. If your television is running at a refresh rate that is not a multiple of 30 Hz, or you have Variable Refresh Rate on, the stutter gets worse. Set the panel to 60 or 120 Hz, turn Game Mode on, and it mostly goes away.
As for the art itself, this is a beautiful game with a specific cost. Unreal Engine 5 pushes everything toward the photoreal, and Alpha Halo used to look like nowhere on Earth. The mist and the flat, strange color palettes of 2001 made a ring built by dead aliens feel genuinely inhuman. Campaign Evolved’s version is a gorgeous mountain range with a river in it. The Forerunner interiors take the same trade, swapping brutalist concrete for reflective steel that throws so much light around during a firefight that readability suffers. I lost more shots to visual noise here than I ever did in the original, and readability was the thing Bungie prized above everything.
The score, and what happened to the guns
Martin O’Donnell and Michael Salvatori’s music has been remastered rather than reinterpreted, which is the correct call, and it still does more heavy lifting than anything else in the presentation. The monks come in over the opening and the whole thing snaps into place. The bonus missions borrow arrangements from later games in the series, which is a nice touch that also quietly admits those missions needed help.
The weapon audio is where I would file a complaint. The assault rifle’s scream has been pushed down in the mix and it has lost its authority. The Beam Rifle traded its shutter click for a generic laser noise. Worst, plasma grenades have lost most of their visual gas and their hiss is buried, which turns a stick from a warning into a surprise. That is a design regression dressed as a sound design choice, and I died to it more often than to any enemy in the game.
Skulls, Remix and how the time actually goes
The main campaign runs eight to twelve hours depending on difficulty and how much you poke at the walls, with Operation: METEORITE adding another hour and a half or two. Full completion is fifteen to twenty.
The replay structure is the most generous thing in the package. There are 42 Skulls, 26 of them returning from previous Halo games and 16 new, with 39 hidden three per mission and the last three handed over when Campaign Remix opens up. The new ones range from silly to genuinely transformative: Perspective flips the whole campaign into third person, The Floor is Lava damages you every time you touch the ground. Campaign Remix randomizes enemy placement, weapon placement and enemy behavior, and its Armistice modifier makes every faction fight you together instead of each other, which reorganizes encounters you thought you had memorized. This is the part of Campaign Evolved that justifies keeping 70 GB installed after the credits.
Co-op is four players online with crossplay and cross-progression, or two locally in split screen on console, and split screen surviving into 2026 deserves saying out loud. Twelve accessibility features are listed on the store page and eleven languages are supported. PEGI 16 for violence and horror.
The state of the build
I finished the campaign on build 2026.07.25.1112544, the July 29 patch, which is a 13 GB download on Xbox and resets any mid-mission save you were sitting on when it installs. It is a good patch. Jackals in the hangar hallway on The Truth and Reconciliation now patrol instead of standing around, the Spec Ops Elites near Rally Point Delta on Assault on the Control Room actually engage, the Hunter pair at the cartographer’s entrance stops ignoring you, and a charged Plasma Pistol shot no longer kills a player who has full health and shields, which was a real problem.
Things that are still broken: a progression blocker on Two Betrayals if you destroy the Banshee after the first generator, audio popping in The Truth and Reconciliation, cinematic audio drifting out of sync if you pause mid-scene, and navigation markers in co-op that refuse to advance until the whole Fireteam has walked past them. None of these ended a playthrough for me. All of them are the kind of thing a game with this budget should have caught.
Verdict
Campaign Evolved is a very good remake of a great game, made by a studio that understood exactly which parts were load-bearing and then made four or five changes it did not need to make. The physics are right, the AI is right, the sandbox additions are handled with restraint, the music still lands, and playing through Halo again at 60fps with this much detail on the ring is a real pleasure. Against that, the art direction trades strangeness for prettiness, the sound design has quietly downgraded two of the most important audio cues in the series, the bonus missions are filler, and the absence of any competitive multiplayer leaves the package feeling smaller than 59,99 euros suggests.
Buy it if you have Game Pass Ultimate, in which case stop reading and go install it, or if you have never played Combat Evolved and want the version that will not feel like homework. Buy it at full price if playing the ring in Unreal Engine 5 with three friends is worth 60 euros to you on its own, because that experience is genuinely excellent. Skip it if you already own the Master Chief Collection and mainly want more Halo per euro, because you already have more Halo per euro, and turn the sprint off either way.
