Call of Duty: Modern Warfare 4 Early Access Beta Live on PS5 — Maps, Modes, and Campaign Mission Detailed

The Call of Duty: Modern Warfare 4 Early Access Beta has gone live on PlayStation 5, giving pre-order holders and Beta code recipients their first chance to experience the franchise's return to grounded, boots-on-the-ground combat. This year's beta cycle marks a significant departure from recent entries by introducing a playable Campaign mission for the first time in Call of Duty beta history, alongside a solid multiplayer suite spanning six core maps, new game modes, and the modular Kill Block arena. For players who have been waiting to see how the series evolves after the movement-heavy iterations of the past few years, this beta represents the most comprehensive pre-launch test in recent memory.

The beta arrives in two distinct phases. Weekend One runs through August 25 at 10:00am PT and requires either a pre-order or a redeemed Beta code for access. Weekend Two opens the floodgates as an Open Beta from August 28 at 10:00am PT through September 1 at 10:00am PT, requiring no purchase or code whatsoever — just a PlayStation 5 and a download from the PlayStation Store. Critically, all progression, weapon open ups, and operator progress from Weekend One carries directly into Weekend Two, meaning early adopters won't lose a step when the broader player base arrives. Eight rewards await players who reach Level 30 across both weekends, including the Dread Tiger Operator Skin for Reece and a Beta Forged Weapon Blueprint for the Han 86 Assault Rifle, all of which transfer to the full game at launch on October 23.

Franchise Fatigue or Fresh Renaissance?

Modern Warfare 4 keeps the focus on gritty, foot‑to‑metal firefights while adding sensible ways to move. You can climb and rapidly descend pipes, reposition while hanging from ledges, and aim and fire while suspended. The design rewards a player who drops from a pipe, leans a ledge, and slides straight into cover. Chaining those moves lets you keep your speed and keeps maps sharp.

To help players internalize these mechanics, the beta includes a dedicated Mobility Course training facility. Guided tutorials walk through fundamentals like pipe climbing, ledge hanging, and suspended firing, while timed courses challenge players to string movements together efficiently. The course tracks completion times and weapon handling metrics, giving competitive players a concrete benchmark to chase across both beta weekends.

Modern Warfare 4’s Beta: Gunsmith 2.0 — and Apex Attachments

The beta puts 22 weapons in players' hands, accessible through multiplayer progression, default loadouts, and the Campaign mission. Gunsmith returns with its full customization suite, but the headline addition is Apex Attachments — specialized modifications that alter how a weapon performs without taking up a standard attachment slot. For players who treat loadout theorycrafting as a mini-game unto itself, Apex Attachments add a new layer of optimization to chase.

Complementing this depth is Gunny, an in-game recommendation system that suggests weapon builds based on the attachments a player has already open uped. Rather than parsing spreadsheets or community guides, newer players can let Gunny surface viable configurations tailored to their current arsenal. It's a smart onboarding tool that respects the complexity of Gunsmith without demanding a PhD in ballistics to participate. Between Apex Attachments and Gunny, the beta signals a clear design philosophy: deep customization for enthusiasts, accessible entry points for everyone else.

MW4 Beta First Impressions

Six core 6v6 maps anchor the beta's multiplayer offering: Rooftops, Silkworm, Transit 213, Cachette, Lotus, and Lithium. These span snow-covered New York rooftops, a dense South Korean shopping district, a covert armory near a French rail terminal, and a Mexican lithium refinery — a geographically diverse roster that should test the new movement system across varied verticality and sightline profiles. Classic modes Team Deathmatch, Domination, Hardpoint, Kill Confirmed, and Search and Destroy return alongside two new additions. Inflation converts eliminations into cash bounties; dying drops a portion of your bank, creating high-stakes risk/reward loops. Hijack centers on a Data Spike that players carry, throw, and pass between teammates en route to the enemy Comm Station, planting it to score over time and defending it through detonation for a bonus.

Then there's Kill Block, the Westbridge Training Facility's modular live-fire battleground. Built from three interconnected Slabs, Kill Block reconfigures its routes, sightlines, weather, and combat spaces between rounds across more than 500 possible combinations. It hosts classic 3v3 Gunfight and a new 10v10 Gunfight variant that scales the intimate duel format into something closer to a chaotic skirmish. For larger-scale warfare, Ground War: Combat Outpost delivers 24v24 vehicle and infantry combat across two maps — Imjin Farmland and Wolves Stadium — where teams establish Outposts to earn resources, complete objectives, and contend with airborne Killstreaks. The variety here is staggering: from three-life elimination rounds to persistent 48-player battles, the beta covers nearly every engagement scale the franchise supports.

Campaign Mission 'Entrenched' Makes Beta History

For the first time in Call of Duty beta history, a Campaign mission is playable before launch. 'Entrenched' drops players into a large-scale assault alongside infantry and armored vehicles, tasked with preventing a strategically vital nuclear power station from falling into enemy hands. The mission showcases the game's large-setpiece ambitions — combined arms gameplay, destructible environments, and AI companions that participate meaningfully in the push. Including Campaign content in a multiplayer-focused beta is an unusual move that serves dual purposes: it gives solo players a reason to participate even if competitive modes aren't their primary draw, and it stress-tests the engine's ability to handle large-scale scripted encounters alongside the multiplayer infrastructure. Early impressions suggest the mission plays more like a proof-of-concept for the Campaign's scope than a representative slice of the full story, but its inclusion alone is noteworthy.

Warzone’s Zodiac Takeover Begins Friday

When Weekend Two launches on August 28, Call of Duty: Warzone joins the beta with a Resurgence experience on Zodiac, an all-new map set around a DRC Advanced Systems drone assembly and manufacturing headquarters. The map spans offices, rooftops, tunnels, and surrounding shoreline, offering the vertical variety and close-quarters density that Resurgence thrives on. Standard Resurgence mechanics apply: eliminating enemies and completing Contracts shortens squad redeployment timers, keeping eliminated teammates in the fight and accelerating the pace toward a final circle showdown. Zodiac's industrial aesthetic — manufacturing floors, loading bays, server rooms — suggests a map designed for tight interior fights punctuated by rooftop sniping and tunnel flanks, a layout that should complement the new movement system's vertical traversal tools.

The decision to fold Warzone into the Modern Warfare 4 beta rather than treating it as a separate test underscores the integration between this year's premium release and the free-to-play battle royale. Progression, open ups, and movement mechanics carry across both experiences, meaning time spent in Multiplayer directly benefits Warzone performance and vice versa. For players who split their time between the two modes, this unified progression is a quality-of-life improvement that eliminates the double-grind of previous years. The beta's structure — Multiplayer and Campaign first, Warzone second — also creates a natural onboarding ramp: learn the movement and gunplay in controlled 6v6 matches, then apply those skills in the larger, less forgiving Resurgence arena.

Call of Duty: Modern Warfare 4 launches October 23 on PlayStation 5. The beta's breadth — spanning movement tutorials, a modular arena with hundreds of configurations, a playable Campaign mission, and a Warzone map debut — suggests a launch package built to sustain multiple player communities simultaneously. Whether that ambition translates to a cohesive live-service ecosystem remains to be seen, but for now, the PS5 download is free for Weekend Two participants, and the Han 86 blueprint is waiting at Level 30.
