Call of Duty: Modern Warfare 4 Is Out Now: Movement, Visual Tech and Switch 2 Support Explained

Call of Duty: Modern Warfare 4 is officially live. Infinity Ward and Activision released the game today, October 23, 2026, on PlayStation 5, Xbox Series X|S, PC and, for the first time in over a decade, a Nintendo handheld. Most of the pre-launch coverage has focused on maps, modes and weapons, but the bigger story on day one is how different the game feels and looks to actually play. Here is what's new under the hood: the movement system, the visual technology, the PC-specific work, and the surprise Switch 2 release.

1. Modern Warfare 4 Has Officially Launched

Modern Warfare 4 is available now on PlayStation 5, Xbox Series X|S and PC via Battle.net, Steam and Xbox on PC. It is not coming to PlayStation 4 or Xbox One; Infinity Ward and Activision confirmed last-gen consoles are sitting this release out. The Campaign follows Private Park, a young South Korean soldier thrown into a full-scale North Korean invasion, while Captain Price runs a parallel, off-book operation that eventually collides with the forces behind the war. Multiplayer and DMZ round out the package at launch, with Season 1 for both Modern Warfare 4 and Call of Duty: Warzone arriving shortly after.

If you want the breakdown of which edition to buy or what carries over into Warzone, our edition-by-edition launch guide covers pricing and pre-order perks in detail. This piece focuses on what Activision has said about how the game actually runs and moves.

2. A Full Movement Overhaul: Mantle, Climb, Hang and Jump

Infinity Ward rebuilt how Operators move through the world for this release. According to the official announcement, movement in Modern Warfare 4 is "built around fluidity, control, and player freedom," with traversal, combat movement and gunplay transitions designed to preserve momentum without sacrificing control under pressure.

The headline additions are expanded options for Mantling, Climbing, Hanging and Jumping. Together they're meant to open up vertical spaces that older Modern Warfare entries treated as scenery rather than usable terrain — ledges, window frames, railings and rooftops become real routes for flanking or escaping a bad fight. Infinity Ward has been explicit that the goal is physicality and grounded realism rather than the boost-jump movement of the Black Ops 4/Infinite Warfare era: Operators should still feel like soldiers, just ones with more options for approaching an engagement from multiple angles.

3. Ballistic Authority Ties the New Movement to Gunplay

The new movement options only matter if the gunplay keeps up, which is where Ballistic Authority comes in — Infinity Ward's new weapon-first technology stack that unifies aiming, physical handling, audio propagation, visibility and combat perception into a single tuned system. Bloom has been removed from hipfire entirely, and recoil, convergence and weapon handling have been rebuilt to respond more directly to player input rather than randomized patterns.

The practical effect while you're mantling a ledge or sliding around cover is that your weapon is supposed to behave consistently regardless of stance or movement state — what Infinity Ward calls making sure "every shot tells the truth." For the full list of confirmed launch maps, modes and weapon details, our multiplayer breakdown has the complete rundown.

4. A Technical Leap in Visual Fidelity

Modern Warfare 4 is described by Infinity Ward as delivering "the most immersive and technically advanced Call of Duty ever built." That's a marketing line, but the specifics behind it are concrete: industry-leading VFX, lighting, materials and character rendering are built directly into moment-to-moment gameplay rather than reserved for cutscenes, with particular attention paid to readability in dense, high-action scenes — explosions, smoke and atmospherics on maps packed with foliage and enemy combatants.

The game is built natively for current-generation consoles and PC, which Infinity Ward says enables larger combat spaces, more active worlds and more consistent frame-to-frame performance across Campaign, Multiplayer and DMZ. That current-gen-only focus is also the reason PS4 and Xbox One were cut from this release.

5. Infinity Ward and Beenox Go All In on PC

PC gets more dedicated attention than recent entries, with Infinity Ward partnering directly with Beenox to expand how far players can push performance, visual fidelity and customization. On the high-fidelity end, that includes support for DLSS 4.5, expanded real-time ray tracing across all three modes (Campaign, Multiplayer and DMZ), and improved performance on ray-traced reflections, ambient occlusion, shadows and volumetrics.

On the performance end, multiple upscaling and frame-generation options are available to balance image quality against responsiveness, alongside dedicated competitive-focused settings for players who'd rather prioritize frame rate over eye candy. Expanded graphics options sit in between, giving PC players finer control over exactly how the game looks and runs than past Modern Warfare releases offered.

6. Modern Warfare Comes to Nintendo Switch 2 for the First Time in Over a Decade

The biggest platform surprise is Nintendo Switch 2 support. Infinity Ward, working with Digital Legends, is building Modern Warfare 4 natively for the console — the first time a Modern Warfare game has been playable on Nintendo hardware in more than ten years. It's not available at launch alongside the other platforms; Activision has said pre-order details and a release window will be shared later, so Switch 2 owners should watch the official Call of Duty blog for the follow-up post rather than expecting day-one availability.

7. What Changes for Warzone Starting Today

Modern Warfare 4's launch also starts the clock on changes to Call of Duty: Warzone. Season 1 is coming "shortly after" today's release and will begin integrating Modern Warfare 4 content and seasonal progression into Warzone as part of a connected experience between the two games. Until Season 1 arrives, Warzone continues running on its current Black Ops 7 seasonal content.

Separately, Activision has confirmed that Warzone on PlayStation 4 and Xbox One will stop being playable once Season 1 launches, following earlier cutoffs that removed new downloads and, on June 25, the in-game store on those platforms.

Quick Tips for Launch Day

• Confirm your platform before buying — Modern Warfare 4 is current-gen only, with no PS4 or Xbox One version.
• Spend some time in a private match or the firing range getting used to Mantling, Climbing and Hanging before jumping into ranked multiplayer; the added verticality changes common sightlines on every map.
• PC players chasing maximum fidelity should enable DLSS 4.5 and ray tracing from the graphics menu; competitive players should check the dedicated low-latency preset instead.
• Switch 2 owners: there's no release date yet, so hold off on any third-party pre-order listings until Activision posts official details.
• Warzone players should expect Season 1 "shortly" after today — PS4 and Xbox One access ends when it arrives.
