Call of Duty: Modern Warfare 4 – Kill Block is Must-Play Multiplayer at Launch

Hidden inside the West Bridge Advanced Military Training Facility is a complex combat environment where shifting, modular battlegrounds challenge even the most elite Operators, with hundreds of unique configurations. This is Kill Block, and if you’re picking up Call of Duty: Modern Warfare 4 today, you must play it – it’s one of the most inventive and fun maps to come to Call of Duty Multiplayer in years.

The way it works is this: Kill Block is a Multiplayer map that reconfigures every match, challenging you to rethink routes, sightlines, and combat spaces on the fly. And right when you think you’ve got it figured out, the Slabs switch again.

The Training Facility is made up of three modular sections: two outer areas known as End Slabs and one central space known as Central Slab. These combine into new combat configurations after each match, and how each section is positioned allows for multiple variants, creating hundreds of unique layout combinations.

As noted on the Call of Duty Blog, most map sections are entirely new, while others draw inspiration from iconic locations across Modern Warfare history. More than 500 configurations are possible at launch, with layouts changing between matches and throughout rounds to transform cover placement and pacing, supporting both 3v3 and the new 10v10 Gunfight mode at launch, with future support planned for more core Multiplayer modes. It’s an ever-changing map that enables teams to experience a variety of environments across numerous combat scenarios.

I got a taste of Kill Block last month during the Modern Warfare 4 Beta and found this constant cycle of combat a refreshing challenge – having to adapt to a changing map between rounds made it feel like teams were on an even footing, each trying to make note of corners and discover ideal spots to post up on defense as quickly as possible. And now with its wide release today for the launch of Modern Warfare 4, I can’t wait to dive back in.

Finding the Connection

When jumping into a Kill Block match, you can expect to see a wide variety of environments from urban streets, military compounds, shipping containers, and more. It’s designed to function as a tactical set, each with its own layouts to master and spaces to navigate coupled with changing vantage points, chokepoints, low openings, and more that extend into each adjacent Slab – and occasionally across the entire map.

One of the strategies I employed during my hands-on time was to get familiar with the Central Slab first. Because those are always linked with the adjacent slabs, the central area of the map would typically offer scenery crafted to enhance combat coming in from multiple angles – these were almost always the primary encounter points against other teams to rack up eliminations. While it’s tempting to try and rush through and get a sense of the entire randomly generated layout, focusing on the Central Slab and working out from there was usually an ideal strategy I found.

Another observation is that each of the Slabs are rectangular in shape, and often a familiar footprint; self-contained, but with the necessary openings to allow for effective match flow into adjacent Slabs. And there was almost always an opportunity for cover, like parked trucks, burned-out tanks and cars, concrete blocks, barriers, and walls, and a few tactically important doors you can shoot open, barge through or open slowly with stealth in mind. There’s also plenty of markers to take note of to jog your memory if you’ve played through a Slab before, so make sure you take mental notes for construction signs, grenade marks, arrows, numbers, and others to assist in your spatial awareness as you learn the environments.

As touched on earlier, the Call of Duty Blog confirmed that while most Slabs are entirely new, others recreate iconic locations including Crash from Call of Duty 4: Modern Warfare (2007), Storage Town from Call of Duty: Warzone’s Verdansk map, and Shoot House from Modern Warfare (2019). Though drawn from iconic maps, these Slabs are fundamentally changed by the randomized areas around them, allowing for terrain to deliver both classic and new tactical experiences, which is going to be a lot of fun.

What’s also fun is that these Slabs are “fitted with military-grade weather simulation arrays” that can introduce the possibility of rain or snow that can impact visibility and other tactical conditions in Kill Block. And let’s not forget Modern Warfare 4’s refined and fluid movement mechanics, allowing you to skirmish as you would during a core Multiplayer match. This includes being able to climb on rooftops, containers, and balconies, and ascending to other areas that offer valuable sightlines at the expense of exposure.

Gunfight’s Return

Kill Block will launch alongside an expanded Gunfight experience, featuring both 3v3 and the all-new 10v10 mode. What makes this mode fun is that every round a team is pit against another in single-life combat, with all players equipped with the same randomly assigned weapons and equipment – my favorite is when everyone starts with an RPG, creating a fast-paced and hectic clash (with lots of explosions, of course).

During Gunfight on Kill Block, teams swap sides after the first round. After round two, the three Slabs shift to a new combo and players receive another random loadout. The combo changes every two rounds until one team reaches six wins. There are no custom loadouts to rely on in Gunfight, placing the emphasis squarely on teamwork, weapon proficiency, and tactics. If neither team is eliminated before the end of the round, an Overtime Flag deploys, forcing both teams to converge and capture it to claim victory.

While Gunfight 3v3 and 10v10 headlines Kill Block at launch, we’re told the West Bridge Advanced Military Training Facility will be capable of supporting additional core Multiplayer modes in post-launch seasons, giving us fresh tactical challenges across an expanding variety of Multiplayer modes in the months to come.

Beyond the Block: The Complete Multiplayer Offering

From Kill Block’s adaptive battlegrounds to globe-spanning core Multiplayer maps, large-scale Ground War, tactical one-life modes, classic respawn playlists, and party modes, Call of Duty: Modern Warfare 4 Multiplayer offers something for every playstyle.

Beyond Kill Block, players can expect 12 grounded Multiplayer maps spanning diverse global locations, each with a distinct visual identity and tactical flow, plus two returning favorites shortly after launch. From a Korean fishing village after an amphibious assault, to the top of a snow-covered New York hotel, and a fugitive’s hideout in a dense residential district, the visual diversity on display in Modern Warfare 4 is something special.

On top of that, we’ll have larger-scale battles with armored vehicles across expansive maps in Ground War, featuring brutally intense combined-arms warfare, as well as a quartet of smaller, Gunfight maps, a full suite of Multiplayer modes and Hardcore variants, including favorites like Team Deathmatch, Domination, Hardpoint, and more. Whether you favor playing the objective, squad tactics, or pure eliminations, there’s bound to be a mode for your playstyle.

Call of Duty: Modern Warfare 4 is available today for XBOX Series X|S and XBOX on PC. Play it on console and PC at no additional cost with XBOX Play Anywhere. Also available on Steam, Battle.net, Nintendo Switch 2, and PlayStation 5.

War erupts on the Korean Peninsula as North Korea launches a full-scale invasion that threatens to destabilize the world in Call of Duty®: Modern Warfare® 4.

A young squad of South Korean soldiers fight to survive on the collapsing front lines, while half a world away a vengeful Captain Price wages a personal war from the shadows as he stays one step ahead of those hunting him. As Price’s off-book mission collides with the forces behind the invasion, the war spreads beyond anyone’s control.

Modern Warfare® 4 pushes the series into darker and more dangerous territory, where consequence and escalation bring long-running storylines to a powerful and emotional breaking point.

– Campaign drops players into trench warfare in Korea, close-quarters combat in New York, high-octane chases through Paris, SAS night raids in Mumbai, and city-wide assaults to reclaim occupied territory.
– Multiplayer delivers grounded, precise combat where fluid movement, player choice, and greater control define every engagement.
– In DMZ, players operate as an off-the-books asset behind enemy lines, where every extraction run into contested territory forces hard choices about which objectives to pursue, what to secure, and when to get out.
