The innovative “Kill Block” map for Call of Duty: Modern Warfare 4 is my most anticipated new feature for the game’s multiplayer — and we finally get to see more of it

Xbox and Activision have broken with tradition and partnered with Fanatics Fest to show off one of the most innovative new maps heading to Call of Duty: Modern Warfare 4 when it launches this October.

Multiplayer map reveals are typically reserved for the annual Call of Duty NEXT event, but a date for the celebration of all things Call of Duty has yet to be confirmed for 2026. Rather than waiting until closer to launch, Infinity Ward will give the public their first look at the new map, “Kill Block”, during Fanatics Fest in New York City from January 16-19.

Call of Duty: Modern Warfare 4 will be playable for those who have purchased tickets to Fanatics Fest at the Javits Center in NYC, and a panel featuring Kevin Durant, Inde Navarrette, Infinity Ward Studio Co-Head Mark Grigsby, and Tyler Bahl will take the stage for an exclusive panel on Call of Duty in Culture on Saturday, July 18.

The original concept behind Kill Block was dreamed up by Multiplayer Creative Director Geoff Smith, who was inspired by the Santiago Bernabéu in Madrid. The stadium is designed to have multiple arena floorings set on a rotating slab, allowing it to shift from a football stadium to a concert venue and back again while maintaining the various fields.

From concept to production, Kill Block eventually evolved into an adaptive training facility with a modular battleground that pieces together different slabs to create hundreds of unique map combinations. Designed to resemble a live-fire training environment, Kill Block is assembled from two end slabs with a central slab that pieces together map sections, both new and from iconic locations seen throughout Modern Warfare’s rich history.

Infinity Ward shared an overview of how the engineering behind Kill Block works in a new blog post.

Engineering a dynamic map for Modern Warfare 4

While Call of Duty is a video game, the team at Infinity Ward takes great pride in the real-world inspiration beyond the pixels. It would be easy enough for the development team to shrug off the hows and whys of the mechanics powering Kill Block as “It’s just a game” and hope that the players could suspend disbelief enough to enjoy themselves. But Infinity Ward doesn’t work that way, and the team has taken the engineering behind Kill Block very seriously.

Kill Block, which is set within the West Bridge Advanced Military Training Facility, is flanked along the perimeter by eight concrete towers that house the electronics, motors, and pulley systems that make the dynamic arena function. The map is functionally the size of the popular Shoot House map from Modern Warfare past, though its continuously evolving layout keeps things fresh with each new round.

The map’s three slabs sit upon a network of rail-mounted wheel assemblies, known as ‘bogies’, that travel along tracks embedded above and below the training area. The map changes at the end of each round of Gunfight. When the active slab decouples from the others, it is lowered to a storage chamber beneath the arena for safekeeping. The motor then selects the new Slab and winches it into position before raising it to the surface. How’s that for combat evolved, Halo?

Each slab effectively takes up one third of Kill Block’s play space, and each one is completely self-contained while maintaining all the necessary openings to flow seamlessly into each other. While each team spawns on their respective endpoint, movement across all three slabs in the combo is unrestrained (and encouraged.)

Some slabs add more than just new buildings, trees, or other obstacles. Some are also fitted with military-grade weather simulation systems — introducing snow flurries, fog, and other conditions that affect not just the look of the map but also weapons.

Kill Block’s slabs are a new way to experience old favorites

Call of Duty as a franchise struggles to walk a tight line between feeding into the nostalgia of its long-time player base while allowing the developers the creative freedom to create fresh and new experiences that might lure new players in. One way the development teams have sought to bridge that gap is with remastered variants of once-popular multiplayer maps.

But leaning into an influx of remasters leaves players looking for something new out in the cold. After 5 different variants of Shipment and Shoothouse, both the fans and the players can find themselves struggling with the threat of Call of Duty fatigue. Kill Block is an interesting solution to that problem, introducing both the chaotic gunplay of a small map without leaning exclusively into the tried-and-true favorites.

Infinity Ward’s multiplayer team has claimed that there are enough assets readily available for Kill Block to support up to 900 combos total, though at launch, players can expect roughly 500 to be live. The following slabs can be expected in the Kill Block rotation at launch, though some names may be changed:

• Ambush (Call of Duty 4: Modern Warfare): A central slab featuring a convoy-clogged main road with blown-out pre-fab buildings on either side, with plenty of sniping opportunities.
• Blacksite (Call of Duty: Modern Warfare II and III): An end slab featuring three prefabricated structures with open access between each of them. Players will find a mud and grass thoroughfare, a rusted van, an open cargo container, and stacked military gabions.
• Killhouse (Call of Duty 4: Modern Warfare): Gabions corner prefab walls with some small gaps for mantling, while a central kill box dots the middle of the map, and small scenic cover opportunities cover the edge of the end slab.
• ME-Town: A central slab featuring a kill box dirt courtyard surrounded by prefabricated structures in each corner. Lots of interior and roof space for sniper nests. The main building is turquoise and features plenty of opportunities for close-quarter combat in its tight rooms and scramble points.
• Snow Block: The fortifications of open cargo containers and concrete blocks offer unique overwatch opportunities to would-be snipers, but there’s a limit to how much cover you can find on this end slab.
• Trench: This central slab is a literal no-man’s land of sunken mud walls and pill boxes with sandbags, tires, and wooden trusses that feel like they’re going to collapse in on your squad without a moment’s notice. This is a fraught middle ground with minimal cover, but good sight lines.

In addition to the confirmed Kill Block slabs, Infinity Ward also teased imagery showing off combos for the dynamic map featuring parts of Station, Shoot House, Woods, and Killhouse. Additional maps and supported modes for Kill Block are expected to be added to the game during Call of Duty: Modern Warfare 4’s seasonal content drops post-launch.

Hands-on impressions of Kill Block

Members of the press and content creators alike were invited to Infinity Ward’s studio for an early hands-on preview of Kill Block in action. During the preview, we were able to play matches of 10v10 Gunfight on Kill Block. The match would begin with the player teams each infilling on their respective end slabs with a loadout that had been randomly assembled by the game.

Gunfight is a round-based, one-life per player core mode, and the first interactions with Kill Block were surprisingly intimidating. There’s an urge to explore the undeniably creative design of Kill Block and to understand all the machinations behind it. But doing so certainly puts you at risk of other players who aren’t so interested in the aesthetics willing to pick you off as an easy target.

When you do get over the desire to ooh-and-aww over what Infinity Ward has managed to create out of Kill Block and decide to focus on the game, you’ll find yourself quickly flung into intense combat against enemy players. As a long-time fan of small map playlists that throw you immediately into the line of danger, I was excited to feel that rush of instant action from Kill Block.

Infinity Ward’s willingness to give fans of small maps something to sink their teeth into had interesting effects on the player base in Modern Warfare 2 (2022). There were considerable complaints on social media by players who felt the time between matches was too long in standard map playlists as players flocked to small map rotations in order to complete grindy camo challenges.

And yet, at the same time, there was a subset of players who love small maps so much they were even requesting Treyarch to introduce IW’s beloved tiny map, Shipment, to the Black Ops series. (They didn’t, but they did take a risk and go even smaller with the chaotic GRWM limited map during April Fools.)

Kill Block feels fresh and exciting and new, but it’s serving multiple purposes for the split fan base that pines for nostalgic gameplay and laments continuous remasters simultaneously. Personally, Kill Block is one of my most anticipated new additions for Call of Duty: Modern Warfare 4.

Call of Duty: Modern Warfare launches on Xbox Series X|S, Xbox on PC, Battle.net, Steam, PlayStation 5, and the Nintendo Switch 2 on October 23, 2026. Players who preorder the game will unlock early access to the Open Beta and up to one week of early access to the Modern Warfare 4 campaign starting on October 16. Modern Warfare 4 is the first Call of Duty title to skip last-gen consoles, and the game will also not be included in Xbox Game Pass subscriptions until Holiday 2027.
