Activision is showing off Call of Duty: Modern Warfare 4 multiplayer map dubbed Kill Block, where the landscape changes with every round of a multiplayer match.
I’ve played the new map with members of the press and it’s fun. Now Fanatics Fest attendees are among the first members of the public experiencing Kill Block. Here’s a closer look at the adaptive multiplayer battleground and how it fits into Modern Warfare 4’s broader multiplayer offering.
Fanatics Fest NYC takes place July 16–19 at New York City’s Javits Center, and attendees are the first members of the public to experience Kill Block. As players battle across the adaptive training facility, Activision is revealing more about the Gunfight experiences for Kill Block.
Every round pits teams against one another in fast-paced, single-life combat with every
elimination carrying weight and every surviving teammate influencing a round outcome. Communicate effectively, capitalize on opportunities, and execute under pressure to claim victory.
Each round begins with all operators equipped with the same randomized primary and secondary weapons, tactical and lethal equipment, ensuring every player starts on equal footing. There are no custom loadouts to rely on, placing the emphasis squarely on teamwork, weapon proficiency, and tactical decision making. If neither team is eliminated before the round
timer expires, an Overtime Flag deploys into the combat zone, forcing both teams to converge on it. Capture this Flag to claim victory or fight to maintain the health advantage if time runs out.
During Kill Block Gunfight matches, teams swap sides after the first round. After the second round ends, the three slabs change to a new Combo (map), a new random loadout is equipped, and the match continues. Combos continue to change every two rounds until one of the teams wins six rounds.
How Kill Block works
In the game, players fight it out in team duels in a place where the facility’s massive modular slabs move into place, changing with each round and providing new tactical opportunities in the environment where players encounter it fresh. That means there’s no advantage to the player who has memorized maps and figured out the best places to ambush players.
Instead, the Kill Block map brings out the best skill in players who have to outthink and outshoot their opponents in real time.
Kill Block is an adaptive live-fire training environment where players can square off in multiplayer matches of Gunfight mode, where three human players square off against three others (3v3) or in 10v10 battles.
It takes place in a venue dubbed the West Bridge Advanced Military Training — codenamed Kill Block — an off-the-books facility specializing in modular multiplayer battlegrounds centered on reconfiguring combat layouts. Designed as a live-fire training environment, Kill Block maps reconfigure between matches, forcing players to reassess sightlines, routes, and combat
spaces.
At its core, Kill Block is assembled from three modular sections — two outer areas (“End Slabs”) and one central combat space (“Central Slab”) — that combine into a new combat configuration after each match called a “Combo”.
Each section and how they are positioned allows for multiple possible Combo variants, creating hundreds of unique layout combinations that reshape combat flow.
Most map sections are entirely new, while others draw inspiration from iconic locations across Modern Warfare history. At launch on October 23, 2026, Call of Duty: Modern Warfare 4 will have a Kill Block map with more than 500 configurations are possible, with layouts reconfiguring between matches and throughout Gunfight rounds to transform sightlines, routes, cover placement, and engagement pacing.
Kill Block supports expanded Gunfight experiences, including 3v3 and the new Gunfight 10v10 mode at launch, with future support planned for more core multiplayer modes. The perimeter of the facilities features eight massive concrete towers that house an array of electronics, motors, and pulley systems.
These are attached to three massive steel-reinforced slabs that sit within the facility’s perimeter, each resting on a network of rail-mounted wheel assemblies known as bogies that travel along tracks embedded above and below the training area.
When a change of map occurs between matches, the active slab decouples from the others and is slowly lowered by electric motors into a dedicated storage chamber beneath the arena. A synchronized motor array then switches the rail network to a different slab, which is winched into position and locked in place, transforming the combat space for the next exercise.
The result is an ever-changing Combo map that enables Tier One Operator teams to experience a variety of Shoothouse-style environments across numerous combat scenarios.
Among the slabs, you can find parked trucks, burned-out tanks and cars, stacked gabions, cargo containers, live-fire training rooms, prefabricated multi-level buildings, concrete blocks,
barriers, and walls, and a few tactically important doors you can shoot open, barge through or open slowly with stealth in mind.
Construction markings, grenade marks, arrows, named labels for each slab, training
targets, named rooms (using duct tape floor markers), number markings, and a host of other scenic elements are there to assist in your spatial awareness as you learn the environments. The result of the reconfigurations are new vantage points, chokepoints and defensive positions.
Certain slabs are fitted with military-grade weather simulation arrays along with powerful fans that propel vast quantities of misting water or snow across the slab’s entirety. With inclement conditions and the possibility of rain or snow flurries, Operators need to adapt to shifting visibility, altering sightlines, and other evolving tactical conditions. Expect weapons to also
react to the weather, with ice particles or a wet sheen building up on the weapon until you swap armaments or reload. These spaces can be paired with iconic locations throughout Call of Duty history, such as Call of Duty: Warzone’s Verdansk map and Shoot House from Modern
Warfare (2019).
Paired with different neighboring slabs, these familiar spaces can be played in entirely new ways. Though drawn from iconic maps, these Slabs are fundamentally recontextualized by the randomized environments surrounding them, allowing familiar terrain to deliver both the classic
moments you remember and entirely new tactical experiences. Your job is to learn and adapt.
As you learn the layouts of the different slabs, you’re able to tactically piece together sightlines that carry across the entire Kill Block space itself. It’s worth remembering there are spray-painted signs branding a wall that names most slabs, as well as the names of each slab appearing during the infil as the map reconfigures between matches, enabling you to quickly
ascertain which slabs you’re playing on and learn their layouts the longer you play.
Furthermore, with Modern Warfare 4’s full suite of refined and fluid movement mechanics, you can expect to be able to scramble across slab scenery with the same rapid dexterity as you would during a core multiplayer match. This includes vertical positioning: climbing onto rooftops, atop containers, onto upper balconies, and ascending to other areas that offer advantageous sightlines at the expense of exposure. Kill Block’s adaptive multiplayer maps have been designed to offer tactical benefits and creative challenges no matter where you’re positioned.
Alongside Kill Block, players can look forward to:
- 12 grounded Core multiplayer maps set across globally diverse locations, each built around distinct visual identities and tactical flow, with two additional favorites dropping just after launch.
- Every Core map features its own custom insignia and visual branding inspired by the location, operation, or conflict surrounding the environment, from Lotus (a Korean fishing village in the aftermath of an amphibious assault) to Rooftops (the snow-lined rooftops of a New York Hotel) and Mumbai (a fugitive’s hideout inside a dense residential district).
- Larger scale battles with armored vehicles across expansive maps, featuring brutally intense combined-arms warfare.
- A full suite of Multiplayer Modes and Hardcore variants, from fan favorites like Team Deathmatch, Domination and Hardpoint to new modes with full reveals in the weeks to come.
- Expect Party Modes to also arrive at launch, with additional modes coming shortly after release.
Whether you prefer chasing the objective, coordinating with your squad, or simply racking up eliminations, there’s a mode built to match your playstyle. Preorders are available now at participating retailers, in-game, on platform stores, or at CallofDuty.com.
Call of Duty: Modern Warfare 4 development is led by Infinity Ward and will be available globally on Xbox Series X|S, PlayStation 5 and PC via Battle.net, XBOX on PC, Steam, and Nintendo Switch 2 on Friday, October 23, 2026.
