Activision and Infinity Ward reveal “Kill Block,” a new multiplayer map feature for Call of Duty: Modern Warfare 4, during Fanatics Fest. The map is set at the fictional West Bridge Advanced Military Training Facility, where the battleground reconfigures between matches. Activision describes Kill Block as a modular design built from three swap-ready sections—or “slabs”—that detach after each game and reconnect into a new layout for the next match. The full playable area matches the size of the 2019 Modern Warfare’s Shoot House, and the three-slab structure includes two outer “end slabs” and one central combat slab. Activision says there are more than 500 possible “combo” configurations at launch, created by randomly combining the modular pieces. The design uses new sections while also incorporating parts from earlier Call of Duty maps, such as elements associated with Ambush (Call of Duty 4: Modern Warfare), Storage Town (Warzone’s Verdansk), and Highrise (2009’s Modern Warfare 2). To help players navigate the changing environment, the map includes labeled perimeter sectors for callouts. Kill Block supports 2v2 Gunfight and larger modes including 3v3 and Gunfight 10v10 at launch, with more multiplayer coverage planned. Modern Warfare 4 launches October 23 for PC, PS5, Xbox Series X|S, and Switch 2.
