Certain Slabs also introduce simulated rain or snow that affects visibility. Players should check the current conditions before relying on a distant firing position. If no team is eliminated before time expires, an Overtime Flag will appear. If you keep it, you win the round . The remaining players have to consider paths that get them to the objective . Teams should approach or observe these routes from cover and avoid unnecessary exposure. If no one captures by the end of overtime, the team with the health advantage wins. You use AI every day.

First round: Read the centre and nearby cover
Kill Block changes every two rounds in Modern Warfare 4. Kill Block will launch with 3v3 and 10v10 Gunfight modes, with over 500 potential configurations. Because neighbouring sections can change. A useful opening approach is to identify how the Central Slab connects to the starting area, however, recognising a familiar location doesn’t reveal the full layout. Because it often brings opponents together from several directions. Players should check the nearby entrances and cover before moving on, the supplied Xbox Wire guide recommends learning this section first.
The map is set at the West Bridge Advanced Military Training Facility and has three interlocking sections that combine into different layouts, routes, cover, and sightlines throughout a Gunfight match. Everyone gets the same randomly assigned weapons and equipment, so positioning and teamwork matter when facing an unfamiliar setup. Understanding when the sections move, how the central area connects them, and when to approach the overtime objective can help teams adjust without spending each round exploring the entire map. The match is repetitive: teams play one round and swap sides for the second, then get a different layout and loadout. This gives players two rounds to learn each setup before starting over. Each player has one life per round and the first team to win six rounds wins the match. These are the rules as written in the official Call of Duty Kill Block guide: Kill Block has two outer sections, called End Slabs, and a middle section called the Central Slab. Their arrangement determines the paths between spawn areas, available cover and angles from which opponents can attack. Some sections recreate parts of Crash, Storage Town and Shoot House. Reference points are trucks, concrete barriers and wrecked vehicles and walls, while signs, arrows and numbers help teammates describe enemy positions. Rooftops, containers and balconies offer longer views but also leave players exposed. Teams should check surrounding angles before occupying elevated positions. The layout stays the same when teams swap starting positions. Use this round to review the routes their opponents used and reconsider any firing positions that proved vulnerable. Doors offer additional options: you can open them slowly, force them open, or shoot them open. Choose an approach that suits the situation, especially when a noisy entry could reveal a player’s position. Rounds three, five and subsequent resets introduce another combination of Slabs alongside a fresh shared loadout. Players should reassess their approach instead of repeating a successful route from the previous arrangement. A close-range weapon may favour covered approaches, while a long-range weapon makes clear sightlines more useful. Teammates can split attention between entrances instead of watching the same route.
