MW4 Multiplayer

Modern Warfare 4's multiplayer opens to everyone on October 23 — 20 launch maps across 6v6, Ground War, Gunfight, and Kill Block, plus a Create-a-Class system built on beta feedback.

Launch: Oct 23, 2026 Launch maps: 20 Core: 6v6 CaC unlocks: Level 4

MW4 multiplayer goes live October 23 with 20 maps: 12 core 6v6, 3 Ground War, 4 Gunfight, and Kill Block. There's no MP early access — the beta was the preview — but the launch patch applied weeks of beta balance changes to weapons, movement, and spawns. Create-a-Class unlocks at Player Level 4.

Launch map pool — 20 maps

Playlist	Count	Notes
Core 6v6	12	The standard rotation — TDM, Domination, Hardpoint, etc.
Ground War	3	Large-scale maps with vehicles and big player counts
Gunfight	4	Small 2v2 arenas, rotating loadouts
Kill Block	1	New party-style mode space

Modes at launch

A dozen-plus modes across playlists. The core rotation covers the usual Call of Duty staples — Team Deathmatch, Domination, Kill Confirmed, Hardpoint, Search & Destroy — plus Ground War for large-scale play, Gunfight for 2v2 duels, and Kill Block. Expect the playlist rotation to shift weekly post-launch.

Create-a-Class & leveling

Player Level 4 unlocks Create-a-Class — until then you pick from preset loadouts.
Weapon leveling feeds attachments; XP earned across MP (and DMZ) contributes.
Overkill perk is required to run two primaries in MP — slot it if your build needs a primary secondary.
Campaign rewards: finishing the campaign grants free MP unlocks — worth doing if you have early access.

What the launch patch changed

Weapons: tuning pass across the sandbox from beta data — expect early "best gun" lists to shift fast.
Movement: adjustments to how sprint/slide flow into fights.
Spawns: reworked spawn logic based on beta complaints about trapping.
Maps: polish and flow fixes before the 20-map launch.
