Launch Multiplayer maps confirmed; Shipment follows October 27

The October 21 announcement lists 12 Core 6v6 maps, three 32v32 Ground War maps and four 2v2 Gunfight maps for the October 23 launch. Kill Block separately supports 3v3 and 10v10 Gunfight. Shipment is scheduled for October 27, so it is not in the day-one 6v6 set. New modes include cash-collection Inflation, Data Spike delivery in Hijack, the buy-phase tactical mode Collateral, and Ground War’s Combat Outpost. Proving Grounds provides movement tutorials and timed courses. Possession and Infected are announced for the pre-Season 1 Halloween period, without a specific date in this article. These are Multiplayer details, separate from Stranded campaign puzzles and Hajin DMZ. The current status above links the later October 23 worldwide launch confirmation.

Known Multiplayer issues: Loadouts and missing stats

Official support updated ; checked . Both notices apply to all platforms.

Why won’t my MW4 Multiplayer Loadouts save?

Activision’s October 22 known-issues update, checked October 23, lists Multiplayer Loadouts not saving on all platforms as under investigation. It does not provide a workaround or a fix date. The earlier Gunsmith rule about manually saving a weapon build does not establish a fix for this separate Loadout-saving issue.

Why are my MW4 stats missing from Combat Record or Leaderboards?

The same October 22 support update lists stats not appearing in Combat Record and Leaderboards on all platforms. Activision describes this as a display issue and says stats are still being tracked. The notice does not give a restoration time; missing displayed stats are not evidence that the underlying match stats have stopped being recorded.
