MW4 August 31 Beta Update: TTK, Playlists, XP and 11 Weapons

Quick answer

The official August 31, 2026 MW4 Beta update changes the current test boundary. It adjusts TTK and Resurgence, enables Double XP and Double Weapon XP, adds Transit 213 24/7 and Kill Block 6v6 Gunfight, and changes 11 weapons. These are Beta values, not an October 23 launch guarantee.

What changed

• TTK and Resurgence rules changed.
• Double XP and Double Weapon XP are active.
• Transit 213 24/7 and Kill Block 6v6 Gunfight add repeatable playlist samples.
• Krait P68, PPSh-41, ISO Nightshade, FiNN LMG, Type 73, Oris 8.6, Han 86, Axion, Hyeon Burst, M4 Hurricane and Rezi 12 were changed.

Why old rankings no longer settle the answer

An August 22 or August 29 score mixes different damage, movement, playlist and progression conditions with the August 31 ruleset. Treat earlier boards as dated history and compare affected weapons again under one current mode and attachment set.

How to retest

1. Record the August 31 date, playlist and weapon conversion before testing.
2. Run one close, one mid-range and one long sightline with the same attachments.
3. Log shots to finish, hit rate, reload exposure and playlist.
4. Keep Resurgence and Gunfight results separate from a universal ranking.

What remains unknown

The patch does not establish final launch balance, complete damage curves, a permanent tier order or whether these values will survive later Beta updates.

FAQ

Is ISO Nightshade still officially number one?

No official ranking exists. Its earlier community lead must be retested because the August 31 notes changed it.

Does Double XP change weapon strength?

No. It changes progression speed, so record it separately from combat performance.
