The MW4 Season 1 patch notes, published November 5, 2026, change 17 guns and most of them gain. The Oris 8.6, Wz.55 Striga, M4 and Rezi 12 get clear buffs, while the APOC-338, VEL 46 and Hyeon Burst’s Hyperburst Apex lose ground. Hardcore health drops from 30 to 22, and DMZ adds the X01 zone.
This page covers the weapon balance changes listed by Infinity Ward, then the killstreak, Hardcore, progression and DMZ changes. New to the season? Our MW4 Season 1 new weapons guide covers how to unlock the Cronen Osprey and CSG-35.
MW4 Season 1 weapon changes: every gun in one table
All figures below come from Infinity Ward’s Season 1 patch notes. Ranges are in metres, and “medium” means the damage tier between maximum and minimum. Stats that the notes list as unchanged are left out.
| Weapon | Class | What changed |
|---|---|---|
| Axion | AR | Medium range 34.8 → 38.61; muzzle velocity 415 → 470 m/s |
| Han 86 | AR | Head multiplier 1.25 → 1.3 |
| Hyeon Burst | AR | Medium damage 24 → 25 |
| Hyeon Burst, Hyperburst Apex | AR | Max damage 30 → 23; max range 24.64 → 30.99; minimum damage 25 → 20; medium tier (28 damage, 36.58 m) removed |
| Kastov 762 | AR | Medium damage 24 → 25; medium range 40.13 → 42.16; head 1.33 → 1.35; neck and upper torso 1.08 → 1.1 |
| M4 | AR | Max range 25.91 → 27.94; head 1.25 → 1.3 |
| M4, Hurricane Apex | AR | Max range 10.49 → 11.68 |
| Patriot XMR | AR | Max range 31.24 → 33.53; ADS move speed 2.22 → 2.26 m/s |
| ISO Nightshade | SMG | Max range 10.54 → 11.68; minimum damage 13 → 14 |
| PPSh-41 | SMG | Second medium damage 13 → 14; minimum damage 12 → 13 |
| VEL 46 | SMG | Max range 10.13 → 9.65; medium ranges 17.27 → 16.51 and 25.15 → 24.13; minimum damage 13 → 14 |
| Wz.55 Striga | SMG | Max damage 26 → 27; minimum damage 17 → 19; second medium tier (18 damage, 30.23 m) removed; head 1.3 → 1.4 |
| X-58 Nyx | SMG | Second medium damage 15 → 16; minimum damage 13 → 14 |
| APOC-338 | LMG | Minimum damage 33 → 32; head 1.35 → 1.3 |
| Type 73 | LMG | Max range 24.89 → 25.53; head 1.25 → 1.3 |
| Type 73, Assault Apex | LMG | Max range 22.23 → 24.13; medium damage 22 → 23; medium range 41.91 → 43.13 |
| Rezi 12 | Shotgun | Medium ranges 4.57 → 4.95, 6.35 → 6.86 and 8.76 → 10.29; minimum damage 14 → 16 |
| Rezi 12, Enforcer Apex | Shotgun | Medium ranges 5.08 → 5.33 and 7.37 → 7.87; minimum damage 19 → 20 |
| Mosin-Nagant | Marksman | Max range 36.83 → 40.13 |
| Oris 8.6 | Marksman | Max range 19.05 → 22.61; minimum damage 58 → 63 |
| Krait P68 | Pistol | Max range 8.89 → 9.4; medium range 20.32 → 21.08; lower torso 1 → 1.1 |
Two entries in the official table look off, so we did not build anything on them. The Mosin-Nagant’s damage rows are printed in metres, so we kept only its maximum damage range. The PPSh-41’s first medium damage row shows 15 → 15 with an 8% increase, so its actual change there is unconfirmed. Neither had been corrected as of November 6.
Season patches like this one can move a gun you ignored back into your class. If one of the buffed guns is still low level, MW4 weapon leveling is the shortcut, and our guide to unlocking attachments covers the free route.

Three items take a real cut. Infinity Ward does not explain the reasoning gun by gun, and the notes do not publish time-to-kill figures, so this is only what the numbers say.
- Hyperburst Apex (Hyeon Burst): the biggest change in the table. It loses seven points of max damage and its medium tier, but keeps its top damage out to a longer range. Hyperburst already lost full-auto damage in the October 28 update.
- APOC-338: small cuts to minimum damage and headshots, also after an October 28 trim.
- VEL 46: all three damage ranges shrink by a few percent. It gets one point of minimum damage back.
Hardcore health, killstreaks and equipment changes
The late addition to the notes is the one Hardcore players will feel most: maximum health in Hardcore modes falls from 30 to 22. These are the other multiplayer gameplay changes with numbers:
| Item | Change |
|---|---|
| Argonaut | Health 800 → 1,200 |
| Crossfire | Spawn protection added; bullet radius down 25%; bullet damage down 50%; less camera shake while flying |
| Prox Mine | Arming time 1.5 → 0.75 seconds |
| Claymore | Arming time 1 → 0.75 seconds; forward trigger range 2.29 → 3.18 m; trigger cone 60° → 80° |
Battle Hardened also no longer gives full immunity to Shock Sticks, because that was a bug. The fix means it now only reduces their effects.
New maps, modes and guns in the Season 1 notes
The launch lineup matches what Activision announced on October 28. Backstab, Canyon, Shoot House and Kill Block: Crash join the rotation, with Grind and Drop Zone as the returning modes. Our Season 1 maps guide has the layouts.
The notes add one useful detail: the Wager Match event and Gauntlet 1v1 are marked “Coming Soon”, so neither is part of launch day. No date is given. Our Wager Match guide explains how it will work. Threat Briefing: Battle Tank is the event listed as running now.
Camo, progression and console fixes in Season 1
- Mercurial Drift: fixed the Multiplayer Mastery Camo staying locked after you finished its requirements.
- Boksu Prime: now unlocks after completing the Classic Prestige 10 Track.
- 120Hz on console: Performance Mode (120Hz) is open to all PS5 and Xbox Series X|S players with 120Hz displays, with or without VRR. Infinity Ward still recommends VRR.
- Search and Destroy: fixed defusing the bomb from an unintended distance.
- Hijack: several fixes to respawns, Spike planting and resets, team spawns and upload stats.
Both the MW4 and Warzone notes carry the same notice about Warzone Agent, an unauthorized lobby-shopping app. The rules and the rest of the Warzone update are in our Warzone Season 1 patch notes guide.
MW4 DMZ Season 1 changes: X01, Possum and XP
DMZ’s headline addition is X01, an underground GRANIT Arms site you reach through Hajin. Most of its details are still marked classified in the notes, and our DMZ X01 guide has what Activision has shared. The balance changes that affect your runs are these:
- Weapon XP: lowered for vehicle kills against enemy AI. XP from Operator kills is unchanged.
- Possum: the squad that killed you must be 2.5x farther away before you can activate it, and the failsafe timer goes from 4 to 5 minutes.
- Supplied Drops: now applies to Dynamic Operations crates, and its chance of an extra container rises from 25% to 50%.
- Crossfire: more damage to vehicles, with a larger increase against enemy tanks.
- Batteries: lower spawn rates at Banks.
- Exploits: “various duplication exploits” fixed, with no details given.
- Camo fixes: Lieutenant Dog Tags now count toward Camo Challenge progress, and squad events count toward DMZ Mastery II.
