Call of Duty: Modern Warfare 4 Season 1 Update 1.112 — Every Warzone Change Explained

Call of Duty: Modern Warfare 4's first season has only been live for a week, and Infinity Ward has already shipped a follow-up patch to tighten it up. Update 1.112, released November 10, 2026, is the first version-number change since Season 1 launched on November 6, and it arrives alongside a new anti-cheat enforcement wave in Warzone and an expanded Performance Mode rollout for console players.

Here's everything confirmed in Modern Warfare 4 and Warzone Season 1 so far, what Update 1.112 specifically fixes, and how it all fits together now that the series has moved on from Black Ops 7. This is the first full season built around Modern Warfare 4 since launch, so a lot of the Season 1 patch notes are still being folded into weekly hotfixes like this one.

1. What Update 1.112 Changes

Update 1.112 is a required download for Modern Warfare 4 and Warzone, bundled with Multiplayer Pack 1.004 and Shared Content Pack 1.036. According to the official patch notes, the headline gameplay change is a smoother ADS (aim-down-sights) sensitivity transition: the game now shifts back to hip-fire sensitivity sooner after a player releases ADS, which should make flick-shots and quick re-centers feel less delayed on both Multiplayer and Warzone.

The rest of 1.112 is a stability and bug-fix pass across Multiplayer, Warzone, and DMZ, cleaning up issues that surfaced during Season 1's first few days.

2. Warzone Agent: A New Layer of Anti-Cheat Enforcement

Starting with Season 1, Call of Duty is actively enforcing against an unauthorized third-party tool referred to in the patch notes as "Warzone Agent." Players who have it running are blocked from accessing Multiplayer modes until it's closed, and anyone caught trying to circumvent the block risks a temporary or permanent ban. Campaign access is not affected by this enforcement.

This is separate from Update 1.112 itself but was formalized as part of the same Season 1 patch notes rollout, and it's worth flagging for anyone who's modified their client with third-party overlays or utilities.

3. Performance Mode Expands to PS5 and Xbox Series X|S

Also tied to the Season 1 notes: Performance Mode, which targets a 120Hz refresh rate, is now available to PlayStation 5 and Xbox Series X|S players with a 120Hz-capable display, regardless of whether their specific TV or monitor supports VRR. Previously this option was more restricted, so console players chasing the smoothest possible frame pacing in Warzone should check their display settings menu after installing 1.112.

4. The Two New Season 1 Weapons: Cronen Osprey and CSG-35

Season 1 launched with two new base weapons, both usable in Multiplayer, Warzone, and DMZ:

• Cronen Osprey — an assault rifle, available as an instant Battle Pass unlock.
• CSG-35 — a submachine gun, also part of the Season 1 Battle Pass track.

Infinity Ward has said two more weapons are planned to arrive later in the season, in addition to these two. Update 1.112 specifically fixes a tracking bug for both guns: Platinum camo challenges for the Cronen Osprey and CSG-35 weren't registering progress correctly before this patch, which is now resolved.

5. New and Returning Multiplayer Maps

Season 1's 6v6 core map rotation includes three confirmed additions on top of the launch map pool:

Backstab

A snow-covered town map built around a central fenced yard, abandoned tanks, and a mix of long sightlines down the main street versus close-quarters fights inside the surrounding buildings.

Canyon

A sun-scorched desert map split by a river, with players able to push through the Convoy Ambush area near the water or take the elevated Cliff Path for a different angle on the fight.

Shoot House

A returning fan-favorite, rebuilt for Modern Warfare 4 around an NK Shoot House facility, with a junkyard, interior tunnels, and overhead positions on the Hospital and Apartment buildings.

Infinity Ward also added a Shransit playlist combining Shipment, Shoot House, and Transit 213 into one rotation, with a Hardcore variant available through Quickplay.

6. Full List of Bug Fixes in Update 1.112

Beyond the ADS sensitivity tweak and the camo-tracking fix already covered above, Update 1.112's Warzone and Multiplayer notes list the following corrections:

• Fixed several stability issues and crashes across Modern Warfare 4 and Warzone.
• Fixed the pause menu closing unexpectedly when held open for a few seconds mid-match, which left players without a HUD.
• Fixed being unable to edit Loadouts that included a Legacy weapon.
• Fixed the wrong sound effect playing when picking up a Classified Weapon from a Public Event crate.
• Fixed squad widget icons sometimes overlapping on-screen.
• Fixed mouse-and-keyboard players being unable to open the Match Summary screen while spectating.
• Fixed Play Again and Leave Match options sometimes failing to appear after a team is eliminated.
• Fixed the Rally Point kill-milestone reward crate sometimes not spawning.
• Fixed item quantity and price text overlapping in the Buy Station menu.

On the Multiplayer and DMZ side, the same patch also adjusted Ghost Perk and enemy nameplate visibility, enabled match-wide chat in Free for All and Gun Game, and added cash rewards for failed DMZ exfils based on looted item value and deployment time.

7. What Else Is Coming Later in Season 1

A few Season 1 features are confirmed but not fully live yet. Gauntlet 1v1, a new Multiplayer mode, is listed as "Coming Soon," alongside a Wager Match playlist tied to Warzone-related challenges and events. Infinity Ward has also confirmed more maps, modes, weapons, and events will roll out at mid-season, on top of what launched on November 6.

On the DMZ side, Season 1 opened X01, an underground GRANIT Arms facility accessible through the Hajin location, bringing new Orders, threats, and equipment to extract against. DMZ also picked up a new mechanic: players now earn cash rewards for failed extractions based on the value of their looted items and how long they survived, outside of Story Missions.

None of this is final — Infinity Ward's own roadmap language around mid-season content is intentionally vague, and exact dates for Gauntlet 1v1 and Wager Match haven't been published yet. Treat anything beyond what's listed in the official patch notes as subject to change.

8. Quick Tips Recap

• Update 1.112 is mandatory — you can't play online until it's installed.
• Close any unauthorized third-party overlay tools before queuing into Multiplayer or Warzone, or you'll be locked out under the new Warzone Agent enforcement.
• PS5 and Xbox Series X|S players with a 120Hz display can now enable Performance Mode even without VRR support.
• If your Cronen Osprey or CSG-35 Platinum camo progress looked stuck before November 10, it should now track correctly.
• Check out the Shransit Quickplay playlist if you want Shipment, Shoot House, and Transit 213 without queuing them individually.
