Activision recently shared the full patch notes for Season 1 of Call of Duty: Modern Warfare 4 (MW4). The game enjoyed a strong global launch a couple of weeks ago. Reviewers published positive critical reviews. Moreover, early access players heavily praised the campaign and DMZ modes.
However, Infinity Ward continuously tweaked the core experience. For example, developers removed controversial real-world video footage of the 2022 Itaewon Disaster. Additionally, the team nerfed the popular DMZ “possum” perk based on player data. Players previously used this perk to instantly take revenge on attackers. Consequently, the game now blocks self-revives for four minutes or while the enemy player or team remains in the area. Now, Season 1 brings even more adjustments, operators, weapons, and game modes.
MW4 Season 1 Patch Includes Major Weapon Changes & Apex Attachments
Season 1 introduces a major balance sweep across all weapon categories. Most weapons received upward adjustments and buffs. However, developers issued a few notable nerfs. The APOC-338 LMG suffered reductions to its minimum damage and headshot damage. Similarly, the VEL 46 SMG lost a slight amount of ranged damage.


Furthermore, Apex Attachments finally return to the game. Players noticed these attachments missing at launch. Activision clarified that the beta merely tested them early in preparation for Season 1. Consequently, the latest patch notes adjust specific weapons utilizing these equipped attachments. Affected weapons include the Rezi 12 Shotgun, Type 73 LMG, M4, and Hyeon Burst Assault Rifles.
Full Warzone Integration & New Maps
Season 1 finally delivers a fully integrated Call of Duty Warzone experience. Therefore, players can access all 33 Modern Warfare 4 launch and Season 1 weapons in the battle royale. The update also synchronizes progression across Multiplayer, DMZ, and Warzone. This shared progression features a player level reset. Furthermore, players will share progress across Daily Challenges, Calling Card Challenges, Apex Attachments, the Battle Pass, and Black Cell.
Moreover, Season 1 introduces several new maps across the entire game ecosystem.
| Game Mode | Map Additions & Details |
| Multiplayer (Launch) | Canyon Shoot House Backstab |
| Multiplayer (Mid-Season) | 3 Additional Maps |
| DMZ | XO1 (Smaller, intense map with unique loot and orders) |
| Warzone (Launch) | Hajin (New Map) Zodiac (Resurgence Map) |
| Warzone (Mid-Season) | Verdansk Rebirth Island |
