DMZ Season 4 patch notes: Upgrade system, Vondel map, progress reset

Infinity Ward has continually supported DMZ throughout Modern Warfare 2’s life cycle with new features and maps, and that promising trend continues in Season 4.

Call of Duty’s extraction shooter game mode is still in Beta and has undergone massive changes. Over just three seasons of content, the devs have already released several new environments and game-changing features.

This includes Season 3, which introduced fundamental changes. The Barter system added a way for players to swap items they collected for other valuables. DMZ’s new workbench feature allows users to either add or remove an attachment to contraband weapons.

Season 4 is no different, providing the passionate fan base with the mode’s second-ever progress wipe and a streamlined method of completing missions. Let’s jump right into everything you need to know.

Forward Operating base introduced to DMZ in Season 4

Activision

Infinity Ward described the Forward Operating Base (FOB) as the “central hub” for DMZ. Faction missions are still in the game and need to be equipped as before, but FOB lets players unlock upgrades passively.

FOB features unlocks such as insured weapon slots, barter recipes, buy station discounts, and more. The new system is also how players will obtain new features that are coming to the mode in Season 4.

The developers argued that this change will make it easier for players to complete challenges without needing to select a mission before deploying.

New DMZ map Vondel

Season 4 introduces Vondel to Warzone’s map rotation and also opens its doors to DMZ players. The urban map is set in the Netherlands and features 18 operators or six squads per match.

Squads will be able to complete a DMZ contract exclusive to the map that tasks players with hacking phones. Similar to the sandstorms on Al Mazrah, Vondel introduces a fog system that impacts visibility in matches.

Season 4 progress reset

Faction Mission progress, contraband, key, and mission inventories also undergo a reset in Season 4. The wipe will not affect earned rewards such as blueprints, skins, and calling cards.

However, One big difference from the Season 2 wipe is a reset of insured weapon slots. Players will need to re-unlock their insured weapon slots by coming Forward Operating Base objectives.
