Season 4 is live in Call of Duty: Warzone 2, and the big update puts some restrictions on DMZ's bartering system that was introduced in Season 3. Here we walk you through the best recipes in Season 4, and we explain how to unlock the restricted barter recipes in the Buy Station.

DMZ's barter system isn't player-to-player trading, but more of a way to swap scavenged items at a Buy Station to trade for something else you need. This bartering is done using recipes, which are component lists needed to receive the new items.

These recipes are found at the Buy Stations around the maps, and they are set lists that can be memorized for easy bartering. Most recipes will be common across all maps, but Building 21 and Ashika Island locations each have a few of their own unique sets of barter options across its Buy Stations, but we'll highlight the important ones here.

Additionally, Season 4 now restricts some of the high-end items that were previously available in Season 3. The recipes didn't change from last season, but even if you have the components needed to trade, some items are locked as restricted items in the Buy Station.

You'll quickly realize several barter items are locked in the Buy Station. The ability to barter for these restricted items must be unlocked in the Bounty Board section of DMZ's new Upgrades menu by reaching reputation level two of the White Lotus faction. Faction reputation is the new way to level up in DMZ for Season 4, and we have a full guide on how to level up faction reputation.

The following items below are locked in the Buy Station:

The 3-Plate stealth carrier, which in addition to holding three armor plates, comes built-in with the Ghost perk to help keep you off enemy radar. If you're looking to go under the radar in your match, you'll need to scavenge these items:

The medic vest lets you get armored up while also granting both faster revives on squadmates, as well as faster self-revives when using a self-revive kit. To suit up as a medic, you'll want to scavenge these items:

This is a special key that can unlock any door in DMZ, with the only exception being entry to Building 21. You'll still need to get a Building 21 Access Keycard to access that location, but you can use the skeleton key to unlock spaces within Building 21. The only way to get this key is to craft it with these items:

The GPU is a bit rarer than some of the other recipe requirements, but is found at random when searching the various computers all over the map. It also has a recipe of its own.

You can barter for a GPU to make getting a skeleton key or completing a specific mission a bit faster. So far, this seems specific to Ashika Island, so you'll want to visit the island and scavenge these items:

The secure backpack lets you secure scavenged items between runs, meaning the valuables you loot like GPUs and hard drives will stay in your pack for the next match, instead of converting into XP. You also won't lose these items if you die. This only includes "non-Contraband, non-on-soldier items" in your inventory, so it won't include Contraband weapons, killstreaks, gas masks or self-revives. You'll want scavenge these items:

The scavenger backpack provides more inventory slots. To have the best backpack for a scavenging session, you'll first want to loot these items:

The comms vest lets you get armored up and provide valuable intel. This vest is like a signal booster. It increases the duration of all UAV technology in DMZ (the killstreak, UAV towers, and enemy radios dropped by AI) and makes them function as Advanced UAVs, meaning they also show player direction and location.

The new tempered plate carrier is an armored vest, which works just like Warzone 1's tempered plate carrier. Your armor will be two half-bars instead of three thirds, making it easier and more efficient to re-plate after a fight. So far, this vest seems specific to Ashika Island, so you'll want to visit the island and scavenge these items:

The Revive Pistol field upgrade is a great option to take into a match of DMZ, especially if you're the medic of your team. You'll need to scavenge these items:

Durable gas masks are always handy for either venturing into the radiation zone or trying to make a last minute escape to an exfil location. You'll need to scavenge these items:

If you're looking to go for a swim around any of the maps, or complete the objectives needed to unlock DMZ's exclusive Heated Madness weapon blueprint, you likely want to barter for rebreathers for you and any teammates. You can find them at random while scavenging, but they can be a bit rare to find sometimes. You'll need to scavenge these items:

You can never have enough armor in DMZ, especially with all the AI enemies trying to chip away at your armor plates. You'll need to scavenge these items:

These recipes should help you get some of the best gear in the game, and hopefully help you survive your next match of DMZ. If you're looking for high-tier places to loot for gold bars, skulls, and other items, make sure to check out our guide for best loot locations for DMZ.

If you still need to unlock additional insured weapon slots, Season 4 makes it so much easier to level up in each faction. Here's everything you need to know about the new faction reputation system, and here's how you can unlock insured weapon slots and cooldown bonuses.
