Full Patch Notes

What's New?

Weapon Mastery Challenges

After you have unlocked Gold camouflage for a weapon, new Mastery challenges will be available for players to complete. There are a total of eight challenges for each weapon in the game, each containing their own rewards. There are a total of 4 new Playercards and 4 Emblems to earn.

There are two Kill Challenges, two Headshot Challenges and four additional challenges that must be done in a particular order (Gold, Damascus, Obsidian) If players complete all 51 challenges, they will receive a unique sticker and Playercard.

Warzone In-Match Events

Events can take place during a Warzone match and can have a huge impact on strategy. Only one type of event will take place in a match so it's going to be important to familiarise yourself with each of the three event types that have been added for Season 4.

  • Jailbreak - When this occurs, all eliminated players will be released back into the game. There will be a one-minute notice before the event happens to find extra armor or a weapon for teammates dropping back into Verdansk. A jailbreak can take place at any time during the middle of a Warzone game.
  • Fire Sale - This in-game event temporarily discounts the majority of items available at the Buy Station up to 80%, making it the perfect time to get your hands on killstreaks, self revive and more. During a Fire Sale, bringing back a teammate is totally free so if your team is short on cash, the Fire Sale can bring you right back into the game. Be warned! Fire Sales only last for 60 seconds so expect Buy Stations to be crowded.
  • Supply Chopper - This event brings a heavily armoured helicopter into the game. Armed with a lot of health, this non-lethal chopper will require a lot of ammunition to deal with. Once destroyed, it will drop plenty of high quality loot including three UAVs, two Armor Boxes and Munitions Boxes, gas masks, grenade launchers and a load of Cash. Watch out for any enemies looking to steal the loot after your team has done all the hard work!

Contraband Contract

Contraband is a brand-new contract which will unlock a new Blueprint once completed. The new contracts have the potential to spawn after a previous contract has been completed. If you secure the briefcase, grab it and take it to the extraction location to call in the chopper. The player carrying the case must deposit it into the drop-bag to complete the contract. If a player kills the briefcase carrier, they can take it and complete it for their team.

Playlist Update

  • Barakett Promenade has been added to Ground War!
  • Trench Mosh Pit (2v2)!
  • Scrapyard 24/7! 
  • Blueprint Gunfight!


  • Quads
  • Trios
  • Duos
  • Solos
  • Blood Money
  • Warzone Rumble!

Warzone Rumble is a brand-new mode in Warzone. Two teams of 50 players parachute and battle it out in various areas around Verdansk. This mode is high action with custom loadouts, vehicles, and quick respawns.
