MODES

Battle Royale

Core
Best in-class. Drop into Al Mazrah to experience all of the new features in Warzone 2.0.

Third Person
For the first time in Warzone history, players can now play with the camera fixed behind their Operator model and have the ability to swap between the left and right shoulder when aiming. Players will have to entirely rethink how they approach movement, engagements, and their overall strategy.

Unhinged
Break the squad limit boundaries by using Assimilation to grow your squad up to 6 players! Alliances are fragile in this game mode and you may find yourself out numbered at any point.

DMZ

Trios
- Max Players: 66
- Assimilation Setting: Up to 6 Players Per Squad
- Solos or Duos can elect not to fill

We are excited to debut DMZ with the launch of Warzone 2.0. DMZ is a dangerous, diverse and deep open world experience where players can choose their level of intensity.

Borrowing from the full blog we posted last week, here are a few critical pieces of information ahead of your first infil to the Al Mazrah Exclusion Zone:

In DMZ, the conditions for winning are your own– you decide the stakes.

- Players choose missions from three factions which level-up as you complete objectives. Each mission has a unique reward and missions get progressively harder.
- Squads can pick up contracts in-world for extra cash and XP.
- The many locked spaces in Al Mazrah can be opened with specific keys found around the map.
- If you’ve had your fill and want an even harder challenge you can go after other operators and harvest whatever they have looted.
- Exfil is always the ultimate goal.

When gearing up players can choose between their Insured Weapons which are built from Gunsmith progression unlocks or from their Stash of Contraband Weapons. If an insured weapon is lost in the DMZ it goes on a cooldown. Players can wait for this cooldown or they can extract cash to speed up the time it takes to get their insured weapon back. Contraband weapons are weapons extracted from the DMZ. These cannot be changed and if they are lost, they are lost for good.

We look forward to players diving into the DMZ. We’re excited to see our community map out the many locked areas and we can’t wait to see all of your battles over the Weapons Case. Al Mazrah is a dangerous place… Our recommendation to all of you: conserve your ammo, stay with your squad and watch your six. Good hunting.

New Gulag

This abandoned medieval fortress off the coast of Al Mazrah has been repurposed for sinister games by Shadow Company.

GAMEPLAY

Feature Highlights

New Strongholds & Black Sites
Strongholds are a brand new, multifaceted feature that are going to fundamentally change the way some players choose to spend their time. They represent a high-risk opportunity for teams to get a full Loadout early and a localized UAV for strategic positioning. Teams that are the first to clear a Stronghold will be granted a single Black Site key - an invitation to challenge fortified enemy combatants for the most valuable loot Al Mazrah has to offer. Black Sites are only found in Battle Royale.

New Gulag Experience
This new 2v2 Gulag offers different pathways to ensure redeployment including an unprecedented co-optional one. Duos can choose to eliminate the enemy squad to secure release before overtime. Players will spawn with a Pistol or Shotgun, one Lethal Equipment, and one Tactical Equipment. Superior ground loot will spawn towards the center of the map, getting progressively more valuable over match time. Once Overtime kicks in, The Jailer will spawn. Players will have the choice to work together to eliminate this foe, rewarding all 4 Players with redeployment to the battlefield. Ultimately, however you choose to win, you’ll redeploy with everything you looted for another chance at victory.

New Multi-Circles
At random, and at any point during a Battle Royale match, the circle can split into upwards of 3 smaller circles, which will ultimately remerge for the final showdown. With mobility being a crucial factor here, we’ve put an emphasis on player choice as far as vehicles go and whether your team travels by air, land, or sea.

New Loadout System

Custom Loadouts

Custom Loadouts can be built in the Gunsmith menu and are composed of a Primary Weapon, a Secondary Weapon, a choice of Lethal Equipment, a choice of a Tactical Equipment, and a choice of a Perk Package designed around preferred playstyles.

Buy Stations
The Primary Weapon that players design for their Loadout will be available to purchase via Buy Stations found throughout Al Mazrah.

Stronghold Crates New Landmark Rewards
In Battle Royale, if players want to access the entirety of their Loadout early, they’re going to have to work for it. Full Loadouts can be earned as a reward for completing one of the three active, AI-defended Strongholds found throughout the map.

Loadout Drops
Not willing to brave an early Stronghold? A new mid-game Public Event will drop a limited number of Loadout Drops for players to claim. It’s worth noting that an individual Loadout is only usable once per player on a team, but will remain on the field for other teams to loot.

New Looting System
- Players will have access to the new Backpack & Inventory system, uniquely adapted to Battle Royale and DMZ modes, which allows for a more strategic approach to looting.
- In Battle Royale, loot will pop out of Supply Boxes onto the ground, allowing players within close proximity to automatically pick it up. This will either stack with existing slots or fill new ones.
- In DMZ, players will be presented with the entirety of the new Backpack, having to carefully choose when to loot and how to manage their inventory.
- Loot containers can come in different shapes and sizes, including but not limited to: duffel bags, cash registers, weapon lockers, and medicine cabinets.
- Player opponents will also drop a lootable Backpack upon elimination that uses this system.

And So Much More…

Warzone 2.0 was built from the ground up with Modern Warfare II as a shared experience.The key innovations we’ve brought to MWII Multiplayer exist across Warzone 2.0 as well.

Below we will discuss new features from Modern Warfare II, alongside familiar features from the original Warzone, that we’ve brought together into a single, ultimate Battle Royale experience.

Squad Score in the UI
Players will now be able to see the total scores for their entire squad in the in-game Scoreboard.

Players who are parachuting can now mantle and ledge hang.
