Call of Duty: Modern Warfare Update Version 1.22: Season 4, Patch Notes, and More

The season four update for Call of Duty: Modern Warfare and Warzone is coming in just a couple of hours and the list of patch notes is extensive.

What’s new

Weapon Mastery Challenges

Once you’ve unlocked Gold for a weapon, Mastery Challenges become available. There’s eight challenges per weapon, each granting their own rewards, with four Playercards and four Emblems up for grabs. You’ll need to make your way through two Kill Challenges, two Headshot Challenges, and four additional challenges that must be done in order (Gold, Platinum, Damascus, Obsidian). Completing all challenges for 51 weapons unlocks a badass special Sticker and Playercard.

Warzone in-match events

Events can occur during Warzone Battle Royale matches and have an impact on the strategy and approach to gameplay. Events can happen in any given match without advance notice. When they happen, events will always occur mid-game. E.g. after the first drop kit and before the Gulag closes. Only one event type will occur in a given match, so familiarize yourself with three new event types, available at the start of season four: Jailbreak, Fire Sale, and Supply Chopper.

When a Jailbreak occurs, all players that have been eliminated will be released back into the match. Whether you were waiting for your one-vs-one in the Gulag or had been relegated to a spectator, now you’ll have another chance. You’ll get a one-minute notice before a Jailbreak event happens to find additional armor or secure a weapon for your returning teammates. Jailbreak events can occur any time during the middle game of a Battle Royale match, so it may be worth it to spectate, just in case. Be mindful that when a Jailbreak occurs, it’s not just your teammates that are coming back, but tons of additional enemies.

A Fire Sale is an in-game event that temporarily discounts most of the items at a Buy Station up to 80 percent or even gives items out completely free. A Fire Sale is a perfect time to pick up a UAV, Armor Box for your squad or even a lethal killstreak. During a Fire Sale, buying back a fallen teammate is completely free. If your short on in-match cash, a Fire Sale might be the best chance to redeploy a squadmate. Note that even during a Fire Sale, Loadout Drops aren’t discounted. Fire Sales only last 60 seconds, so expect Buy Stations to be crowded and prepare for a fight.

A Supply Choppers event brings a non-lethal, but heavily armored helicopter to Verdansk. The helicopter will have a lot of health, and it’ll require a few rounds of bullets and maybe a rocket or two to bring it down. The helicopter won’t shoot at you, but make sure that while you’re distracted enemy teams don’t take advantage. Once you destroy the Supply Chopper, it will drop high quality loot for players to pick up. This loot includes three UAVS, two armor boxes and munitions boxes, a gas mask, a grenade launcher, and tons of cash at a minimum. Supply Choppers leave after a certain period of time, so if you want to take one out, start firing right away. Remember, after taking down a Supply Chopper, you have to collect the loot. Watch out for enemy teams who might try to take you out during the collection or steal your hard-earned rewards.

Contraband contract System

Contraband is a new, rare contract with a permanent Blueprint Reward. Contraband contracts have a chance to spawn after a previous contract is completed. If you see the Contraband briefcase, hurry up and collect it. Once you have it, take it to the designated Helicopter Extraction location to call in the helicopter. The player carrying the briefcase must deposit it into the helicopter drop-bag to complete the mission. If you kill a player carrying this briefcase, you can steal it and complete the contract for your team. Be on the lookout for them on your Tac Map.

Download size

The season four download is going to be large. To reduce the overall disc space that MW and WZ take up, we’re compressing a bunch of assets. Once installed, the season four launch will only take up an additional four GB on consoles for all of the new content.

We’re continuing to sweep all assets to make size reductions where we can, and also further optimize future patches for size. If helpful, one reminder for console players, you can uninstall the content packs for modes that you’re not playing if you want to free up space.

You can learn how to do so here.
