Call Of Duty: Warzone And Modern Warfare Season 4 Update Patch Notes

Following a delay, Activision has released the much-anticipated Season 4 update for Call of Duty: Modern Warfare and Warzone on PS4, Xbox One, and PC. Infinity Ward also released the full patch notes, and there were many changes introduced to the two games with the update. Read on for a look at the notes and a rundown on what's new and different.

Bug fixes also arrived June 13, including a fix for spawning outside of the Scrapyard map, as well as a fix for people unable to use content unlocked in the Battle Pass. It also fixed the frequency of in-game events in matches.

The file size for the patch has also been announced, and it is gigantic. However, once the update is installed, the game will only take up an additional 4 GB of space due to how it compresses the files. [Update: Some players found that the update is even bigger than expected on Xbox One, but it appears that was only due to a bug.]

Perhaps the biggest and most exciting part of the Season 4 update are the new multiplayer maps--Trench, Scrapyard, and Barakett Promenade. There's also a new battle pass that spans both Modern Warfare and Warzone, and MW has new modes and missions to go along with the maps.

Additionally, some big changes have arrived in the Warzone mode. Infinity Ward has introduced in-match events, and these can occur at any point without notice.

The first of the modes is called Jailbreak, and it sets free everyone who was waiting in the Gulag and everyone who was still spectating. "You will 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," Infinity Ward said.

The second new in-match event is called Fire Sale. Like its name suggests, this discounts every item in the Buy Station by 80 percent, or gives them away completely free. The Fire Sales only run for 1 minute, so players will likely rush to the Buy Stations, creating a deadly showdown between squads.

Finally, the Supply Choppers event adds a "non-lethal but heavily armored" helicopter to the map. This helicopter has lots of health, so you need to shoot it with a rocket or a lot of weapon ammo to take it down. When the helicopter is destroyed, it will drop "high quality loot," including three UAVS, two armor boxes and munitions boxes, a gas mask, a grenade launcher, and lots of Cash.

"Supply Choppers leave after a certain period of time, so if you want to take one out start firing right away. Remember, that 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," Infinity Ward said.
