Activision and Infinity Ward have finally released the Season 4 update for Modern Warfare on PC, Xbox One, and PS4, introducing two new weapons, three maps and a brand-new Battle Pass for players to sink their teeth into.

There’s been a lot of anticipation for Modern Warfare Season 4, especially after the seasonal update was delayed by a week, but on Thursday, June 11, fans of the legendary FPS series finally got their hands on the new season, and it comes stacked with new items and challenges.


As always, new guns are the biggest additions to this update, with a new SMG and a fresh Assault Rifle both introduced, giving you two new options in combat whether you’re playing the game’s multiplayer mode, or searching for victories in Verdansk while playing Warzone.

What’s new in Season 4?

New maps: Scrapyard, Trench, Barakett Promenade

Of the new maps introduced at the beginning of the season, some will feel familiar to hardcore players. Modern Warfare 2’s Scrapyard is returning as a proper multiplayer map after being featured in Warzone, and teased in the original Season 4 announcement trailer. This comes with its own 24/7 playlist at launch as well.


Trench is a new 2v2 map for close quarters modes. Expect to see this one quite frequently over the next few weeks if you’re a Gunfight fiend.

Lastly, a new Ground War map has been added into the mix. Barakett Promenade may ring a few bells, as this is a Warzone location found in Verdansk already. Plays can now jump into matches on this map with their squad, and battle against their opponents.

New weapons: Fennec & CR-56 Amax

After numerous leaks hinted that players would be seeing the return of weapons from Call of Duty: Ghosts, Infinity Ward confirmed those suspicions by introducing the Fennec SMG which is an updated version of the Vector, and the CR-56 Amax which is a reworked Galil.


As always, both the Fennec and CR-56 Amax are available as part of the free portion of the Season 4 Battle Pass, with early reports claiming that the SMG is already extremely powerful and could become the go-to weapon for aggressive players. You can watch the Fennec in action below.

Battle Pass and Captain Price Operator

Speaking of the Battle Pass, Infinity Ward have added the Season 4 iteration of the content pass, featuring 100+ tiers of rewards that players can unlock by grinding the game. As usual, the pass has both a free and Premium section, the latter costing 1,000 CoD Points (~$10 USD).

One of those rewards will be Captain Price, the legendary character from the Modern Warfare series, including the 2019 campaign, along with special horns for your vehicles in Warzone, and a ton of Weapon Blueprints and cosmetic items too.

Warzone In-Match Events

The latest addition to Warzone coming in Season 4 is “In-Match Events,” which will change the way the battle royale is played at random times “without advance notice” throughout any given match. There are three In-Game Events being added: Jailbreak, Fire Sale, and Supply Choppers.

When ‘Jailbreak’ occurs, all eliminated players who are either waiting for their chance to be respawned from the Gulag, or are spectating their teammates, will be given a one-minute notice before being returned to the battlefield. This event can occur at any time mid-game, so it’s “well worth spectating, just in case,” according to Infinity Ward.


The second in-game event, ‘Fire Sale,’ works in a similar fashion to the popular Call of Duty Zombies power-up. When activated, this event gives all Buy Stations a temporary discount, with items selling for anywhere up to 80% off. Some items may even be free. Loadout Drops are not discounted during Fire Sales. This in-game event lasts for 60 seconds.

The final new event is ‘Supply Choppers,’ which brings “non-lethal but heavily armored helicopters to Verdansk.” These helicopters will not shoot at you, but you can destroy them to grab a stack of “high-quality loot.” This includes three UAVs, two armor boxes and munitions boxes, a gas mask, a grenade launcher, and tons of cash at a minimum.
