Everything New in Call of Duty: Modern Warfare III - Season 3

ign.com:

Season 3's update hit Call of Duty: Modern Warfare 3 and Warzone today and there’s a lot of new content. There are new game modes, the return of Rebirth Island, new Perks, new weapons, and so much more! Here’s everything you need to know that’s new in Season 3.

Modern Warfare 3 dropped four new game modes in Multiplayer: Capture the Flag, One in the Chamber, Minefield, and Escort. CTF and One in the Chamber are available at launch with Minefield and Escort dropping mid-season. Minefield will be a variation available in Kill Confirmed, Domination, and Hardpoint.

In Minefield, dead players will drop a Proximity Mine that will be deadly only towards their own teammates. Escort is a pretty self-explanatory game mode where one team has to escort a MAW across a map while the other defends and tries to stop the attackers. The match will include a side swap after the first game and the team who delivers the payload the fastest, wins.

There are six new Core 6v6 maps in Season 3 with four available immediately: 6 Star, Emergency, Growhouse, Tanked. The other two maps, Checkpoint and Grime, will be coming later in the mid-season update. These last two maps are adapted from Warzone POIs and have been adjusted for smaller 6v6 play.

Season 3 brings in three new Perk Vests, a new pair of Boots, and new Gear. One of the new Gear items is a High-Gain Antenna which zooms out your minimap for you and nearby allies and enemies remain on the radar longer for you. It also allows you to see nearby ally radar pings from their equipment.

The other new Gear item is a new Tactical called the EMD Mine coming later in the midseason refresh. It’s a proximity mine that shoots out trackers that stick to enemies and reveals them until the tracker is removed.

The Gunslinger Vest makes you a Secondary Weapon specialist with no Primary Weapon slot and only two Secondary Weapons for your loadout. This Perk Vest refreshes stamina on kill, improves reload speed, reload while sprinting, increases weapon swap
