The Modern Warfare 2 Season 1 Reloaded mid-season update is here and thanks to Infinity Ward, we have the patch notes and new content including Raids and the return of Shipment to share.

Modern Warfare 2 has smashed records and given players a brand-new campaign and multiplayer to enjoy. That said, as we enter the game’s first midseason update, along with Warzone 2, many are looking forward to the content that awaits.

The first season has been a successful one so far, despite the odd dip in its player count, and the Modern Warfare 2 Season 1 Reloaded update delivered a new map, new gun, and new game modes.

Here’s everything you need to know about Modern Warfare 2 Season 1 Reloaded including the return of Shipment, Raids, and patch notes.

Modern Warfare 2 Season 1 Reloaded start date

Modern Warfare 2’s Season 1 Reloaded update went on December 14, which is roughly halfway through the game’s first season.

Alongside new content for Modern Warfare 2, Season 1 Reloaded also brings Warzone 2’s “first post-launch update,” ironing out any major bugs and glitches ahead of the holidays.

Shipment arrives in Modern Warfare 2 Season 1 Reloaded

Infinity Ward revealed that the two new maps for Modern Warfare 2 Season 1 were Shoot House and Shipment. While Shoot House arrived with the Season 1 launch, Shipment arrived with the mid-season Reloaded update.

The devs also revealed that “Holiday Shipment” will arrive on December 21 until January 4 to celebrate the Christmas Holiday.

Despite being a classic map, it does seem that the community is somewhat fed up with seeing this map be remade every year, even if it means they can get their camo challenges done quicker.

Many are hoping for classic maps such as Highrise or Terminal for later seasons, as these appear in Warzone’s Al Mazrah map, but there’s no guarantee yet. That being said, Season 2 content has already leaked and it’s more disappointment with another recent map remake potentially on the way.

New weapon & Operators for Modern Warfare 2 Season 1 Reloaded

The Chimera Assault Rifle arrived in Modern Warfare 2 Season 1 Reloaded for multiplayer and Warzone. This new weapon is in the Bruen Ops Platform, which is the same as launch weapons like the M13B and BAS-P.

As well as a new AR, players will also be able to get their hands on new Operators in the mid-season update, Klaus and Gaz. Most players will be familiar with Gaz from the Campaign, but Klaus is “a member of Denmark’s Elite Special Forces.”

Gaz can be unlocked by completing the new Raid mission arriving in the Season 1 Reloaded update, as well as in a Store Bundle. Klaus can be unlocked by purchasing the Klaus Operator Bundle in the Store.

Modern Warfare 2 Season 1 Reloaded brings Raids

Players will finally be able to experience Raids in Modern Warfare 2, as this new co-op PvE mode dropped alongside the Season 1 Reloaded update.

Thanks to a reveal at The Game Awards, we know that the first Raid will be called Atomgrad, and the Call of Duty blog has revealed that it will see “Price, Farah and Gaz make a grim discovery in an underground bunker.”

This will continue on from the events of the MW2 Campaign, and those who complete it will “unlock a familiar face as a brand-new Operator to use in Multiplayer and Special Ops, as well as in Warzone 2.0,” and “a harder difficulty Playlist that will test even veteran Operators.”

Players will need a Raid Key to access the Raid, which can be earned by the following:

  • Complete a specific Daily Challenge either in Multiplayer or Special Ops.
  • Place within the top 20 in any Warzone 2.0 Battle Royale Playlist.
  • In DMZ, use the final extract helicopter with at least $30,000 in Cash.

After gaining a Raid Key, you and the selected two other teammates can access the Raid for a full week.

New Modern Warfare 2 Social Feature: Groups

Modern Warfare 2 Season 1 Reloaded also brings a new social feature known as Groups. This is accessible through the Social menu and will allow players to create communities with other Call of Duty players.

A Group can have up to 5,000 members, and preferences such as New Player Friendly and Veterans Only can be selected to filter members.

Call of Duty’s first ever RAID is here in Atomgrad Episode 1. Raid Episodes will be released seasonally and will be an exciting mix of combat and puzzles for 3-person teams to explore.

Over the course of 5 seasons, a new narrative will unfold, beginning where we left off at the end of the Modern Warfare II Campaign. Expect new storylines and old friends.

In order to access the Raid, you must obtain a Raid Assignment, which can be unlocked by completing one of the following:

–       Complete a specific Daily Challenge either in Multiplayer or Special Ops.

–       Place within the top 20 in any Warzone 2.0 Battle Royale Playlist.

–       In DMZ, use the final exfil helicopter with at least $30,000 in Cash.

Once obtained, a Raid Assignment will last for one week. Only one player needs to have an active Raid Assignment in order to access the Raid. However, there is no matchmaking– it’s up to you to build your team.

Raid drops are randomized and completing the Raid multiple times will unlock different rewards, including Veteran mode.
