Modern Warfare 2's mid-season "Reloaded" update for Season 1 is now live, and the big update added Call of Duty's first-ever Destiny-style Raid. Unfortunately, you can't jump in right away, as there are some prerequisites to consider. Here is everything you need to know to play Episode One: Atomgrad.

What are Raids in Modern Warfare 2?

Raids continue the story of Modern Warfare 2's campaign, and this is a trio mode with a mix of stealth, action, and puzzle-solving objectives. Episode One: Atomgrad launched on December 14 with Season 1 Reloaded, and Infinity Ward confirmed a new Raid episode would be added for each future season of Modern Warfare 2, confirming the game would have five seasons total.

How to access the Raid

Call of Duty's Raid is not included in the free-to-play Warzone 2 application, and you'll need to have purchased Modern Warfare 2 to play. Additionally, you will need to earn a Raid Assignment, which is the credential needed to actually play the Raid.
