Modern Warfare 2 introduced its inaugural Raid experience on December 14, marking a significant evolution in Call of Duty’s cooperative gameplay. This comprehensive guide delivers proven strategies to conquer this challenging new mode.
The Season 1 Reloaded update brought Destiny-inspired Raid mechanics to Modern Warfare 2, creating a demanding three-player experience that emphasizes strategic puzzle resolution, tight team coordination, and constant communication. Our detailed walkthrough provides the essential knowledge to successfully complete the mission and secure all available rewards.
Raids extend Modern Warfare 2’s narrative arc from the campaign, presenting a specialized trio mode blending stealth infiltration, intense combat encounters, and complex puzzle objectives. This combination closely mirrors the intricate Easter egg challenges found in Call of Duty’s Zombies mode. Episode One: Atomgrad debuted alongside Season 1 Reloaded, serving as the first installment in a planned series of five seasonal episodes, with additional Raid content scheduled for each subsequent Modern Warfare 2 season.
To unlock Raid access, players must first accomplish specific in-game challenges to obtain Raid Assignments. For detailed instructions on accessing Atomgrad, consult our dedicated access guide.

Once your team is assembled and prepared, here is the complete strategic breakdown for conquering the Atomgrad Raid efficiently.
Begin by eliminating all hostile forces in the starting area, then navigate along the water pathway toward the facility’s rear right section. Look for a distinctive room marked by a crimson light above its entrance. Enter this chamber to discover a central table arrangement featuring four monitor displays. Activating the scarlet button positioned on the wall to the right of these screens reveals an adjacent room with an identical four-monitor configuration. The initial chamber serves as your primary operations room, but solving the encryption challenge demands coordinated use of both spaces.

Effective team organization is crucial for this segment. Divide your three-player squad into specialized roles: assign two operators to monitor duty—one in each room—while designating the third member as the dedicated code interpreter.
The code-reading specialist operates from the main chamber, positioned at the decryption terminal located in the corner left of the monitor array. This interface displays three-character sequences composed of blended American and Russian alphanumeric symbols.

For experienced squads seeking to optimize their Raid performance, implement these advanced techniques. Designate specific callout protocols for character identification to minimize confusion between American and Russian symbols. Establish clear communication channels between monitor operators and the code reader to prevent transmission errors.
Common mistakes include rushing the initial combat phase without proper area clearance, which can lead to ambushes during puzzle solving. Teams often fail to properly coordinate between the two monitor rooms, resulting in mismatched inputs. Advanced players should pre-assign roles based on individual strengths—designate players with strong pattern recognition as code readers and those with quick reaction times as security.
Optimal loadouts should balance long-range engagement capability with close-quarters effectiveness. Consider equipping suppressors during stealth segments to maintain tactical advantage. The entire Raid typically requires 45-60 minutes for first-time completion, with experienced teams achieving sub-30-minute clears.
The cipher mechanics require understanding that each monitor displays complementary information—the secondary room provides verification and correction data for the primary room’s inputs. This dual-room verification system prevents brute-force solutions and ensures genuine team coordination.
Action Checklist
- Complete access challenges to obtain Raid Assignment
- Assemble three-player team and assign specialized roles
- Clear initial combat zone and navigate to red-lit room
- Solve cipher puzzle using dual-room coordination
- Coordinate code reading and monitor operation between team members
