Activision has revealed Call of Duty: Modern Warfare 2’s first Raid, which is titled Atomgrad. Continuing the story of Modern Warfare 2’s campaign, Raids are three-player cooperative challenges which mix stealth, combat and puzzle-solving objectives. The Atomgrad reveal trailer, which is viewable below, shows Price, Farah and Gaz swimming through a sewer system to infiltrate an underground facility. Raids will form part of Modern Warfare 2’s co-op Special Ops mode, which included three missions when the game was released in October. “We highly recommend completing all three Special Ops missions with three stars and have at least one Kit leveled up to Rank 5 before Raids, a direct continuation of the Campaign, are introduced to Special Ops later in Season 01,” Activision has said. The first “episode” of Raids will launch with the Season 1 Reloaded patch on December 14, which will also include a “legendary multiplayer map” and the first major Warzone 2.0 update. Details and artwork for Call of Duty Modern Warfare 2 and Warzone 2 Season 2 seemingly leaked this week.
