The Verge reports that Activision Publishing is suing Engineowning UG in California District Court, alleging the German company illegally sells cheat software for the Call of Duty series (thanks Kxmode). Due to the secretive nature of such businesses, part of the brief outlines why Activision believes several named individuals are involved in the business. The suit also names (or, technically, doesn't name) 50 anonymous "Does" as defendants. Activision accuses the company of harming fair play in a wide range of games over an extended period:

Via the EO Website and other related websites and social media accounts, EO and numerous affiliated individuals and resellers sell cheats for numerous COD Games, including without limitation Call of Duty: Warzone, Call of Duty: Modern Warfare (2019), Call of Duty World War II, Call of Duty: Modern Warfare III; Call of Duty Black Ops, Call of Duty Black Ops II, and Call of Duty Black Ops III (collectively, the “Cheating Software”). EO also claims to be developing new cheating software for the popular multiplayer game Overwatch, which is owned and published by Activision’s affiliate, Blizzard Entertainment, Inc. The Cheating Software enables players to manipulate the COD Games to their personal advantage, such as by automatically aiming weapons, revealing the locations of opponents, and allowing the player to see information that is not normally available to players because it would give them an unfair advantage within the game.
