EngineOwning charges 13 euros per month or more for subscription access to individualized suites of cheating tools designed for Call of Duty games -- and also Battlefield, Titanfall 2, and Star Wars Battlefront. The software promises abilities like automated aimbots, auto-firing triggerbots, "2D radar" that shows enemy locations on the HUD, and "3D radar" that can track and display opposing players even behind cover.

EO promises its software is undetectable by automated tools, including Activision's recently launched Ricochet kernel-level anti-cheat tools.

The software also includes built-in tools to make cheating less obvious to human moderators and recording software, making users "look like a legit player."

The company separately sells "hardware ID spoofer" software that promises to get around hardware-based bans in Call of Duty and other games.

In its lawsuit, Activision says these tools have been used "thousands of times by players in the United States," earning EngineOwning "hundreds of thousands of dollars or more." Thus, the software has led to "at least tens of thousands of breaches" of the terms of use players must agree to before playing online.
