Epic Games and Match Group are looking to fortify their antitrust lawsuits against Google by adding new counts to their initial complaint, filed last year, which illustrate the lengths Google supposedly went to in order to dominate the Android app market. The companies on Friday filed a motion to amend their complaints in their cases against Google, which now allege that Google paid off business rivals not to start other app stores that would put them in competition with Google Play. This would be a direct violation of U.S. antitrust law known as the Sherman Act, the amended complaint states.

Epic Games and Match Group had originally detailed Google's plans in a filing last year, where they detailed a Google program known as "Project Hug," or later, the "Apps and Games Velocity Program." This effort was focused on paying game developers hundreds of millions of dollars in incentives to keep their games on the Google Play Store, it had said.

The program itself had arrived following Epic Games' release of Fortnite outside Google Play in 2018, where it bypassed Google's marketplace fees. (The game later returned to Google Play in April 2020 until being removed for allowing users to bypass Google's fees when making in-app purchases.) Google, at the time, had been concerned that Epic may choose to partner with an OEM like Samsung for a preinstall deal. It also worried that other companies might follow Epic's lead, leading a new wave of alternative Android app stores.

The project had been said to involve helping the developers with additional promotions, resources and investments, and was deemed a success as Google signed deals with many of Project Hug's targets, including Activision Blizzard.

Now, Epic Games and Match Group are looking to add to their complaint with two new allegations specifying how Google had either paid or otherwise induced its potential competitors to agree to not distribute apps on Android in competition with the Play Store, including through their own competing app stores. Google, it says, had identified developers who were "most at risk … of attrition from Play" and then approached them with an offer of an agreement.
