Newly revealed court documents from an ongoing antitrust lawsuit claim that Valve once threatened to remove Rainbow Six Siege from Steam after Ubisoft tried selling the game at a lower price on its own storefront, Uplay.
According to the reports, Ubisoft introduced a cheaper “Starter Pack” version of Rainbow Six Siege outside of Steam.
Valve allegedly warned Ubisoft that the game could be removed from Steam if the pricing difference wasn’t addressed. Ubisoft changed course, and the game remained on the platform.
