Amazon has unveiled yet another add-on for its paying Prime subscribers, and it represents the company’s biggest tie-in yet with Twitch, the game-streaming service that Amazon acquired in 2014 for nearly $1 billion.

The new add-on, Twitch Prime, will dole out monthly gaming-related goodies to any Amazon Prime subscriber who links their shopping account with a Twitch user ID. Upon doing so, Twitch users will get a few Twitch-specific bonuses. The first is a series of free game downloads, which change every month and can range from full-game unlocks to DLC add-ons for games you already own (much like PlayStation Plus and Xbox Live Gold). Twitch Prime’s first month includes a full download of the Twitch-enabled multiplayer game Streamline and add-on bonuses for free-to-play games Hearthstone and Smite.

Twitch Prime appears to be enabled for Prime subscribers in the US, UK, Spain, Germany, France, Canada, and Italy.
