With the sea of games released on Steam every day, it’s difficult to know which ones are included with the Game Pass subscription. To solve this problem, the solution comes from a user who developed a Chrome extension. This tells you whether the Steam game you’re watching is included or coming to Microsoft’s service soon. It also shows the platforms the game is running on.
Installing third-party extensions is of course everyone’s responsibility. The developer has also indicated that it will eventually be open source. Only available on Chrome, he intends to bring it to other browsers like Firefox very soon.
