Just Cause 4, the open-world sandbox game from Avalanche Studios, is now available in the Xbox Game Pass free game library. WindowsCentral discovered that the game is now available in the Xbox Game Pass library, following a teaser that the Xbox Game Pass account tweeted.
In a silly, fake email purporting to be from "Melissa McGamepass," it's revealed that a game starting with a "J" would come to Xbox Game Pass on March 7. As it turns out, that game is (likely) Just Cause 4, and it's arrived a day early. The email image also says another game with a longer title is also coming to Xbox Game Pass on March 7, but it hasn't been revealed yet.
Further out, Microsoft will announce another title coming to Xbox Game Pass in April later this month on March 12. Keep checking back with GameSpot for more on that.
Given that Just Cause 4 was only released commercially in December, it appears to be one of the newest titles in the Xbox Game Pass library apart from the first-party Microsoft games that release into Game Pass like Crackdown 3 most recently.
In February, Microsoft released a number of high-profile titles into the Xbox Game Pass library including Batman: Return to Arkham, Shadow of the Tomb Raider, and Alien Isolation.
Xbox Game Pass offers all-you-can-play model where you can play more than 100 Xbox One and backwards-compatible Xbox 360 games as much as you for as long as your $10/month subscription remains active. Outside of this, Microsoft also offers Games with Gold for Xbox Live Gold subscribers, which grant a few games every month.
