The Xbox Game Pass library on Xbox One expands today with seven more games, including Metal Gear Solid V: The Phantom Pain, Halo Wars Definitive Edition, and Resident Evil HD. The four others are Oddworld: New 'n' Tasty, The World of Van Helsing: Deathtrap, Mega Man 9, and Sky Force Anniversary. All of these games were added today, November 1.

One important note is that The Phantom Pain is in the Xbox Game Pass catalog only until January 31, 2018, while the six others are slated to be there indefinitely. Microsoft has been up front from the start that not every game will stay in the catalog forever, but that you can subscribe with confidence knowing there will be a substantial library. In the case of The Phantom Pain, it's good that Microsoft is letting players know it won't be an Xbox Game Pass title forever.
