It's a new month, and that means another set of games for Xbox Game Pass, Microsoft's all-you-can-eat subscription service for games on Xbox One. The $10 per month service offers unlimited downloads of its library, which promises all first-party Xbox games on the day of release. This month the spate of games includes contract killing, cyberpunk shooting, and zombie slaughtering, just to name a few. [Update: Alongside all of these, you can also get a just-released game, Graveyard Keeper, for free with Game Pass.]

As of August 1, Game Pass includes the entire first season of Hitman, the episodic reboot of the classic series. Its sequel, Hitman 2--which abandons the subscription model--is launching this November. Ruiner is an action shooter set in a cyberpunk dystopia, and Ryse: Son of Rome was a much-talked-about Xbox One launch game renowned for its visual feats. The Escapists: Walking Dead takes the adorable pixel art and gameplay of The Escapists series and applies it to the zombie franchise. Dandara is a metroidvania with some fluid gravity-defying reversal.
