Three screenshots for the upcoming Poker Night at the Inventory 2 have been leaked. I’m not totally sure where these have leaked from (having discovered them reuploaded elsewhere), but it looks like they were originally on Microsoft’s Xbox servers under a database listing for the game.
Although the game has not been formally announced, it has been assumed that the current Key Party promotional website was leading up to it being unveiled.
As you can see from the screenshots below, the game is indeed another poker party. Our beloved Sam joins a cast of characters such as Claptrap (from the Borderlands games), Brock (from Adult Swim cartoon Venture Brothers) and GLaDOS (from the Portal games).
Keep your eyes on the site for further details like platform (although assume PC and Xbox for now, at least) and release date.
