Beat-em-ups, adventure games, and more now playable on Xbox One
The list of backward-compatible games on Xbox One grows pretty substantially today, with five new Xbox 360 games being added.

As revealed by Microsoft's Major Nelson on Twitter, it's an Xbox Live Arcade-heavy selection of games without any particularly big names. Here's the full list:

Altered Beast
The Cave
Comix Zone
Double Dragon: Neon
Ghostbusters: Sanctum of Slime

If you already own (or decide to buy) any of these games, they'll show up in the Ready to Download area of the My Games and Apps section on your Xbox One. You can download and play them like any other game.
