Here’s a neat surprise for Xbox gamers: The cult classic game Phantom Dust is now available for free on both Xbox One and Windows 10.

“We put gamers at the center of everything we do and we are driven to build the best platform on which to create and play games,” Microsoft’s Adam Isgreen writes. “We’ve heard the feedback and passion from fans about this Xbox classic, and for this re-release on modern devices, we’ve decided to give it away for free. Yes, free.”

Better still, Phantom Dust for Xbox One and Windows 10 is an Xbox Play Anywhere title, so your game saves, achievements, and other advancements sync between the two platforms. You can even engage in cross-platform multiplayer.

Of course, you may be wondering what Phantom Dust is. According to Microsoft, this game launched in 2004 on the original Xbox in Japan, and it wasn’t originally released in the United States. (A different publisher did eventually bring the game to the US market.)

“Phantom Dust was hard to classify,” Isgreen explains. “A card game plus an action game with quirky Japanese style and a post-apocalyptic setting? Who’d ever heard of such a thing? Phantom Dust is an action-combat game for up to four combatants set in highly destructible arenas in which you choose from over 300 skills to build your arsenal of attacks, defenses, and special abilities. Draw odds and deck-building strategies collide with action combat, resulting in battles in which both wits and reflexes matter.”

Sounds pretty cool.

You can find Phantom Dust for Xbox One and Windows 10 in the Xbox Store.
