One of the biggest reveals at this year's E3 came from Microsoft when the company introduced Play Anywhere, a way to let Xbox One gamers play their games on Windows 10 PCs and vice versa.

What made this announcement so huge is that when an Xbox One gamer buys a copy of a game, that player also gets a copy of the same title for Windows 10. And it works in reverse, too.

"Now when you own an Xbox Play Anywhere digital title, it's yours to play on both Xbox One and Windows 10 PC," Microsoft writes on its website. "Buy once, play anywhere. Purchase an Xbox One Play Anywhere digital game, play it on both Xbox One and Windows 10 PC at no additional cost."

But that's not all: games compatible with Play Anywhere will also allow players to pick up gameplay wherever they have it saved, regardless of the platform they choose to play on. Let's say that someone is playing Gears of War 4 on the Xbox One, but wants to switch over to play on PC instead: that player will have access to the most recent save of the game because it will also be available on PC.

Microsoft also confirmed that Play Anywhere will include all DLC for compatible games:

"Downloadable content that you buy or earn for an Xbox Play Anywhere game that you own will also be playable on both Xbox One and Windows 10 PC," Microsoft writes on the Play Anywhere FAQ. "This includes game add-ons, Season Passes, consumables and in-game unlocks."

But Play Anywhere is limited to games designed for this system. Fortunately, Microsoft just revealed its first list of games supported by Play Anywhere, including a few that players can really get excited about.

Here is the first round of games developed for Play Anywhere:

• Gears of War 4

• Forza Horizon 3

• ReCore

• Sea of Thieves

• Halo Wars 2

• Scalebound

• Killer Instinct Season 3

• State of Decay 2

• Ark: Survival Evolved

• Cuphead

• We Happy Few

• Crackdown 3

It's likely that Microsoft will continue to add more titles to the list as more developers jump on board to support Play Anywhere. CNET reports that all first-party games developed by Microsoft Studios will automatically support the feature. Yes, that means that gamers can play Halo 6 on the PC.

Microsoft also officially announced the Xbox One S at this year's E3, including more information about its technical specs and its release date: Nov. 22.
