Microsoft announced during their 2015 E3 press conference that Xbox One would be compatible with Xbox 360 games through an upcoming software update. This is all done through For Xbox 360 games that you purchased digitally, you'll be able to re-download them using your Gamertag. If you own a physical Xbox 360 game, you can play them by simply inserting the disc into the Xbox One.

Games that are currently listed include:

• A Kingdom for Keflings
• A World of Keflings
• Alien Hominid HD
• Banjo-Kazooie
• Banjo-Tooie
• BattleBlock Theater
• Defense Grid
• Geometry Wars Evolved

• Kameo
• Mass Effect
• N+
• Small Arms
• Super Meat Boy

• Viva Piñata

Rather than having a blanket emulator that can play all Xbox 360 games, the games have to be added individually. Microsoft has a site that allows users to vote on which games should be added next, with Red Dead Redemption, Call of Duty Black Ops II, and Elder Scrolls Skyrim on the top of the list http://xbox.uservoice.com/forums/298503-backwards-compatibility. IGN reported that their Xbox 360 emulator could not function with USB peripherals such as external hard drives or Kinect, meaning that Kinect games are not supported by the backwards compatibility.

The speaker mentioned that you would not need to pay an additional fee in order to play the games you already purchased. Possibly making a jab at Sony. Sony only allows you to play PlayStation 3 games on the PlayStation 4 buy renting them through PlayStation Now, their streaming service.
