The 2015 E3 convention saw many new games and tech being unveiled and hinted at. Bethesda seemed to come out with the more appealing material that dominated the attention of fans with their showcasing of Fallout 4 and also more importantly perhaps, Doom. While the latter has been anticipated ever since Fallout 3 was released on the Xbox 360 in 2008, and New Vegas in 2010, it was without a doubt Doom that was the show stopper. The gameplay demo was revealed with a remix of old music and familiar foes within the dazzling in-game demonstration.

This was alongside Microsoft announcing that Windows 10 will have complete compatibility with Xbox One and also the unveiling of their new Elite Controller. However the most pertinent  information released was that after months of requests and speculation, the Xbox One will have reverse compatibility with 360 titles, or as they have labelled it, Backward Compatibility. This comes at an important time as Microsoft have been losing the console race against the PS4 since release. However, best of all, Xbox One Backward Compatibility will be available at no additional charge, so you won’t have to pay to play games you already own.

Microsoft claim developers will not need to port their Xbox 360 games over to the Xbox One. Customers will have two ways to load old titles. If you bought an Xbox 360 game through Xbox Live, you will be able to simply re-download it on the Xbox One. If you own the game on a disc, the Xbox One will copy it to its hard drive, but still check for the physical disc before launching the game. Old Xbox 360 games will be able to take advantage of new Xbox One features, like capturing and uploading in-game screenshots.

It is unclear at the moment which Xbox 360 games will allow backwards compatibility; Microsoft are looking to release backward-compatible titles in waves. The first wave includes Banjo-Kazooie: Nuts & Bolts, Hexic HD, Kameo, Mass Effect, and Perfect Dark Zero, among others. You can check out the complete first wave here, but based on information found on Neogaf, fans should expect Halo: Reach, Halo 3: ODST, Borderlands, Gears of War, and Alan Wake, as well as other titles, released in future waves. I personally cannot wait to see games such as Gears 2 coming on to the Xbox One while we wait for Gears 4 to arrive (which was also featured at E3 and the gameplay demo can be found here).

Xbox 360 backwards compatibility will be available for Xbox Preview users immediately, with standard Xbox One owners getting it in a system update later this year. I would recommend keeping your Xbox 360 until then, and check out all the releases and announcements yourself from this years E3.
