This month's Xbox Live Games with Gold have been unveiled and thanks to Microsoft's backward compatibility for the current-gen console, players on the Xbox One can now get two additional titles that were originally for the Xbox 360, which makes it a total of four free IPs, Major Nelson reports.

Fans on the Xbox One platform, for the whole month of January, will get to receive Double Helix Games and Iron Galaxy Studios' "Killer Instinct: Season 1 Ultra Edition," which has a selling retail price of $39.99. Furthermore, starting Jan. 16 to Feb. 15, the Xbox One game, "Zheros," will become available for users with an active Xbox Live Games with Gold subscription, according to the post made by Major Nelson.

For the Xbox 360 console, "DiRT Showdown," with a selling price of $14.99, is now free for download and will be like that until mid-January, specifically on the 15th. After the racing game from Codemasters, the next title that will take its place is the popular IP "Deus Ex: Human Revolution," which is currently being sold at the Xbox Market with a price tag of $14.99. "Deus Ex" will be available for free until the end of this month.

However, some regions might have different offers and even availability in terms of free games. Major Nelson then added on the post, "Titles are available as free downloads for qualifying Xbox Live Gold members in all markets where Xbox Live is available."

Meanwhile, the Deals with Gold for the first week of January have begun. On a different report from Major Nelson, "Lara Croft and the Temple of Osiris" for the Xbox One platform is now at 75 percent off from its original price of $19.99 and the latest game from DICE, "Star Wars: Battlefront" is at 33 percent off in all of its game pack edition, specifically the Standard Edition, Deluxe Edition, and the Ultimate Edition.
