Each month, Xbox Live Games subscribers anticipate brand new Gold games offered for free. For June 2015, three prominent names have surfaced recently in the rumor mill. This includes "Ryse," "Forza 5," and "NBA 2K15."

According to Product Reviews, Xbox One owners should look forward to have a big game for E3 2015 next month which could have the same caliber as "Rayman Legends."

Other games being considered by Microsoft for Games with Gold are "Ryse" or "Forza 5," the news outlet reported. These games still don't have a "AAA" title, so it's safe to assume that Microsoft will grant them that as soon as it gets released.

Gospel Herald suggested that there's a possibility that "NBA 2K15" could be available for free in May 2015, given that the game was also offered for free during the last weekend of April. This news, however, isn't official yet and Xbox Games with Gold subscribers should watch out for news and other surprises.

More positive news is in store for "CastleStorm: Definitive Edition." Gospel Herald wrote that the definitive edition of the game will be offered for free and will include the original campaign and two additional expansions: from Outcast to Savior and The Warrior Queen. It's also equipped with 20 new single player battles, 4 new extreme survival battles, and 10 new magic spells, among other brand new features.

For those unacquainted with the game, the Xbox Store describes "Castlestorm" as "a super genre mashup of 2D physics destruction mashed with tower defense brawler...It's Knights vs. Vikings...where medieval warfare meets 2D physics-based destruction!"

"Pool Nation FX," on the other hand, will also be offered next month. The billiards game consists of photo-realistic graphics and real-world physics, Gospel Herald noted.

For the Xbox 360, Xbox Live Gold members have access to the action-adventure game "Mafia II" as of May 1, the news outlet added. The game was made by 2K Games and was released as a follow-up for 2010's "Mafia: The City of Lost Heaven."

Another game available for the Xbox 360 is car racing game "F1 2013," which features 11 teams and 22 drivers competing in 19 circuits and in the Grand Prix, Gospel Herald wrote. A classic edition also showcases drivers, cars, and circuits inspired from the 1980s and the 1990s.
