UPDATE: Microsoft has confirmed that Rayman Legends, Tomb Raider and BioShock Infinite will be March's free Games with Gold, and announced plans to double the amount of free games in April.
While they've yet to be announced, four free games will be available in April on Xbox 360 and two on Xbox One.
ORIGINAL STORY: Xbox Live Gold members will be able to download Rayman Legends on Xbox One, and Tomb Raider and BioShock Infinite on Xbox 360 for free next month, according to a new rumour.
The free games are reported to have been listed on Microsoft's ExpertZone, an online resource for Microsoft's retail and technical support partners, and screengrabbed by a member of NeoGAF.
According to the site, this month's free Xbox One game #IDARB will continue to be available, too.
The listing also states that Microsoft will be "doubling" the number of free games available in Games with Gold in April, suggesting Gold members will receive 2 free Xbox One titles and 4 free Xbox 360 titles during the month.
"You read that correctly," says the listing, "in April, Games with Gold will offer TWICE the free games!"
Microsoft has yet to announce next month's free games or a promotion to double the amount of games with April. But with February coming to an end, expect an announcement imminently.
