Microsoft will give away four games to Xbox Live Gold subscribers in March, and is believed to preparing for an eight-game giveaway in April.
The details have yet to be formally confirmed by Microsoft, though the information appears to have leaked on the corporation's ExpertZone website and published on the games forum NeoGAF.
As part of the Games With Gold promotion, those with an Xbox 360 and an Xbox Live Gold membership can download the Tomb Raider reboot for free between March 1 and 15. Then, between March 16 and 31, BioShock Infinite will stand in as the free game.
Once downloaded, the customer technically owns both these games, with no requirement to log online or remain a Gold subscriber in order to access them.
Meanwhile, those with Gold who also own an Xbox One can download Rayman Legends for free throughout the entire month of March. Meanwhile, the party game IDARB extends its free run from February into March. These games can be played as long as the Xbox One owner has an active Gold membership.
Along with this, Microsoft has announced that more than 100 million games have been played through the Games With Gold promotion.
"To celebrate, we're giving customers more of what they love by doubling free games in Games With Gold for April," the company said.
