Styx: Master of Shadows (Xbox One) and Gears of War 2 (Xbox 360) are now available to download for free via Xbox Games with Gold.

The two games replace previous freebies Sacred Citadel and Zheros, and are available to all Xbox Live Gold subscribers for a limited amount of time. To grab them, head through to the Xbox Store.

And don't forget: if you haven't yet picked this month's other Xbox One freebie Hand of Fate, you have until February 29 to do so. PlayStation Plus users, meanwhile, have until early next month to pick up Helldivers and Nom Nom Galaxy on PS4, GRID Autosport and Persona 4 Arena Ultimax on PS3, and Nova-111 and Lemmings Touch on PS Vita.

March's Games with Gold titles have yet to be announced.
