Microsoft has revealed A World of Keflings and the excellent Iron Brigade as November’s entries in the Games with Gold programme. The former, which normally costs $9.99, is currently free to download until November 15. It will be replaced by Iron Brigade, which usually costs £6.75 / $9.99, on November 16 until the end of the month.

Games with Gold kicked off in June with Fable 3, which was followed by Defense Grid: The Awakening and Assassin's Creed 2 in July. August’s free games were Crackdown, Dead Rising 2 and DR2 prologue Case Zero, while September's offerings were Magic 2013 and Rainbow Six Vegas. Might & Magic: Clash of Heroes and Halo 3 were free in October.

Games with Gold was announced at E3 in June as a limited time promotion offering every Xbox Live Gold member access to two free Xbox 360 game downloads per month until December 31. But last month, Microsoft said Games with Gold will be offered “as an ongoing benefit for Xbox Live Gold members on Xbox 360”.
