Microsoft has revealed the two games to be made available free for Xbox Live Gold members in November.
Xbox Live Arcade titles A World Of Keflings and Iron Brigade will be the two free games featured for November as part of Microsoft's ongoing Games With Gold offer.
A World Of Keflings will be available from Friday November 1 until November 15. Originally released in December 2010, it stars the player's Xbox avatar as a giant in the land of the Keflings, a small race of creatures.
The player has to help the Keflings create their kingdom by gathering resources, building items and monitoring their work.
Meanwhile, Iron Brigade will be available from November 16 until November 30. Originally named Trenched until a trademark issue caused the title to be changed, Iron Brigade is a part tower defence, part third-person shooter game from Double Fine Productions.
Announced at E3 in June, Games With Gold gives subscribers two free games to keep each month, with a new title available on the 1st and 16th of each month.
Originally planned to be a limited campaign to run until the end of 2013, Microsoft recently confirmed that Games With Gold would be an "ongoing benefit" with no end date planned.
October's offerings were Might & Magic Clash Of Heroes and Halo 3. The latter is still available to download for free for the remainder of today (Thursday October 31).
