Sony today revealed its November lineup of free games for premium members and Microsoft, bless its little white cotton socks, has too. November's 'Games With Gold' titles for Xbox Live Gold members will be Double Fine's Iron Brigade (née Trenched) and A World of Keflings.

Kingdom-building sequel A World of Keflings will be free from November 1 to 15th, explains, while the tower defense Iron Brigade November 16 through to the end of the month. Both games usually cost $9.99 apiece.

They follow on from October's offering of Halo 3 and Might & Magic: Clash of Heroes.

Do remember that you only need to download them during this period then you'll be yours forever, even if you stop paying for Gold membership. Microsoft had planned to only run Games With Gold until the end of this year, but it's now to run indefinitely with two new games each month.
