Fable 3 is currently free on XBL Marketplace. The way to download it, is by adding it to you queue, and clicking “use Microsoft Points” even if you don’t have any available – and start downloading. You still have to be an Xbox Live Gold member though, otherwise it will run you 3600 MS Points. No idea if this is a mistake or not as we have yet to see a promo for it, but go ahead and try.
Buy our t-shirts, yeah
They're far more stylish than your average video game website tat.
