The Walking Dead:: The Complete First Season is available now on Xbox One globally and PlayStation 4 (in North America only so far, no word on when it will go live in Europe). The Telltale Games title is available for $24.99/£19.99 and weighs in as a 4.65GB dowload. It was originally announced for a 21st October release (21st in the UK) but seems to have made its way out now.
The Complete First Season contains all five parts of the episodic series plus the 400 Days bonus episode. In it, you play Lee Everett, a convicted criminal, who is given a second chance of freedom and redemption in a world of undead where he meets and protects Clementine.
