The Xbox Store receives the complete first Season of the episodic zombie title over a week before scheduled release.
Due to be released on 24th October next week, Telltale's The Walking Dead has appeared on the Xbox Store over a week earlier today.
You can buy the game now on the Xbox Store for £19.99, even though it still states a release date of 31st October 2014.
There's no sign of the game on PSN for PS4 at this moment in time however.
The Walking Dead: The Complete First Season is made up of five episodes bundled together in one package, along with a bonus episode - 400 Days. Players take on the role of Lee, a convicted criminal on his way to jail, until the undead show up and send him down a completely different path.
