In case you missed out back in 2012's deal, Telltale's The Walking Dead is available again for half price and as for the first episode it's free to download.
For UK fans that want the game on disc, it's coming out on the 10th May 2013 for £25 (PC's £19). It's on Amazon for pre-order, I'll be getting my own regardless of already having the game digitally. It's THAT good!
Absolutely amazing game!
