Dying Light is one of my biggest surprises of 2015 so far. Techland actually managed to make a zombie game worth a damn, uniting thrilling parkour and exploration with crafting, brutal combat and terrifying day/night cycles. I still haven't had as much time with it as I'd have liked, but Matt praised the game in our Dying Light review.
Either way, this is a good price for the PC season pass, which includes three new content packs.
