Parkour never made anything less cool - just look at the opening of Casino Royale or the entirety of Mirror's Edge. So mixing up parkour with zombies was not only inevitable, its pretty much essential. So good job Dying Light!
The game is an open world parkour and zombie mashup where you're tasked with foraging and being stunty during the day before running away and hiding at night when the walking dead get extra super powerful for some reason. And the map is set to be really, really big, at least according to this PlayStation Access video which shows you how long it takes to get across the map.
There's a lot to see, and a lot of things that are trying to kill you. There's a flavour of Dead Island here - which isn't at all a bad thing - but the open world and the day/night cycle makes it seem much more interesting. I bet its even more fun when you don't have to listen to the inane commentary as well.
Dying Light is coming to PS4 , Xbox One and PC on the 20th of January 2015.
