I found out about this game today, so I am sure I am late to the hype since it launches next month on PC, Xbox One and PS4.
Dying Light is an action survival game presented in first-person perspective. The game is set in a vast and dangerous open world. During the day, you roam an urban environment devastated by a mysterious epidemic, scavenging for supplies and crafting weapons to help you defeat the hordes of mindless, flesh-hungry enemies the plague has created. At night, the hunter becomes the prey as the infected grow in strength and aggression - but even more lethal are the nocturnal, inhuman predators that leave their nests to feed. You will need to make use of all your skills and any available means to survive till dawn.
I am not sure if I will be getting this on PC or Xbox One, but it is now on my list. Only thing that is a negative for me is that it only has 4 player co-op and does not seem to have any other type of MP.
