Highrisers (Steam) PC Key GLOBAL

Humanity has been struck by a mysterious prion disease, which left those infected trapped in an eternal dream. Unable to wake up, they transformed and changed into the mysterious dreamers: sleepwalking, zombielike creatures that shun the light.
They now dwell in the dimly lit urban canyons of the cities and the lower levels of highrise buildings, hiding away from the sun; only to come out at night, trying to get those who still resist.
Four survivors are stuck on a skyscraper in a desolated metropolis, and only through tenaciousness, tinkering and teamwork will they prevail.
