Developer 11 Bit Studios announced today that Frostpunk, the game about humanity's final, desperate bid for survival in a great frozen wasteland, will be out on April 24. To celebrate the launch date announcement, the studio also released a new cinematic teaser offering a gentle reminder of the risks of getting things wrong. 

Frostpunk is set in an alt-history 19th century in which something, somewhere, has gone terribly wrong. The world is encased in ice, and humanity stands on the brink of extinction. As the ruler of the last city on Earth, you must build and expand your steam-powered citadel, establish rules and laws, harness resources, push back the cold, and send out expeditions in search of information, supplies, and other survivors. The primacy of survival means hard decisions will have to be made, but there will be consequences—for the city, and for you.
