Frostbitten

You spawn in a world where the distance you can see is shortened and you'll freeze if you stay outside for to long. Hordes occasionally appear full of many zombies, resources are buried under the surface to aid you in your survival so that you may create machines that can either destroy or create. (immersive engineering, create  mod), advanced weaponry such as guns may be used to mow down hordes of zombies as you try not to freeze. Many quests guide you of what to do next on your journey and recipes are made easier or in some cases harder. (Modpack still in development, crafttweaker is a pain with removing recipes)
