Grim Dawn: Crucible is an addition to the action role-playing game with an isometric camera view in the fantasy setting of Grim Dawn. The grim dawn of a new age, where iron replaced gold as currency and common salt became so valuable that it was no longer used in food. Small, scattered enclaves of survivors exist throughout the world, holed up in shelters. Watching the warring invaders at each other's throats, people began to study the weaknesses and strengths of their powerful opponents. Some of the survivors began to discover strange new abilities in themselves after they were subjected to the warp. Many began to fear such unnatural changes, but, nevertheless, it gave people new hope for creating a resistance capable of fighting otherworldly forces and bringing back the world that had been lost.
The add-on requires the original version of Grim Dawn.
