Official description

Original English source text provided by IGDB.

Every hero changes the heroes beside it. Arrange 46+ heroes on a grid, chain their abilities, and find the layout that multiplies your damage. Then prestige across 21 worlds, fight with mounts, and run missions, mines and a workshop while you're away.
