It features a dynamic voiceover from a narrator, and is presented as a two-dimensional game with an isometric camera and a hand-painted, colorful art style. Bastion's story follows the Kid as he collects special shards of rock to power a structure, the Bastion, in the wake of an apocalyptic Calamity.
