The game takes place in a fictional world in which, shortly before the start of the game, an unknown cataclysm occurred that hit most of the world. Malets, the protagonist of the game, after what happened wakes up in an unknown place and begins the way to the Bastion – a place in the city that was supposed to survive. There he meets the escaped Ruksa (Wanderer), on whose behalf the narration is kept. Rucks tells Maltsa that the Bastion is destroyed, and for its restoration it is required to find the Nucleus.
The Bastion release was a successful debut for Supergiant Games. The game has received recognition among critics and players. The greatest admiration was caused by musical accompaniment and voice-over narration, for which the development team and the composer received many awards and victories in nominations.
