Transistor is a sci-fi themed action RPG from the creators of Bastion that invites players to wield an extraordinary weapon of unknown origin as they fight through a stunning futuristic city. The game seamlessly integrates thoughtful strategic planning into a fast-paced action experience, melding responsive gameplay and rich atmospheric storytelling. During the course of the adventure, players will piece together the Transistor's mysteries as they pursue its former owners.

Red, a famous singer in a city called Cloudbank, is attacked by the Process, a robotic force commanded by a group called the Camerata. During the clash, she is transported all the way across Cloudbank and comes into possession of the mysterious Transistor- the greatsword-like weapon she was to be assassinated with. The Transistor is buried into the chest of an unnamed man, now slumped over and dead; though his consciousness and voice seems to have been absorbed into the Transistor itself, along with Red's voice. The Camerata continues to track Red and the Transistor down with the Process, wanting the weapon for some yet-unknown cause.
