Looking at screenshots of Supergiant Games' upcoming Transistor, it would be easy to assume that it plays similar to the developer's previous game, Bastion. After playing through it at PAX East, however, it immediately became clear that this is an entirely new experience that's every bit as impressive as the studio's first game.
You control Red, a famous singer in the city of Cloudbank that's been targetted by a group of assassins for unknown reasons. After being attacked, she wakes to find herself on the other side of the city. Plunged into a dead man is the same sword the assassins used to attack her with. She pulls it out of the body, and discovers that the dead man's voice and consciousness are now tied to the sword itself. It speaks to her, but doesn't offer any explanation about why she's become a target. It isn't a back-and-forth conversation, as the assassins have somehow taken Red's voice.
