Project Sylpheed

Project Sylpheed, also known as Project Sylpheed: Arc of Deception in North America, is a space simulation video game developed by Game Arts and SETA Corporation and published by Square Enix for the Xbox 360. It was released by Microsoft Game Studios outside Japan. The game is considered a spiritual successor to Game Arts' Silpheed video game series, which comprised 3D rail shooters: players pilot a starfighter, shooting incoming enemies on a vertically scrolling third-person playing field. Project Sylpheed uses full 3D computer graphics and allows the player to instead pilot their spacecraft in any direction.

Project Sylpheed's plot is set in a fictional 27th century where an interstellar human empire is about to erupt into a civil war. The game pits the protagonist and his spacecraft, configured with a variety of weapons and augmentations, against masses of small enemy fighters and large capital warships. The game is interjected at various points with cutscenes that reveal the story. Critical opinions on Project Sylpheed were mixed; reviews varied from considering it an exciting cinematic shooter to calling it a clichéd and complicated simulator. Microsoft considered the game a commercial success in Japan, with it later sold under the Platinum Collection line.
