Zen Pinball was a pleasant surprise when it arrived on the PlayStation Network earlier this year. Its impressive social features and fun tables earned it an 8.1 from IGN. Developer Zen Studios promised more tables would be made available as downloadable content, and the first new machine is a tribute to one of the most popular videogame franchises of all time: Street Fighter. For $2.50 you get a fifth table skinned with the cast of Super Street Fighter II Turbo.
