Alien is a unique midrange from Innova, which combines a special top with the grooves known from the old "frisbees" and a rim like that of a regular midrange. It is stable when you throw it, and it is really good for spin putts, approach shots, and shorter drives.
In this edition, you get a first run, which is the first version of Alien that has been produced. At Innova, you can always recognize their first run discs by the special star stamp.
