Sonic Unleashed (Mobile)

Sonic Unleashed (Mobile) is a version of Sonic Unleashed for use on mobile phones and to be released in Europe. This game was announced at E3 2009. It contains 11 levels and retains Sonic's ability to transform into the Werehog. All the graphics come in sprite form making this game comparable to a common 2D platformer. Unlike the console versions, Sonic has the ability to go underwater without dying, much like traditional 2D Sonic games.
