It did lack content it should have had by default, but is it also one of the most intense mobile Gundam games. Releasing on the vita and ps3 this game should be lite and easier to run on more devices.
The gameplay feels like gundam meets battlefront or battlefield although I haven't played the later. It also is a very challenging, refined (years of them perfecting gundam fighting games) and intense 3d arena fighter which some missions in the main mode alternate to.
