The players Valkyrie can change its appearance and abilities by switching between its three forms: Fighter, Gerwalk, and Battroid. The Fighter form is the fastest but lacks an automatic cannon, the Gerwalk form has an automatic cannon, but is slower than the Fighter form, and the Battroid form has an automatic cannon and can also shoot behind itself, however it is also moves slower than the other two forms. All forms come with a limited supply of homing missiles that can be used.
