Psychic Storm

The game's stand-out feature, however, is its transformation mode. Each of the characters can transform to a larger and much more powerful biomechanical insect-like ship. The transformation can be performed at any time as long as the correspondent bar, which refills itself over the time, is not empty. The bar is reduced rapidly when the character is transformed; special power-ups can be collected from vanquished enemies to extend it temporarily, but once it is depleted the character transforms back to his or her normal form.
