My brother got this game, he likes to play Sonic in high-speed and let me play the werewolf form, it does have ranks in the game, the highest is Rank S. Sonic only get it under the time limit, that was what my brother is doing and what I do is battle more enemies to get enough Gaia Forces to get an increased ranks, along with rings collecting enough to get increased ranks along with the time limit, those are the only three things to do to get a Rank S. The Gaia Forces allow me to increase levels like an experiences points and it might level up the HP, Unleashed Meter, and Attacks Increases, along with new techniques for his werewolf form. The Gaia Forces increase the level and techniques of only his werewolf form that I am doing, I like it, having his werewolf form makes him have an Unleashed Mode to make him invincible and his Attack Powers increasing, along with his hidden moves to combine with his Unleashed Mode and his Attack Moves, I don't even see a Multi-Player mode, including it don't have Wi-Fi.
