Altered Beast: Guardian of the Realms for Game Boy Advance

Zeus, creator and ruler of the Guardians of the Gates, raises you from your grave! You must go fourth and defeat a new, unknown evil that has destroyed the Guardians and ravaged the universe. To do so, you must collect the keys and Essence of each land, transforming you into beasts with unnatural powers and special abilities. Conquer this evil and you will become the sole Guardian, the protector of the universe. Orbs of Essence transform you from a man into 13 unique wild beast creatures like Dragon and Scorpion. Battle and fight your way across 16 worlds, each inspired by Greek mythology. Engage in combat with ranged, melee, and magical weapons. Collect power-ups like Shockwave and Venom for special attacks. Two multi-player modes: 2-player Co-op Story Mode and 4-player battle arenas.
