Game Guide

In Altered Beast, your main goal is to progress through the levels and defeat the evil Neff. To start, you'll be resurrected by Zeus and begin your journey. Movement is key in this game. You can move left and right using the directional buttons. To jump, press the appropriate jump button. This will help you avoid ground - based attacks and reach higher platforms. One of the most important aspects of the game is the ability to transform into different beasts. To trigger a transformation, you need to collect the souls of defeated enemies. When you have enough souls, a prompt will appear, and you can choose to transform. As a werewolf, use your increased speed to quickly move around the level and dodge attacks. You can also perform powerful claw attacks. When in bear form, focus on close - range melee attacks. The bear's punches are very strong and can take out multiple enemies at once. In eagle form, take advantage of your ability to fly. Fly over enemies and attack them from above. This is especially useful against enemies that are difficult to reach on the ground. As a dragon, use your fire breath to clear large groups of enemies. However, be careful as the fire breath has a limited range. When facing bosses, study their attack patterns. Some bosses may have long - range attacks, while others may charge at you. Dodge their attacks and wait for an opening to counter - attack. Use your beast transformations strategically against bosses. For example, if a boss is flying, transform into an eagle to fight on equal footing. Also, keep an eye on your health. If you're getting low on health, try to defeat enemies quickly to collect health - restoring items. With these tips, you'll be well on your way to saving the world in Altered Beast.
