How it plays

How does Altered Beast play?

The game uses a side-scrolling perspective. Move through five stages, defeat waves of monsters, collect spirit balls from special white-headed enemies, and reach the stage guardian.

Collecting three spirit balls changes the warrior into that stage's beast form. The transformation grants stronger attacks and different movement options, but it is temporary. Players can walk, crouch, jump, punch, kick, and use beast attacks while advancing through each linear stage.

Plan your run

What is the best way to play Altered Beast?

Prioritize the white-headed enemies that carry spirit balls, but avoid taking unnecessary damage while collecting them. Three balls are required for the transformation, and the powered-up form is usually the safest way to handle dense enemy groups.

Save the transformed attacks for difficult enemy patterns and the stage guardian. Learn when to crouch or jump rather than attacking continuously, since enemies can surround the warrior quickly.
