Altered Beast: Guardian of the Realms is a side-scrolling action game where you play as a dead guy resurrected by Zeus to rescue realms from an evil monster named Arcanon.
You visit 15 different realms, fighting your way past dozens of monsters in each one to battle and defeat the boss creature at the end. Your attacks include kicks and punches, and you can jump or duck to avoid enemies.
A new feature is attack items that give you useful abilities like regeneration, increased speed, and shields.
You can battle your friends using a link cable in story mode with creatures you collect throughout each level.

Manual
Game Guide
Extracted from the original game manual
In this mythological action game, players assume the role of a fallen hero imbued with the power to absorb elemental essences. The objective is to reclaim the Hall of Realms and defeat the Dark Reaper Arccanon, who has stolen the keys to the multiverse's gates. By collecting Spirit Balls and restoring lost Altered Beast spirits across various planes, the player must restore the balance of power between order and chaos.
Story
The Balance of Power
There is a fine line between order and chaos, preserved by the will of Zeus alone. From his throne on Olympus, Zeus maintains peace throughout all planes of existence. Guardians, chosen by Zeus, safeguard access to the Hall of Realms. This hall serves as a nexus to the multiverse.
The Threat of Arccanon
A Dark Reaper named Arccanon seeks to upset this balance. He has attacked Zeus' Guardians and stolen the keys to the Realm Gates. He intends to create armies across the multiverse and attack Olympus.
Your Mission
Zeus calls upon fallen heroes to defeat Arccanon and his minions. You must reclaim the Hall and restore the balance. As a Guardian, you are imbued with the power to absorb the essence of each plane. These essences appear as Spirit Balls held by Arccanon's thieves, the Spirit Suckers.
Collecting Essence
Collecting Spirit Balls will transform you into an Altered Beast. You must travel to captured realms to recover lost Altered Beast spirits and Gate Keys. Never give up and emerge victorious against Arccanon.
