Play Altered Beast - Guardian Of The Realms (u)(venom) Online

Altered Beast: Guardian of the Realms came out for the Game Boy Advance in 2002, developed by 3d6 Games and published by THQ. It was part of that wave of games trying to bring older arcade and console concepts to the handheld, a time when you saw a lot of familiar names getting new chapters on the small screen.

You control a centurion resurrected to battle the sorcerer Arcanon. Your goal is to fight through side-scrolling levels across different realms, defeating monsters and bosses to restore order. The core mechanics are straightforward: you punch and kick your way through enemies, collecting blue spirit balls that fill a transformation meter. Once full, you change into a powerful beast like a werewolf or dragon, each with its own unique, screen-clearing attacks. The game moves at a brisk pace, and the difficulty can spike quickly, especially during boss encounters that demand pattern recognition. It feels like a condensed, portable version of a classic brawler, where the brief moments of becoming a monster provide a satisfying burst of power before you return to your human form.
