Play Altered Beast - Guardian of the Realms (U)(Venom) Online
Punch your way through skeleton hordes, collect glowing orbs, and mutate into grotesque beasts—werewolves, dragons, even a scorpion that just wrecks everything. Classic arcade jank with surprisingly great GBA pixel art.

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 early GBA wave where a lot of classic arcade properties got portable updates, and this one tried to expand on the original's simple beat 'em up formula with more exploration and RPG elements.
You control a warrior resurrected by Zeus, moving through side-scrolling levels packed with mythological enemies. Your main goal is to defeat the evil Neff and rescue Athena, which involves fighting through screen after screen of monsters, breaking open containers for health orbs, and collecting the three spirit balls needed to transform. The signature mechanics are the beast transformations; each form, like the werewolf or dragon, has its own unique attacks and lasts until you take too much damage. The pacing is methodical, with some light backtracking in larger levels, and the difficulty can feel uneven, especially during some of the more cramped boss fights. It feels like a straightforward action game that occasionally remembers it wants to be something bigger.
