Advance Guardian Heroes

Lore & Background

Advance Guardian Heroes follows the events of Guardian Heroes. After the Undead Hero was returned to his rest, the heroes were given the option of becoming the Sky Spirit's perfect warriors. The group was divided, with Nicole, Serena, and Valgar joining the Sky Spirit, and Han and Genjiro refusing. Randy escaped back to earth on his own, leaving Han and Genjiro to fight a losing battle against their former comrades. Years later, Zur returns, resurrects Kanon, and uses the power of the Guardian Heroes to take over the world. The few remaining resistance forces call upon the power of the Undead Hero once again, with one young soldier giving up his body to serve as its vessel. Throughout the game, the character fights the previous heroes and earns their power. Ultimately, it is revealed this is another attempt by the heavens to create the ultimate warrior. In the final battle against the ruler of the heavens, all heroes gather to defeat it and subsequently leave for the Other World.

Reader's Guide

Advance Guardian Heroes is a side-scrolling beat 'em up that allows players to move smoothly towards and away from the screen, unlike its predecessor which switched between three planes. The game features physical moves including countering and mid-air dashes, magic attacks that drain the MP meter, and a 'Hyper Mode' that makes the character faster and more powerful. A revised 'barrier spell' renders a character invincible at the cost of magic-over-time and can reflect projectiles and magic. A green anger gauge fills when the player rapidly presses buttons while the character is immobile; when full, the player can activate Hyper Mode. If the character dies, a sinister figure offers invincibility in exchange for the character's soul, leading to 'Devil Mode' for six minutes before destruction. Defeated enemies drop crystals used as experience points to allocate to attributes such as Vitality, Mind, Attack, Defence, Magical Attack, Magical Defence, and Mobility. The game received mixed reviews in English-speaking countries according to Metacritic, with critics praising the visuals and gameplay but criticizing the story and frame rate problems when run on emulators.

Combat & Movement Overhaul

Treasure's side-scrolling brawler for the Game Boy Advance represents a significant mechanical departure from its Sega Saturn predecessor. Rather than forcing players to toggle between three fixed depth planes, Advance Guardian Heroes lets characters glide fluidly toward and away from the camera, creating a far more organic feel in close-quarters fights. The core toolkit blends physical techniques—counters and mid-air dashes—with a magic system that draws from a dedicated MP meter, offering elemental spells and defensive barriers. Two new aerial maneuvers, the air-dash and the homing jump, inject platforming variety into otherwise combat-heavy stages, and their choreography nods to classic 8-bit arcade titles and wire-fu films. A standout addition is the barrier spell, available to every playable character and to enemies on harder difficulties. For a sustained drain of magic, it grants full invincibility; well-timed use can bounce projectiles and spells back at their source or stagger melee attackers. A green anger gauge, built by mashing buttons while immobilized, unlocks Hyper Mode, a timed burst of speed and power that simultaneously replenishes the magic meter.

A Narrative of Betrayal and Divine Schemes

The story picks up after the Undead Hero was laid to rest, when the surviving heroes faced a choice from the Sky Spirit: become its perfect warriors or walk away. The group fractured—Nicole, Serena, and Valgar accepted the celestial offer, while Han and Genjiro refused, and Randy slipped back to Earth on his own. What followed was a desperate, losing stand by the two holdouts against their former allies. Years of silence were broken when Zur resurfaced, resurrecting Kanon and harnessing the stolen power of the Guardian Heroes to seize control of the world. A small resistance, outmatched, once again invoked the Undead Hero, with a young soldier surrendering his own body as the vessel. The player guides this new champion through a gauntlet of the old heroes, collecting their power. The twist: the entire ordeal is another calculated attempt by the heavens to forge an ultimate warrior. In the climactic confrontation with the ruler of the heavens, every hero converges to bring it down, after which the group departs together for the Other World.

Progression, Souls, and the Devil's Bargain

Between stages, players spend crystals—dropped by defeated foes in various sizes and hues—across seven stat categories: Vitality, Mind, Attack, Defence, Magical Attack, Magical Defence, and Mobility. A more potent currency enters the mix when the player defeats the heroes from the original game; each fallen comrade surrenders a soul crystal that boosts a chosen attribute by a flat ten points and raises the character's level regardless of that stat's prior value. Because each successive level demands more soul crystals, allocation becomes a genuine strategic puzzle. Surplus crystals can be banked toward unlocking additional playable characters, and unlike the Saturn original, nearly every unlocked fighter is available in the main story as well as in Versus and Training modes. The game also features a darkly comic death sequence: a sinister figure offers to resurrect the fallen hero in an invincible Devil Mode for six minutes in exchange for their soul. Refuse, and a princess gently reassures you that another chance awaits. Accept, and the character becomes untouchable—though still knockable—before the figure returns and annihilates them. Either way, play resumes from the last checkpoint.

Production Context & Critical Reception

Developed and published in-house by Treasure, Advance Guardian Heroes shipped for the Game Boy Advance on September 22, 2004 in Japan, followed by a North American launch on September 14 and a European release on February 18, 2005, with Ubisoft handling distribution outside Japan. As a direct sequel to the Sega Saturn title Guardian Heroes, it was produced under a license agreement with Sega, making it a cross-studio continuation of that franchise. On Metacritic, English-language critics delivered a mixed verdict. The visual presentation and the depth of the combat system drew consistent praise, with reviewers highlighting the fluidity of the new movement and the satisfying barrier-spell mechanics. However, the narrative was widely panned as thin and underdeveloped relative to the gameplay's ambition. A recurring technical complaint, particularly among those testing the title on emulators, was persistent frame-rate instability that could disrupt the tight timing the barrier and Hyper Mode systems demand. Despite these criticisms, the game stands as a notable example of Treasure's signature high-energy brawler design transplanted onto a handheld platform.
