engine. Developed primarily by a French team (notably brothers Icare and Shaka), it is widely considered one of the most high-quality Saint Seiya fan projects due to its custom high-definition sprites and fluid animation that mimic the original anime style. Core Gameplay & Features
The game features an expansive selection of characters, including:
The character sprites are often ripped from older official games (such as the Saint Seiya: The Hades PS2 game or the Saint Seiya: Brave Soldiers titles) but have been meticulously converted and edited to function in a 2D plane. The animation frames are fluid, capturing the iconic poses of the characters—the way Seiya adjusts his headband, the fluid movement of Shiryu’s Rising Dragon, or the menacing aura of Phoenix Ikki.

The screen pack (the user interface for the game) is drenched in Saint Seiya iconography, featuring the Pegasus constellation, the Gold Cloth boxes, and the font styles used in the manga.
