Often includes duplicate characters (e.g., 3 versions of Iori). | | Gameplay System | Hybrid system: KOF-style 3v3 team battles, multiple gauge types (Advanced/Extra/EX), Max Mode from 2002 UM, but often buggy or inconsistently coded. | | AI Difficulty | Extremely high. CPU opponents frequently read inputs, perform pixel-perfect combos, and have hyper-armor on many moves. Known as "cheap AI." | | Visuals | Mix of high-res and low-res sprites. Custom screenpacks (menu UI) often styled after KOF XIII or original anime themes. Excessive visual effects (full-screen flashes, multiple projectiles). | | Stages | 50+ stages, ranging from official KOF backgrounds to ripped anime/game stages. Stage music is often custom MP3s or remixes. |
