Download Great Battle Fullblast (Japan) ROM – Sony PSP Game

Game Overview

Great Battle Fullblast came out on the PlayStation Portable in 2012, developed and published by Bandai Namco Games. It was part of that late PSP era where crossover games felt a bit more experimental, bringing together characters from different franchises into one chaotic package.

You control heroes like Ultraman, Kamen Rider, or a Gundam unit in a side-scrolling beat 'em up. Your goal is to clear each stage by defeating waves of enemy robots and larger boss characters. Signature mechanics include using screen-filling special attacks that consume energy, switching between ground and air combat, and occasionally piloting larger mecha for overpowered assaults. The pacing is fast, with constant enemy swarms that keep you moving and attacking. It feels like a playful, over-the-top brawler where flashy combos and giant explosions take center stage.
