About this game
A frantic multidirectional shooter from Treasure, released for the Dreamcast in December 1999. Players pilot the mecha Bangai-O — firing shots in all eight directions simultaneously — against waves of enemies. The game's signature EX bomb mechanic turns defence into offence: the more enemy bullets on screen when the player triggers it, the larger the counter-attack explosion. Created by the same studio behind Gunstar Heroes and Radiant Silvergun, Bangai-O distilled Treasure's design philosophy into a concentrated, physics-driven spectacle.
Key Features
Bangai-O fires in all eight directions at once, and the EX bomb — charged by collecting fruits — releases a burst of shots proportional to the number of enemy bullets on screen at the moment of detonation. Puzzle-like level design requires players to manage the EX bomb timing carefully. The game also contains extensive dialogue sequences with eccentric humour.
The Story Behind
Bangai-O arrived during Treasure's most prolific creative period, when the studio was releasing several defining shooters — including Radiant Silvergun (Saturn, 1998) and Ikaruga (Dreamcast, 2001). The Dreamcast version improved on the N64 original with updated graphics and sound, and the title helped solidify Treasure's international cult reputation. The EX bomb mechanic, where more danger creates more power, became one of the studio's most celebrated design ideas.
Tricks & Tales
The original version of Bangai-O was developed for the Nintendo 64 — an unusual choice for a Treasure title, which usually targeted Sega hardware. The Dreamcast port arrived just 13 days after the N64 version in Japan. The eccentric in-game dialogue was largely the work of Masato Maegawa, Treasure's co-founder, who wrote the script personally.
