IGN writes: "Treasure's 1999 Nintendo 64 shooter Bangai-O holds a special place in many a gamer's heart. The developer was already beloved for titles like Gunstar Heroes and Radiant Silvergun. Bangai-O was one of the quirkier offerings from Treasure, featuring an insane amount of enemies and bullets onscreen. Almost a decade later the game has finally been updated for the 2D-friendly Nintendo DS. Not really a port and not exactly a sequel, Bangai-O Spirits includes a mix of old and new levels. But significant new features have been added, like four-player co-op and a robust level editor. It needs to be said, though: this game is for the hardcore only. A sinister voice laughs at you when you die, for Pete's sake. Unless you're a masochist shooter fan that enjoys a real challenge, Bangai-O Spirits is likely to frustrate you."
