G-Darius is a horizontal shooter similar to Gradius, but with the enemy capture mechanic of Galaga. Enemies are often robotic fish, and different enemies act as different weapons when captured. The bosses seem influenced by DonPachi, with more bullet hell-ish style of attacks. The soundtrack by Hisayoshi Ogura (and others?) is very unique, orchestral hardcore techno with an unusual amount of vocal sounds and dramatic piano.
