Dariusburst Second Prologue is a horizontal scrolling shooter developed by Pyramid and published by Taito. Being part of the Darius series, it is an offbeat sci-fi shooter set in outer space with aquatic-themed (typically fish-shaped) robotic enemies. The game also features branching paths instead of the linear progression found in most video games. There are a total of 11 zones in the game, with 5 stages per run.
The Android version offers three modes of playing: SP Mode, Original Mode and Mission Mode. Some of these need to be unlocked to be selected.
