A vertically scrolling sci-fi shooter released for the MSX in 1986. At the controls of the AFX-6502 Zanac, the player battles an organic intelligence across a series of stages using a main shot and a selection of special weapons. Numbered capsules dropped during combat allow the player to switch between different special shots, with consecutive capsules of the same type increasing that shot's power. The system works both ways: the more aggressively a player attacks, the more dangerous the enemies become in return.
