This is a cosmic shootout in the atmosphere of this category of games from the 80's. An unwavering plot associated with the realization of a constant mission to reach the farthest possible corners of space, a fierce fight against enemy units, a ship-boss at the end of each hand, a mass of explosions, shots, various types of weapons and bonuses - these are constant and permanently recorded standards for games of this genre, which we also come across in Hydorah.
