Playthrough of Zaviga, Data East’s vertically scrolling arcade shooter, developed and published by Data East in 1984. Released in March, it is an obscure but interesting early attempt at expanding the Xevious-style formula with a vehicle that can freely transform between a ground-based tank and a jet fighter. The concept gives Zaviga a distinctive identity, although its endless structure and fairly limited variety prevent it from becoming one of the standout shooters of its era.
Rating: 6/10
You begin the game as the CX-19 in tank form, driving along the floor of a large canyon. Movement is controlled with an eight-way joystick, while two buttons handle your attacks. Your craft carries forward-firing laser cannons as well as bombs, with a targeting sight in front of the vehicle showing roughly where the bombs will land. The screen constantly scrolls upward but can also pan somewhat left and right as you move, making the playfield feel wider than many vertical shooters from the period.
The central mechanic is the ability to transform between tank and fighter forms at almost any time. As a tank, you travel directly across the terrain and can attack enemies on the canyon floor, but touching the walls or other solid terrain costs a life. Transforming into the jet raises you above the landscape, letting you safely fly over many obstacles while continuing to shoot airborne enemies and bomb targets below.
It is a clever mechanic because the two forms effectively operate at different heights. Remaining airborne is generally safer, while descending places you directly among ground defenses and environmental hazards. Unfortunately, the game never develops the concept as far as it could. Once you understand the advantages of the jet, there are long stretches where staying airborne is the obvious choice, reducing what initially appears to be a highly tactical transformation system.
Enemy design is reasonably varied for 1984. Alongside conventional aircraft and ground installations are strange robotic and insect-like machines, and later sections introduce hazards such as giant floating rocks and enemies associated with aquatic areas. The landscape also contains different routes through the canyon, giving the scrolling terrain a slightly more exploratory quality than a simple straight corridor.
At intervals, the scrolling stops for Zaviga’s closest equivalent to boss battles: enormous cannon installations built into the canyon walls. Progress requires destroying their vulnerable glowing sections before the scrolling resumes. These encounters provide welcome breaks from the otherwise continuous action and are among the game's more memorable visual elements.
Graphically, Zaviga is colorful and quite detailed for an arcade shooter released so early in 1984. The contrast between the canyon floor, machinery and unusual enemies is effective, and the transformation between tank and fighter gives the player's vehicle some personality. It lacks the immediately recognizable visual style of Xevious, however, and repeated terrain eventually becomes noticeable.
The sound is similarly typical of its period: simple electronic music, laser effects and explosions that do their job without being particularly memorable. Technically, the game is interesting as Data East's first title to use the Motorola 6809 CPU. Mamoru Kanda served as main programmer with Akira Sakuma as sub-programmer; Sakuma would also program B-Wings, released by Data East later in 1984.
Zaviga does not have a conventional sequence of numbered stages or a proper ending. Instead, its world continues looping indefinitely, gradually introducing new enemies, obstacles and greater difficulty. The objective is therefore ultimately survival and high-score chasing rather than reaching a final boss. This structure was hardly unusual for 1984, but it means the game becomes repetitive once its major ideas have been revealed.
Despite that repetition, Zaviga is an appealing curiosity from Data East's early arcade catalogue. The ability to move between ground and air levels was an inventive idea, and its combination of forward shooting, bombing and terrain navigation gives it more character than many forgotten shooters of the period. It never quite turns that concept into enough meaningful strategic depth, but for fans of early scrolling shooters or B-Wings and Xevious-style games, Zaviga is certainly worth experiencing.
