(Arcade) Viper Phase 1 (102) Playthrough
1From Seibu Kaihatsu, the maker of Raiden, comes Viper Phase 1.
By the year 2050, mankind begins the colonization of multiple solar systems in search for habitable planets. However, while the colonists establish original cultures and scientific studies, many of them begin feuding with each other and battles break out among them and the Earth. One rebel faction in particular rises to great power and makes Earth their primary target. Earth's response is Operation Viper Phase 1: to combat the rebels using advanced space fighters built from downed enemy ships.
The game is set in outer space. Players pilot the Judge Spear, an advanced space fighter, through eight stages of enemy space fleets and bosses. Enemies include small space fighters, space cruisers, space frigates, and entire space installations.
Gameplay is similar to the Raiden series. A bonus is assessed at the end of each stage taking into account the number of medals collected, the number of enemies destroyed, the number of bombs in stock, and the total kill percentage. At the end of the game, a grand tally is assessed. Factors taken into account are the number of continues used and the number of lives lost.
