8BIT style vertical scrolling shooting game Zelan Force. We developed this product with the idea that we want people to remember the excitement of those days and to pass it on to the next generation. It is a retro-style game that has the same sound as the actual FC machine, limited the number of colors, and eliminates the expressions of modern games as much as possible. Equipped with P・L・S (Pilot Level Score) system! The difficulty level changes depending on the player's skill. As the difficulty level increases, the score increase rate also increases! Challenge your high score in caravan mode! We aimed to create a game that you can enjoy over and over again, such as the feeling of play that changes between offensive and defensive types, and the ability to search for hidden items. story A galaxy far, far away. The inhabitants of the planet Zelan, which was on the verge of extinction due to resource depletion and climate change, were proceeding with plans to develop and colonize other planets in search of a new world. Meanwhile, an incident occurs in which ships departing from Zeran go missing one after another. From the communication records, it is revealed that the series of events was caused by an invasion by Alien Muldark. Eventually, Moldark's forces take control of Zelan's satellite base. Most of the regular army Zeran Force, which was supposed to protect Zeran, had left Zeran to protect the pioneer fleet, so the remaining army faced off against Muldark's army, but suffered a devastating blow. Pilot Levi Kuzier, who was injured and away from his mission, boards the under-development aircraft ``Riserion'' and flies off into space alone in order to take back the occupied satellite base.
