## Description
In 21th century the Earth became overpopulated, and humans began building
colonies in the solar system. Technological expansion led to widespread
pollution; in order to counter it, a powerful computer Naious was built. One
century later, humans became completely dependent on Naious, and that was when
it stroke unexpectedly. European cities were reduced to ruins after a single
attack. The fighter spacecraft ASP and its pilot Manami Katagiri were dealing
with a possible rebellion on Jupiter when it became clear that the future fate
of humanity depends on them.
_Naious_ is a horizontally scrolling shoot-em-up. The gameplay is fairly
traditional and involves navigating outdoor and indoor stages (often with
narrow spaces), destroying mobile and stationary enemies on the way. The
fighter craft starts with a vulcan gun and can later change to wide shot,
laser, and homing missiles. Rather infrequent power-ups appear at set points
on the stages and change or enhance the plane’s weapons.
