Project Sylpheed

Project Sylpheed is an arcade-style shooter and is the follow-up to Silpheed: The Lost Planet on the PlayStation 2. The game's story takes place in the year 2632, five hundred years after humanity left the solar system. Under Earth's rule, 11 different star systems have now been terraformed and colonized.

However, there are a number of groups who object to Earth's rule and desire independence; four of them have joined forces and formed a rebel group called the ADAN Freedom Alliance.
