DemonStar: Secret Missions 2

Secret Missions 2 is the second spin-off of the original DemonStar game. It
uses an enhanced version of the original engine, with more refined textures
and a bigger variety of bad guys. SM2 has its own set of levels (8 in total).

This is a standard top-down space shooter, arcade style. An evil alien race
has developed just another secret DemonStar Fleet to destroy Earth. So, your
job is to battle your way through hordes of enemies, that, of course, want to
kill you.
