Insanity Fight

This shoot ’em up scrolls vertically at constant speed. As well as waves of
aliens, there are lots of mounted structures to be shot before they can shoot
you. One regular enemy is a large spaceship, similar to the goose in SWIV. You
have five lives initially (with extras on offer for every 15,000 points), and
the screen displays how many enemies you’ve killed thus far. It also displays
the high score and (unusually) a bar indicating how high up the high score
table you’ve reached.
