_Supa Nova_ is a bit of a cross between two old Atari games; Asteroids and
Missile Command. As in _Missile Command_ , your job is to kill the enemy
objects by laying an obstacle in their course, but with the difference that
you don’t have any ground missile bases to do so. Instead, as in _Asteroids_ ,
you move your sprite in space, and makes it lay out space mines in the path of
the enemies. And when they run into a mine, they split into two, just as in
_Asteroids_. Since your supply of mines is not unlimited, a refuelling ship
comes onto the screen when you run out. You must dock with it with pixel
precision, and control both its moves (with the cursor keys) and your own
(using the joystick), which makes refuelling the greatest challenge in the
game, especially since all enemies still are moving around while this
precision-demanding task is gone through.
The game runs in four different colour modes, selectable using the C button
and a number.
