+space this game provides an environment with movement in four directions and
+six planes of rotation.  Initially the game explains the 4D control system via
+a graphical sequence, before moving on to 30 levels of gameplay with numerous
+enemy, ally, weapon and mission types.  Features include simulated 4D texturing,
+mouse and joystick control, and original music.")
