The
original title/version was Hover Force 3-D, and was to use
chromostereoscopy glasses (commonly known under the ChromaDepth name).  After
INTV Corp picked up the rights to Mattels Intellivision properties, programmers
Steve Ettinger and David Warhol increased the intelligence of the
enemy, and graphics artist Joe King took out many of the color cues that
worked with the glasses.  {BSR}

When
first turned on or reset, the game will flash a standard title screen (picture
