• The 5200 version (picture #1) has a different menu from the 400/800 version (picture #2), but otherwise it’s the same.

• BUG: Unlike the arcade version, the Swarmers don’t fire behind themselves!  The programmer forgot to program them to.  {Steve Baker}

• BUG: For some reason, waves 87-89 have only a few Landers, and no additional mini-waves of them will appear.  There’s also an abundance of Bombers.  They’re often referred to as “Bomber” waves since so many appear.  {Scott Stilphen}

• BUG: The wave counter only goes up to 99.  At a result, the game will also reset the number of humanoids back to 10 every time you clear a wave!  {Scott Stilphen}

• BUG: Having too many smart bombs in reserve (the exact number is unknown) will reset the number to 0.  {Scott Stilphen}

• BUG: Having too many ships in reserve (the exact number is unknown) will end the game.  When you end the wave, your points will be totaled, and then “GAME OVER” will appear!  {Scott Stilphen}

• BUG: If you score 10 million points or more, the last digit in your score will flash faster, and parts of it will always remain visible.  {Scott Stilphen}
