Menacer
From Sega Retro
More like a "light bazooka", the user puts the Sega Menacer on his/her shoulder and uses the sight to aim. Came packaged with either a 6-in-1 multicart of simple shooter games or Terminator 2. Uses an infrared receiver which is best positioned above the TV/monitor, and plugs into the controller port. It is similar to the Superscope for the SNES.
