uh, error tag? her underwear seems to go into her left leg, with part of her thigh being visible underneath it, but it's drawn like her ass/leg ends there.
I don't know if you're fooling around but I'll bite. Xevious is an 80's arcade two layer vertical shoot'em up. One button allows shooting aerial objects while another allows bombing ground targets with the aid of a crosshair. A few born after 2000 know about Xevious or Xevious 3D, but this 40 years old classic game was well known before the millenium.
