Writes C Bob “SebabDukeBoss20”:

Abduction 4.0 is an erotic flash game based on Duke Nukem 3D.  It plays like a Japanese bishojo game.  Ever wondered what the aliens were doing with all those kidnapped women?  Find out!  Follow Crystal, a naive young secretary who has been abducted by the aliens for their sinister purposes.  Guide her as she explores Space Stations, Alien Vessels, and Los Angeles during the alien invasion.  There are over 25 endings and loads of Duke Nukem 3D game references and humor to keep you entertained.  The game also includes older versions of the flash game.
