Descent II is a 1996 first-person shooter video game developed by Parallax Software and published by Interplay Productions. It is the second game in the Descent video game series and a sequel to the original Descent. Unlike standard first-person shooters, the player must control a flying ship that has a six degrees of freedom movement scheme, allowing the player to move in any 3D direction. The game received very positive reviews from video game critics. Like its predecessor Descent, Descent II is a six degrees of freedom shooter where the player controls a flying ship from a first-person perspective in zero-gravity. It is differentiated from standard first-person shooters in that it allows the player to move and rotate in any 3Ddirection. Specifically, the player is free to move forward/backward, up/down, left/right, and rotate in three perpendicular axes, often termed pitch, yaw, and roll. Aboard the ship, the player can shoot enemies and fire flares to explore darkened areas.
