Wing Commander III: Heart of the Tiger (commonly abbreviated WC3, WCIII, or HOTT) is the critically acclaimed third main game in Chris Roberts' Wing Commander science fiction space combat simulation video game series, developed and released by Origin Systems.

Wing Commander is a space combat simulator intercut with live action cutscenes. Gameplay involves completing missions and destroying enemy craft, Wing commander III dispensed with the issuing of medals after such missions and relied more on cutscenes to drive the story along making much more use of CD technology.
