Phase III Dark Troopers were the most heavily armed and armored class of Dark Trooper.
The first appearance of a Phase III was in Star Wars: Dark Forces, where it served as the game's final boss. They later appeared in Star Wars Galaxies: Trials of Obi-Wan and Star Wars: Empire at War: Forces of Corruption as more common Imperial units.
Empire at War: Forces of CorruptionEdit
The Phase III Dark Trooper in Dark Forces is equipped with the same jetpack and Assault Cannon as the Phase II, but has an additional weapon that fires yellow energy spheres (five at a time). Allegedly, these originally homed in on the player; but due to a bug in the game's code, on all modern systems (Mac and PC) they just float in place, allowing the player to shoot and detonate them to do added damage to the Dark Trooper.
Unlike the Phase II, the Phase III can walk in addition to flying.
Since the Phase III appears at the end of the game anyway, it doesn't drop any items when it dies.
Due to the limited number of enemy types in Dark Forces, Phase IIIs have appeared in many fan levels for the game; however, it's generally considered poor style to use them in a level.
