A distinct variant known as "Shadowtroopers" appear in Star Wars Jedi Knight II: Jedi Outcast, wearing black armour that incorporates a lightsaber-resistant mineral called cortosis. As a project of the Dark Jedi named Desann aligned with a Remnant of the Empire, the Shadowtroopers themselves had been immersed in a Force nexus on Ruusan, temporarily empowering them with Force sensitivity. This armour has a green synthetic gem set into the breastplate which sustained the otherwise temporary effect of their Force empowerment and combines with their abilities to render them near-invisible, with only a faint area of blue discoloration giving them away.
