Sometime prior to the Dark Trooper Project, Kyle Katarn may have had an encounter with the Sissks, after which they maintained a grudge against him.
Behind the scenesEdit
Sissks were invented as a backstory element during the production of Dark Forces, though they don't (at least explicitly) have a role nor are explicitly mentioned in the game or anywhere else. The above is based only on Justin Chin's concepts. Several Trandoshan enemies appear in various levels of the game which may have belonged to the Sissk gang, however.
