"Star Wars: Dark Forces is a first-person shooter video game developed and published by LucasArts. It was released in 1995 for DOS and Apple Macintosh, and in 1996 for the PlayStation. The storyline within the Dark Forces is set in the Star Wars fictional universe and follows the character Kyle Katarn. Katarn is a mercenary working on behalf of the Rebel Alliance. He discovers the Empire's "Dark Trooper Project", which involves the building of powerful robot soldiers.
Dark Forces uses the Jedi game engine, which was developed especially for the game. The engine adds gameplay features to the first-person shooter genre which were uncommon at the time of release. These features include level designs with multiple floors and being able to look in all directions.
Critics gave very favorable reviews for the DOS and Macintosh versions of Dark Forces, but not for the PlayStation version. The DOS and Macintosh versions were praised for the level design and technological advances. The PlayStation version was criticized for having poor graphics and slow frame rates, reducing the playability of the game. A sequel to Dark Forces, Star Wars Jedi Knight: Dark Forces II followed in 1997."
