"Dark Forces", released in 1995 by LucasArts, has been regarded as one of the first "true 3-D" first-person shooter games. Its engine, the Jedi Engine, was one of the first engines to support an environment in three dimensions: areas can exist next to each other in all three planes, including on top of each other (such as stories in a building). Though most of the objects in "Dark Forces" are sprites, the game does include support for textured 3D-rendered objects. Another game regarded as one of the first true 3D first-person shooter is Parallax Software's 1994 shooter "Descent".
