These screen shots come from the actual Jedi Knight gameplay. These pictures were taken off of Jedi Knight Outpost so give the credit to them and visit there page on my links section.

A Lightsaber face-off, just like in the movies.	Using the 3rd-person viewpoint, you can get a good look at the action.
A Tusken draws his blaster.	Jedi Knight features enemies of all kinds, including these giant winged beasts called Mailoc.
Here Kyle falls down through one of Jedi Knight's huge rooms.	Notice the great architecture and lighting present in this screen shot.
A Stormtrooper takes aim at Kyle in this very red room.	Jedi Knight's engine is completely "true 3d", allowing walls and floors at any angle.
