For the Cause (also known as Final Encounter) is a 2000 American direct-to-video science fantasy film directed by David Douglas and Tim Douglas.

Plot

For the Cause is set in the late 26th century on a distant planet that has two human colonies. These colonies were founded as a refuge from the wars of Earth, but the vision died when the colonies began fighting a hundred-year war, reducing their once mighty cities to rubble. The stone walled city of Brecca is the northern neighbor of the nation of Obsidian, a culture of black glass cities and unfathomable technology. The war drags on with the vestiges of once mighty technologies, and the great armies are now but orphaned teenagers, fighting and dying for a cause they never knew. Unless the war ends, yet another entire generation of children on both sides will perish in battle.
