Complete the game once on the default difficulty (Cowboy) to unlock a video of artwork that shows the various stages of Jericho's character development.

Throughout the game, you'll view various cutscenes that show the story of Darkwatch. As you view these cutscenes, they will become available for future viewing in the Extras menu. Completing the game will unlock most of the available cutscenes, though there are a couple of extra ones that depend on whether you made good or evil decisions. You can go back to previous levels to unlock the cutscenes you missed because of your decisions—the movies you unlocked the first time will remain unlocked, but all progress after the level you replay will be erased.
