The instructions and a bonus microfig. The gun it's carrying has a bar stud on the side.
The parts in the set. Two of those odd Stud w/Vertical Bar, Jumper plates, two 1x1 Plate w/Bar (closed ends), and the 2x2 Plate w/Dual Horizontal Clips are always useful. There are a couple of printed pieces which is nice. Then there's a 1x2 Modified Brick w/Bar Hole that's intriguing me.
