This expansion consists of an additional punchboard, that provides the player with more (and different) units & vehicles choices. Additional German army counters. Basic game is needed to play with this expansion. From publisher's webstore: "A good war movie would not be successful without proper evil bastards. With the SS troops you will get good value for money. Heinrich Von Kamptz is the worst product from the disturbed mystical mind of the SS; fanatical, bloodthirsty and utterly mad. A monster, a killing machine whose name inspires dread in the heart of even the most hardened veteran."
