From the back of the book: Weapons of war and valor. Catapults and ballistae are the weapons of yesterday's armies, impersonal tools of warfare that were imprecise and whose loyalties depended on the crews manning them. Doom Striders presents a new type of weapon designed for more heroic play styles and face-to-face encounters. Whether you're looking for a weapon to throw at your opponents in the next mass combat encounter, or an effective offense against a dragon guarding its horde, you'll find something within hte pages of Doom Striders.
