Force & Gravity Powers
A supplement for the BASH! Ultimate Edition RPG focused on Force and Gravity powers. It includes dozens of powers organized into Hard Light, Kinetic Energy, High-G, and Low-G facets, along with new Enhancements, Limitations, Disadvantages, and rules for creating custom powers or characters at random. The volume also introduces the Membership Advantage, allowing heroes and villains to belong to organizations with access to bases, vehicles, equipment, contacts, and backup, while facing enemies, internal threats, and public scrutiny. Gravity powers can manipulate movement, weight, flight, walls, crushing forces, and even black holes.
