A system of simple map, movement, and command rules designed to be used with any skirmish miniatures rules. The designer says: "FGS is a simple system to be used as a support for skirmish miniature rules. The idea is quite simple: to provide a mechanism to make it possible to move your figures without any ruler while keeping the special 'feeling' of the 3-dimensional terrain." "FGS is composed of two parts: the Movement System and the Command System; both systems can be used independently: the Movement System can be easily introduced on every existing skirmish rule to allow an easy management of the figures on the 3-dimensional map. The Command System can be used to create non-deterministic sequences of play."
