Repulsion Device

Force fields are energy-based barricades found in technologically advanced areas of the wasteland in Fallout 1, such as the Mariposa Military Base in the Northern region and the underground base beneath the Cathedral. Yellow-colored force fields may be temporarily disabled by utilizing the "Repair" command on the force field emitter. It is possible to pass through red-colored force fields without disabling it; however, this will result in varying amounts of HP damage. Dogmeat is said to have succumb to death by attempting to pass through a force field in the mutant military base in The Vault Dweller's Memoirs.
