Once placed upon a surface, these mines will power up and emit a motion-sensing beam parallel to the normal of the surface. When that beam is disrupted, the mine detonates-pretty much guaranteeing the destruction of whoever crossed it. Your scientists have worked extra hard to install a personnel recognition addition to this trip mine-making your facility a safe place for its security guards, but deadly for any intruders. Be certain to register your DNA sequence with the administrator, as is standard company procedure.
