The Hatch Breaker Limpet Controller is a compact, rectangular device with a sleek, metallic casing, designed for mounting in a ship's utility slot. It features a series of small, glowing blue indicator lights along its front edge, signaling operational status, and a slightly recessed control panel with tactile buttons for activation. The surface is smooth with a matte finish, accented by subtle branding and technical markings etched into the metal. Its design is utilitarian yet advanced, reflecting its purpose in breaching cargo hatches with precision-engineered limpets.
