The Excalibur Warframe is a sleek, humanoid combat suit with a streamlined design, featuring angular and symmetrical armor plates that emphasize agility and precision. Its surface is smooth with a polished metallic finish, primarily in a combination of white, gold, and blue hues, accented with glowing energy lines that pulse with a luminous blue light. Distinctive design elements include a helmet with a single, central horn-like protrusion and ornate engravings that suggest ancient origins, while its overall form balances between high-detail craftsmanship and functional combat readiness.
