This huge robotic walker is similar by design to Expander. It strides across the battlefield on four tall, slender legs which give it an extremely high level of mobility. The great height of the machine allows it to step up and down cliffs and other steep elevations with little difficulty, and gives it a dominating field of fire. Above the central section is heavily armoured main section, going high up to 25 m. It carries two powerful thermal lances: one mounted on each side of its body. Complex focusing and targeting systems are used to pinpoint the continuous damage output of the thermal lances for optimal efficiency. As a target is destroyed, the lances are switched to a new target instantly so that a colossus' beam cuts a fiery swathe of destruction through multiple enemies with each firing cycle. The colossus is unusual for the fact that it was created purely as a war machine. Most protoss robots are created for industrial or resource-gathering purposes. The design is centuries oldj, but the Conclave outlawed the manufacture of colossi, and existing machines were deactivated before being sealed away in distant asteroids and uninhabited moons. Centuries later the war against the zerg has brought forth these engines of destruction to do battle once more. [1]
