This strange cca 5m long and 2,5m high robotic unit with the shape of caterpillar is heavy support for Protoss ground forces. The hull is made of pieces connected by joints. The head is equipped with three optical sensors (two on the sides and one on the forehead). It moves with typical slow crawling. Because of it´s slow motion it´s usually transported by a shuttle [...]. Reaver is equipped by micro-manufacturing plant, that produces and stores small robotic missiles - Scarabs [...], under the heavy plating. When fired, Scarab seeks it´s target and explodes on impact, generating devastating electromagnetic fields that cause heavy damage to all in close vicinity. Scarabs move using antigravitional engine closely to the ground with speed up to 100 kmph, but they are not able to overcome larger terrain obstacles. However, they can be launched so, that they use the most of their energy to get in the height of several meters and hit the target on a ballistic curve. In that case, the Scarab has lesser range, but it can overcome obstacles. Reavers can carry only 5 or 10 Scarabs at the time. If they are depleted, the delay between shots is longer, becuase they have to be produced first.
