Promethean Crawler

The Promethean Crawler is a type of autonomous Forerunner machine, and the most common type of defensive construct encountered on the artificial world of Requiem. They are small, quadrupedal machines capable of both ranged and close-quarters combat, using a small beam as their primary weapon. Crawlers are ferociously aggressive, having been specifically designed to hunt down and eliminate any foreign threats. They travel in large packs and work together to destroy enemies by overwhelming them from every conceivable angle. Crawlers consist of a basic unit, a more heavily armed unit, and a long-range unit.
