The A-100 Alpha Unit - also commonly known as "Alfie" - is a type of service robot that appears in Binary Domain. These robots were designed for domestic and municipal use rather than combat and are powered by a nickel-hydrogen battery. The production of Alfies has been discontinued, but some units remain in service having been salvaged using scavenged parts. Compared to other Amada Corp robots, Alfies have low-level AI and are rather slow.
