Acme

Acme (likely Acme Robotics) was a defense contractor for the American government. As per contract 10056-567, it designed, manufactured and supplied humanoid combat robots for the US military, however, they were never widely deployed, for reasons unknown.

Appearances
Acme brand robots appear only in Fallout Tactics, although it seems likely that the tech provided necessary groundwork for the creation of androids in the MIT.
