This mod introduces a brand-new and unique vanguard faction to the X4: Foundations universe—the Apus Stellar Treaty (AST), featuring its own unique capital ships and equipment.

Whether you are an industrial tycoon who loves peaceful station building or a stellar commander eager to build an invincible fleet, this will be your perfect homeport.
