Universe at War: Earth Assault (UAW:EA) is a sci-fi real-time strategy game developed by Petroglyph Games and published by Sega, intended to be the first of the planned UAW series of games. As a whole, Earth Assault can be seen as a sort of full-scale celebration of science fiction history, with many a sci-fi reference - for instance, while the Hierarchy Walkers are remiscient of "The War of the Worlds", Mirabel's suit, Viktor, possess Eastern (i.e. Japanese) mecha designs and features whilst Masari designs seem to be based upon ancient civilisations.
