Citizen Siege - Universe at War Trailer

In this video game trailer, the "First Tiberium War" has begun and the alien race named the "Hierarchy" lands on Earth and they're strip-mining the planet in order to defeat Oddworld (10,000 light years from Earth). When GDI, Novus, Masari, mudokon, gabbit, and grubb forces unite with each other, then the Hierarchy, the outlaws (including Steef), NOD forces, and the glukkons (with the vyykers and sligs) will stand down and give up conquering both planets. The fate of humanity relies on the expatriate, named "Havoc" (GDI commando).
