Ryu Hayabusa stopped the demonic Tengu, but not before Tengu's destruction was set in motion — a worldwide collapse followed, blanketing the planet in darkness and chaos. With DOATEC unraveling under the influence of power-hungry opportunists, its development division — a military technology fortress — becomes the site of a breakthrough. Dr. Victor Donovan, the architect of Project Alpha and Project Epsilon, completes the Omega Project: the former Hajin Mon clan leader Genra is transformed into Omega, a superhuman entity of unprecedented power. To test Omega's capabilities, DOATEC announces the third Dead or Alive World Combat Championship.
