The W.S.S. Delta Team - informally referred to as the "Wolfpack" - is an elite squad of covert operatives employed by World Security Service, the paramilitary wing of the Gia Corporation. In the aftermath of the original unit's destruction, Gia formed a new Delta Team consisting of six members: LUPO, CRIMSON, BERTHA, SPECTRE, BELTWAY, and DEADEYE. In late 2068, Delta Team was dispatched by W.S.S. Command to infiltrate Trident's Hevan City Facility; their orders were to assist the Beta's U.N.O. Alpha Team in their mission to retrieve a sample of the Trident's new weapon the Hexa-Virus from Doctor Eric Sauer, a rogue scientist who betrayed the Gia Corporation by attempting to sell his creation to Trident. However, Delta Team was forced to retreat from the facility after Eric injected himself with the Hexa-Virus while the Betas remained behind in order to complete the mission. A week later, Hevan City was accidentally contaminated by the Corporation's Hexa-Virus, thus forcing Gia to deploy Wolfpack into the quarantined area with orders to commence Operation Biological Downfall. The failure to contain the outbreak placed Gia in a precarious situation for if the world ever learned of their involvement in the destruction of Hevan City, as well as their research in bio-weaponry, the backlash would almost certainly destroy Gia Corporation. To ensure Gia's survival, Wolfpack was charged with destroying all evidence that could encriminate the company, including civilians and H.P.D. officers because any survivor was also an eye witness, and thus a potential threat to Gia's existence. At the same time, the U.S. government sent a detachment of armed troops to enforce the quarantine of Hevan City and to ascertain the nature of Gia's involvement in the contamination of the area. As a result, Wolfpack fought and killed numerous Trident soldiers throughout the course of their mission. Biological warfare was something Gia never wished for, but it happened and there is nothing they can do now.
