Phenotrans

Phenotrans is a very greedy corporation and an antagonistic organization from Dead Rising 2 to Case West. They were responsible for causing outbreaks both in Las Vegas and Fortune City.

Events between Dead Rising and its sequel
Phenotrans created an anti-zombification drug known as "Zombrex" presented by Isabela Keyes. Since she and her brother Carlito were responsible of Willamette outbreak and she would be arrested, she has no choice, but to work for Phenotrans to produce Zombrex.

Las Vegas outbreak
While Zombrex was overprofitted, Phenotrans was running out of Queens they needed, thus they created a gas substance that attracts and causes regular zombies to be mutated that create more Queens to develop the medication.

Phenotrans unleashed Queens in the city to infect people.

The government ordered a firebomb to destroy Las Vegas.

Fortune City outbreak
Raymond Sullivan, under Phenotrans' order, unleashed the zombies to infect the city.

While the military arrived, Phenotrans unleashed a gas that infects the soldiers.

Phenotrans still can blame Chuck for the outbreak.
