5 members of the U.B.C.S. were sent to a food facility in Raccoon City to save Dr. Chamelon. The names of the members are: Claus, Normen, Ed, Roberto and Roger. With a special tracer they try to find the doctor.

The newest member, Roger, seems to know more than the others and the team leader, Claus, has got a bad feeling about this mission.

They fight against living dead creatures and then they loose Roberto....

So that the chaos is perfect they also lost the track of Dr. Chamelon. Now they decide to go to the middle of the town. What they don't know is that a T-Virus infected crow follows them.

A new track leads the team to the sewer. Ed shall wait at the entrance while the others go into the sewer. They find a secret room and in there waits a mutated dog. And Ed also has got a problem. The T-Virus infected crow attacked him. No one of the others knows that....

After they killed the dog they find the ID card of Dr. Chamelon and now Roger is able to download some files from the main computer. Now he tells the others what Umbrella's plan was. They once again wanted to collect fight data.

Some minutes later they found out that Dr. Chamelon is already dead. They're going back to the entrance of the sewer and hear a scream.... it's Ed!

They're trying to help him but it's already too late. Ed mutated into a super monster with unbelieveable power. The team decides to run away because they don't have a chance against it. Some seconds later they're surrounded by Zombies..... This fight will be their last one....
