Case 7-2: The Only Lead

Case 7-2: The Only Lead is a case in Dead Rising 2. Chuck Greene travels down into the underground tunnels to investigate the source of the mutagen gas blanketing the city. After fighting past mutated Gas Zombies and a group of Mercenaries, Chuck reaches the entrance to a secret laboratory, where he witnesses a strange device which emits a sonic frequency that causes the heads of a group of nearby zombies to explode. Several Queens fly out of the bodies, and are sucked up into a large vacuum tube in the ceiling. Chuck enters the lab and encounters two scientists, Mark Bradson and Pearce Stephens, who attack him. Chuck kills both men, then accesses their laptop computer. Though he is unable to stop the flow of gas to the surface, Chuck does find some disturbing information: the scientists were working for Phenotrans, the company that manufactures Zombrex. Realizing that the company must be the ones truly responsible for the outbreak, Chuck takes the laptop and heads back to the safehouse, eager to clear his name and give Rebecca Chang the story of a lifetime.
