An alarm is triggered and armed security guards begin to appear. After convincing a scientist to open the lab door, Michael is able to grab the chemical weapon. Michael is armed with a stun gun and is responsible for taking out the scientists and other employees encountered along the way. From there, the three advance through the halls. Once inside, the three swim through the shaft until they reach the interior of the lab. The three dive and approach an underwater exhaust shaft to gain entry, the player as Michael must use a torch to cut loose a grate over the shaft's access point. Michael and the agents, dressed in scuba suits, take a Dinghy down the San Andreas coast to a spot near Humane Labs and Research. Haines instructs Trevor and Franklin to handle transport, while Michael joins the agents in infiltrating the lab. However, he and Norton agree to join the heist. Haines is angry due to a lack of manpower (he claims that he told them that it's a six-man job, when he actually didn't). Haines wants the protagonists to steal a chemical weapon from the Humane Labs and Research, an IAA research facility. Soon, Agents Haines and Dave Norton arrive. Michael, Franklin, and Trevor meet at Cape Catfish.
