On the shore, Jack acquires a headset, and is directed by a mysterious voice who calls himself Doyle. They open fire and destroy his boat, forcing him to escape and swim for the shore. When he awakes, Carver is startled to find helicopters flying around his boat. Unworried, Jack decides to nap until she comes back.

As Jack attempts to rescue of Valerie, who has disappeared with hardly a trace after the attack on his boat, he uncovers a horrifying scientific operation being performed by a disgraced former member of the major scientific community, brilliant yet with a twisted disregard for moral ethics, Dr. He is soon contacted via PDA by a man named Doyle, who appears to have vast knowledge of the island, the shady goings-on there, and the foes Jack is up against. After being washed up on shore and running for his life, he is knocked out in a close escape and wakes up in the ruins of an old fort. When Valerie goes ashore alone on a jet ski, Jack anchors down shortly before his boat is destroyed by a missile launched by an army of mercenaries occupying the island.
