The combined forces of Checkmate and the Outsiders work to infiltrate the mysterious Oolong Island, base of operations for Chang Tzu's Science Squad in the events leading up to World War III. Aside from dealing with a giant monster, the infiltration proceeds as planned, the group splitting up into support and exfiltration teams, as well as the group to infiltrate the fortress. But it seems that there's a leak somewhere... Oolong Island is expecting them.
