Taipei is a mission hub unlocked in Alpha Protocol after Operation Desert Spear along with Moscow and Rome. Michael Thorton is informed of a pre-existing Alpha Protocol safehouse that is completely under the agency's radar because of their insistence on complete discretion, deniability, and secrecy by Mina Tang. He enters his new high-tech safehouse and launches Operation True Heirs. His primary mission in Taipei is to investigate the intel he possesses about a possible assassination attempt on the President of Taiwan - Ronald Sung to instigate further instability and hostility between Taiwan (and in extension, the United States) and China, and stop this Halbech-planned plot and hinder their overall conspiracy to start global conflict to benefit their arms sales.
