Also in 1998, Macmillan Publishing released the Team Evolve-made addon pack for "Battlezone: The Red Odyssey". This expansion contains a new single-player story arc pitting the Chinese Red Army forces against both their allies, the CCA, and their enemies the "Black Dogs". The "Black Dogs" were a roughed-up, beaten-up offshoot of the NSDF with the reputation of ending up with the toughest missions. The Chinese forces introduced both Portal technology that allowed travel outside the Solar System and a 'Cloak', which hid their ships while disabling weapons.
