Eidos have now released two new maps for Battlestations: Pacific over Xbox Live Marketplace, with a version to hit Games For Windows Live on June 25th.
Costing 560 Microsoft Points, the pack adds Volcano and Choke Point to the list of maps with Duel, Siege, Escort, Island Capture and Competitive modes for one or both; enjoy.
Volcano is an island map whereas Choke Point has a narrow channel of water to battle over. Battlestations: Pacific has you in the boots of several roles in the Pacific World War 2 theatre, meaning you get to pilot aircraft and navigate naval vessels into thick combat.
