Atlus U.S.A. has released a new trailer for Etrian Odyssey III: The Drowned City, the third chapter in the popular series of exploration RPGs, due to arrive in North America on September 21, 2010, exclusively on Nintendo DS. Etrian Odyssey III transports gamers to a sparkling oceanic paradise filled with atmospheric dungeons to chart and survey, vast watery expanses to sail across, and rumors of a sunken city to investigate. A system of 10 new classes and sub-classes and a wealth of proprietary skills make developing the optimal party absorbing, tactical, and rewarding. The streamlined map maker lets you draw paths, paint in terrain, and drag and drop icons. Up to 5 friends can team up in special combat challenges over a local wireless connection and additional options let you wirelessly trade items.
