Nintendo has launched Pokemon Mystery Dungeon: Explorers of Darkness and Pokemon Mystery Dungeon: Explorers of Time, both for the DS, in stores in North America.

Both games, developed by Chunsoft, have players waking up as a Pokemon, tasked with creating exploration teams comprised of Pokemon to determine who has been messing around with time itself. Building on the previous Pokemon Mystery Dungeon games, players explore randomly generated dungeons while pursuing the plot.
