Pokemon Mystery Dungeon: Explorers of Time and Pokemon Mystery Dungeon: Explorers of Darkness are to be released on April 20 in North America for the DS.Players take the control of actual Pokemon in both games, traveling through a land free from the humans, who gain pleasure out of imprisoning the poor creatures inside a device no bigger than a tennis ball.
Along the way, they will talk to and team up with other Pokemon who will help them battle their way through a near limitless amount of randomly generated dungeons.
The titles will also incorporate Nintendo Wi-Fi Connection functionality, allowing players to perform 'rescue operations' and send alerts to their friends via e-mail or text.
As always, no word on a European release date for Explorers of Darkness and Explorers of Time. Yet.
