Digimon World Dawn and Dusk

Digimon World: Dawn and Digimon World: Dusk are two separate Digimon video games for the Nintendo DS handheld game console. They were released in Japan on March 29, 2007. The games' English names were officially confirmed on May 16, 2007. The games were officially released on September 18, 2007.

The two different games appear to have separate storylines and other slight differences.

Plot
A huge earthquake ( caused by a strange virus) has stricken the Sunshine and Dark Moon districts, damaging the access points to the Digital World and causing many Digimon to mysteriously dedigivolve into Digi-Eggs. In Dawn, rumors have spread that the Night Crow Team, from Dark Moon, was responsible for the incident. However, a conflicting report surfaces in Dusk claiming the responsibility falls on the Light fang team from the Sunshine district. With both sides accusing the other, players will take the role of an opposing tamer to investigate and uncover the truth behind the dangerous tremors.

Note that although the games will share a main story, it is known that the plot will differ between Dawn and Dusk to some degree. Players will also explore different areas depending on the version of the game they play. You may choose to play as a boy or girl, though the boy and girl look slightly different depending on the version you play. The two games will feature parallel storylines with a main team in each that opposes the other - Light Fang in Dawn and Night Claw in Dusk - though the two teams work together towards a common cause.

The game also features Marcus Damon, Thomas H. Norstein, Yoshino Fujieda and Keenan Crier, the four main characters of the Digimon Data Squad anime series, in a post-game Union Quest event. In addition, in the same quest, the game features Tsurugi Tatsuno, Yuu Inue and Shou Kahara from Digimon Next.

Gameplay changes
As with Digimon World DS, Dawn and Dusk introduce several new Digimon to the franchise. Chicchimon is a new Bird based Fresh/In-Training Digimon. Grimmon, ChaosGrimmon, and EXO-Grimmon also make their first appearances in the game as the main enemy. Grimmon has a connection with the Chrono Core, the villain of the previous game.

Dawn and Dusk also complete the Digivolution lines of the Digimon from Digimon Data Squad, with the likes of ShineGreymon and MirageGaogamon, after having been left out in the first game. DotShineGreymon and DotMirageGaogamon make their debut, with DotAgumon and DotFalcomon returning from the first game.

Digimon World: Dawn and Digimon World: Dusk also allow DNA digivolution, in which two Digimon of numerically close levels can be combined. Usually, this only provides stat bonuses to the Digimon chosen as the basis of the digivolution, but certain combinations of Digimon, if they have the right stats, will DNA digivolve into completely different Digimon.
