Castlevania: Dawn Of Sorrow Unlockables (DS)

Taking place a year after Aria of Sorrow, the game's protagonist - Soma Cruz - finds himself at the center of a mysterious cult's plan to resurrect their evil lord and master Dracula. To save himself and protect the lives of those he loves, Soma must infiltrate the enemy's home base, a towering replica of Dracula's castle that is teaming with monstrous creatures. Players' abilities develop as they collect items and gather experience points by defeating a multitude of gruesome enemies.

In their quest to defeat enemies, players will use original gameplay concepts that leverage Nintendo DS' touch screen technology. One example is Dawn of Sorrow's "Magic Seal" system. By using the stylus directly on the screen, players must connect a series of symbols in the proper order to unlock an enchanted opening and disperse their enemy's magic into it when they are weakened. The touch screen technology will also be used to destroy "Crystal Blocks."

This ability will allow players to access unreachable areas as well as eliminate obstacles. Nintendo DS' dual screens also allow game information to be readily displayed. During gameplay, the top screen of the Nintendo DS will display an environment map, as well as information on player status, enemy vulnerability, and acquired power-ups.
