Publisher Atlus today announced a quartet of games for the Nintendo DS, including a duet of music games, a sequel and a half to Touch Detective, and a new entry to its soap opera/sci-fi surgery sim series Trauma Center.

In Draglade, combat will be mixed with music as fighters battle for rhythmic supremacy. Centering around a weapon called the "Glade," which generate tones when used in combat, players will need to follow the beat and use their reflexes to survive. Features include customizable characters, unlockable characters, and multiplayer over both local and online wireless connections.

In another foray into musical games, Ontamarama will have players conducting "sound spirits" to create a musical symphony on the DS. The microphone will be combined with touch functionality to test the timing abilities of would-be maestros. 12 stages of play will be available, with a story mode and three difficulty settings.

Touch Detective 2 1/2 aims to continue BeeWorks' series' offerings of humorous adventure, with five new episodes, twice the locations of the original, and all-new characters. Side quests with unlockable bonus art will keep detectives busy.

Finally, Atlus' Trauma Center: New Blood for the Wii will improve upon the original entry by adding a two-player cooperative mode. New Blood will also feature a new story, characters, and operations, displayed in 480p at a 16x9 aspect ratio. An online score ranking system will be supported.
