Dual Motives is peppered with inventive puzzles and minigames that take advantage of the capabilities of the Nintendo handheld. In one, Russell tries to gain access to a laboratory. But gaining the attention of deaf Professor Cutter demands an extraordinary solution: Russell assembles a blowgun to shoot little paper projectiles at the Professor, who is immersed in his work. Now it’s up to the player to direct the blowgun with stylus and touchscreen and take aim at the moving target, as well as fire the projectiles with a well-dosed blast of air into the DS microphone.
