Dual Destinies continues the style of gameplay from previous installments, in which the player must utilize evidence and find contradictions in witness statements to prove their client innocent. Like previous installments, gameplay is split up between Investigations, in which players find evidence and question witnesses, and Trials, where they must use the evidence to expose contradictions. The game now features full 3D graphics and character models, allowing more dynamic camera angles during gameplay, such as quickly panning around the courtroom in the moments before a dramatic reveal. The 3D camera also allows investigation sequences to take place in 3D spaces, permitting greater investigative depth, such as being able to rotate around a room to look for clues.
