Pokémon Platinum is a role-playing video game with adventure elements. Its basic mechanics are the same as those found in Diamond and Pearl. As with all Pokémon games for handheld consoles up to that point, the gameplay is in third-person overhead perspective, and consists of three basic screens: a field map, in which the player navigates the main character; a battle screen; and the menu, in which the player configures their party, items, or gameplay settings. Players begin the game with one Pokémon and can capture more using Poké Balls. The player can also use his or her Pokémon to battle other Pokémon. When the player encounters a wild Pokémon or is challenged by a trainer to a battle, the screen switches to a turn-based battle screen where the Pokémon battle. During a battle, the player may use a move, use an item, switch the active Pokémon, or flee. Fleeing is not an option during battles against trainers. All Pokémon have hit points (HP); when a Pokémon's HP is reduced to zero, it faints and cannot battle unless revived with a Pokémon skill or an item.
