Pokémon Ranger: Shadows of Almia

The game takes place in the Almia region. The player begins as a Pokémon ranger-in-training at the Ranger School and quickly graduates to a rookie Ranger and must advance from there. Much of the gameplay is similar to the original game. Players must capture/befriend wild Pokémon to aid them by circling them with their Nintendo DS stylus (known as a Capture Styler in the game).
