Pokémon Ranger: Guardian Signs (Japanese: ポケモンレンジャー 光の軌跡 Pokemon Renjā Hikari no Kiseki) is the third game of the Pokémon Ranger series. It was released on March 6 in Japan and was released in America on October 4, 2010. The player begins on a region filled with mysterious islands and ruins to explore known as Oblivia. On the launch day, players were able to download a special mission which allows you to capture Deoxys and transfer it over to Pokémon Diamond, Pearl, Platinum, HeartGold, or SoulSilver on multi-player mode. It also includes a multiplayer co-op feature to work together and capture Pokémon. The box art for the game feature a Suicune, Entei, Raikou, Latios, Latias, and Ukulele Pichu. One more cool feature for the game is the brand new "Ranger Signs" to summon certain Pokémon with new abilities, along with the returning "Poke Assist". The main evil team you end up facing is team Pokémon Pinchers.
Unlike the previous Pokémon Ranger series game, Pokemon Ranger: Shadows of Almia, you only have the option of one partner Pokémon during story mode, Ukulele Pichu, however, this is not the case in the past. If Celebi brings you to the past, you get a wide variety of choices for a partner Pokémon. You first start out with Piplup and build up from whatever Pokémon drops a slate. If you pick up the slate and complete the mission, that Pokémon, or one of its evolutionary forms will be able to be called upon and levelled up in a similar way to the Pokémon Mystery Dungeon series. These Pokémon have a Ranger Sign so you call call them up in the story mode as a regular friend Pokémon.
