Gamma Emerald Gameplay and Storyline Walkthrough

Story on a mysterious island

In Pokémon Gamma Emerald, you take on the journey to your new home; however, an unexpected storm appears, causing your boat to crash.

The island holds ancient secrets waiting to be uncovered.

Start a new mission as a Pokémon trainer

Very soon, you will see a briefcase with 3 Pokeballs, get your starter, and begin your adventure on the mysterious island, capturing and training Pokémon. Of course, you are not alone; Team Magma and Mercenaries are also on the island, seeking to uncover its secrets and take its power to fulfill their mission.
