The main campaign of Pokemon Legends Arceus is divided into Missions, each with their own objectives that must be completed in a specific order. Missions will begin automatically after you finish the previous one, but you may need to raise your Star Rank with the Galaxy Expedition Team to complete certain objectives.
If you ever need to check your current Mission objective, go to your Arc Phone’s map view and press Y. This will display a list of your current and previous Missions and Requests; from here, you can activate a Mission to have its objective appear on screen as you play.
You can also complete Requests and Research Tasks while exploring Hisui to learn more about the region’s Pokémon and help its residents. Requests and Research Tasks have their own pages where you can learn more about them.
Our Pokemon Legends Arceus walkthrough is organized below by Mission order and the biomes you visit during them. However, this walkthrough contains spoilers for the entire game, so proceed at your own risk.
