The first thing you have to know is that there are 3 research levels in the game, it can be increased through expeditions, specifically through expedition points, which as you get more and more will increase your research level little by little. Little.
You will be able to obtain expedition points as you complete the missions to capture photos of the Pokémon, although you can compare the photos and send the best ones to obtain more points. We hope that after reading this guide on how to level up research in New Pokémon Snap, you can understand the process of increasing the research level quickly well.
