Pokémon Go’s next version update is a huge one, and Niantic wants to make sure everyone knows it. The developer published a lengthy post that further explains how the new daily quest (a.k.a. Research) feature, will work when it goes live on March 30 — and the details suggest it’s actually game-changing, and for the better.

“Throughout our design process, we focused on the idea that research tasks could accommodate nearly any exploration style–from players who often prefer to go on adventures alone, to groups containing dozens of Trainers–and would range in difficulty to provide a challenge even for experienced Trainers,” the development team wrote. “As a result, you’ll notice that many of these tasks focus on skill and execution rather than depending on random chance.”
