If you hop into No Man's Sky today, you'll receive a radio broadcast from space. Specialist Polo, the alien imp typically found chilling in the mysterious space anomaly, has a quest for you. And not just for you but for everyone, because No Man's Sky has begun hosting community events. Participate, and you'll earn Quicksilver, a currency you'll be able to spend on new emotes, cosmetics, and base decorations at a new vendor aboard the anomaly.

The current event takes place over the next week. Polo will give you coordinates and direct to you a nearby portal. Activate the portal with the coordinates, and you'll be transported to a planet where you'll be asked to dig for buried technology capsules. You'll probably find lots of other players there, too, and maybe one of them will be blasting Wayne Brady's game show Let's Make a Deal over their open mic at an excruciating volume. Or maybe that was just my personal community experience.
