Minecraft is giving away the Deep Sea Mash-Up Pack for the low low price of free from May 31st and June 3rd. All you have to do is log in to your Microsoft account and play some Minecraft.

The Deep Sea Mash-Up Pack includes a new map, ten (10) Deep Sea skins, and a massive underwater world that’s teeming with life and new discoveries. There’s jellyfish, seahorses, ancient creatures of the deep – you name it, the map probably has it!

You can earn one map per person and it’ll take around a week for your free map to become available. Minecraft estimate it to be accessible in your account ‘on or before’ June 12th, 2019, so just have some patience in the meantime.

You can log in to Minecraft with a Microsoft account on Xbox One, Nintendo Switch, Windows 10 edition, iOS, Android and Gear VR. Making a Microsoft account is completely free. You can sign up for one here.
