No Man's Sky might have launched in a disappointing state, but developer Hello Games has been hard at work ever since, adding features and tweaking the game to make it better line up with fans' expectations. A big free update just landed on all platforms right as the game came to Xbox One for the first time. Called Next, this update includes a multiplayer mode, better base building, and graphical improvements. To celebrate the update, several retailers have put No Man's Sky on sale.

Pricing varies wildly depending on your platform of choice. Since the Xbox One version is brand new, it's not surprising to see that it's the most expensive version you can buy. It's $50 nearly everywhere except for Amazon and Walmart, where it's $42. This version is Xbox One X-enhanced, so it looks especially nice if you have the right hardware.
