The Xbox Series X is a home video game console developed by Microsoft. It was released on November 10, 2020 as the fourth generation of the Xbox console family, succeeding the Xbox One family.

Rumors regarding the consoles first emerged in early 2019, with the line as a whole codenamed "Scarlett", and consisting of high-end and lower-end models codenamed "Anaconda" and "Lockhart" respectively. Internally, Microsoft had been satisfied with the two-console approach for the Xbox One, and planned a similar approach for the fourth generation Xbox, with the target for the high-end model to at least double the performance of the Xbox One X. The high-end model was first teased during E3 2019 under the title "Project Scarlett", while its name and design as Xbox Series X was unveiled during The Game Awards later in December.
