WWE 2K, formerly known as the WWF/E SmackDown! series, SmackDown vs. Raw, or simply the WWE series, is a series of professional wrestling sports simulation video games developed and released annually since 2000. It was co-developed by Yuke's and Visual Concepts from WWE 2K14 until WWE 2K20, when Yuke's had left the development team (Yuke's was the sole developer of the games prior to 2K14). It is published by 2K Sports. The premise of each game in the series is to emulate the sport of professional wrestling, more specifically that of WWE, and present improvements over the previous installments. The games feature WWE match types, storylines and wrestlers.
