NBA 2K18 may still be a little over a week away from release, but PS4 and Xbox One players have a chance to dive into a portion of the game a little early. The game's Prelude demo is now available to download on both consoles.

Like its name implies, The Prelude offers players a chance to get an early start in the MyCareer mode. It also gives them a chance to experience the Neighborhoods mode, the game's new shared social space. Here, players can customize their player's appearance, play mini-games, and hang out with other players.
