This first weekend is PS4-only and lasts until October 17th at 1PM Eastern. Xbox One owners will have to wait until the second weekend, which runs from October 21st through the 24th, to join in. This isn't a long time to play, and you won't get a taste of the single-player game (nothing new for CoD betas). However, it might make all the difference if you're at all concerned that Infinite Warfare might be more of the same.
