Since this generation of consoles began in late 2013, the border between beta and demo has become nebulous. The term beta is reserved for multiplayer experiences that are started so that development teams can collect actionable feedback. In contrast, demos give players a free hand with a piece of a finished product. According to game director Jonathan Warner Anthem will deliver the best of both worlds with closed alphas and a public demo.
In an interview with VG247 Warner addressed some of the confusion surrounding the two terms beta and demo. Asked if Anthem will have a beta, Warner replied, "Ah, a demo, you'll have the chance to play the game early and we want to talk about it at PAX."
Up Asked to clarify the differences between beta and demo, Warner responded, "Well, I think there's something weird there, we're going to test the game in closed alphas, and then what's being shown in public is a demo."
Therefore, anthem does not appear to have any related beta that Call of Duty: Black Ops 4 where Treyarch actively updated the game based on player feedback. Rather, Anthems pre-launch plans include closed alphas and a demo for the public to try. This demo will probably be part of the game in its "finished" state, allowing consumers to try it before they buy.
Currently, details of closed alpha tests are not publicly known. The same goes for the demo Warner talked about. However, as he noted, concrete details should come from PAX West starting on August 31
Anthem early next year on the PlayStation 4, PC and Xbox One on February 22, 2019.
