A full announcement will take place on Thursday, November 21 at 21:00 Moscow time. The news was reported on Twitter without providing any other details.
Initially, the game will be subtitled Alyx, said the same insider who previously leaked the gameplay alpha Dota: Underlords.
The leak contained fragments of an interview with The Game Awards organizer Jeff Cayley with the developers of the game, and since it was confirmed, we can assume that Alyx will appear at the ceremony on December 12.
The leak also said that the game should be released in March 2020.
