HLMW Will Be released as a 3 episode series. Ep 1 Will Be released on christmas or new year 2020. Ep 2 Will release on 2021. And i'm not sure about ep 3 yet. Ep 1 Will have 6 missions + multiplayer and zombies. And i don't know about ep 2 and 3 but it's safe to say that they Will Be released one Day or another.
Until then goodbye!
