During Square Enix's E3 2018 livestream the publisher announced the new title from Platinum Games. The creators of Bayonetta are in fact working on a title called Babylon's Fall which, it seems, will have something to do with a biblical theme, one of the leitmotivs of the most recent Platinum productions.
At the moment we know very little about the game, except that it will arrive in 2019 on PC and PlayStation 4. However, the first artwork shown during the conference was accompanied by some images that depict events such as the day of judgment, suggesting that we will have to deal with angels and demons. The fall of Babylon upon which the title of the game is based narrows things down somewhat.
We, therefore, expect to learn more about the game soon, and the fact that it's from Platinum Games has certainly caught our attention.
