NIS America (NISA) have announced Fallen Legion Revenants during the New Game+ Expo live stream.

Details are scant at this time, and the official website offers little incite as well. Developed by YummyYummyTummy, the game sees humanity hiding from a deadly miasma sweeping the nation within a castle. Said castle is ruled by a madman however.

Play as Lucien attempting to manipulate events within the castle to overthrow its mad ruler, and Rowena in real-time action RPG battles to destroy the monsters roaming the land.

You can find the announcement trailer below.

You can find the full rundown (via the video description) below.

Seek vengeance through steel and secrecy in Fallen Legion Revenants! The world is covered in miasma, and the remnants of mankind have taken refuge in a floating castle ruled by a madman. Swap between manipulating events within Welkin Castle as the cunning Lucien and fighting off monsters in the wasteland below as the vengeful Rowena in this real-time action RPG. Your choices will decide the fates of many!

Fallen Legion Revenants launches 2021 for Nintendo Switch, and PlayStation 4.
