Dave Gilbert announced on the Adventure Games Forum that Wadjet Eye Games would be working on the fifth Blackwell title, Blackwell Epiphany.
According to Gilbert, this title would be darker than the previous titles as Rosa and Joey face a "force" that is powerful and malevolent that it could "destroy the very core of a life in order to get what it wants".
The game is one again written and programmed by Gilbert, with the background and Character sprites being done by Ben Chandler, and the music scored by Thomas Regin. In addition, Abe Goldfarb and Rebecca Whittaker will be reprising their voiceover work as Joey Malone and Rosa Blackwell.
Blackwell Epiphany is due to be released on PC in the Fall 2013.
