In a 2012 PlayStation.Blog post written by Chris Sorrell (the creative director of Primal), Mark Gibbons (the lead artist behind Primal) expanded upon the comments Paul Donovan made in 2005. Gibbons confirmed that once Primal had been finished, there was some preliminary work made upon a sequel. Gibbons also revealed some of what Primal 2's story would have been about; that it would have featured Jen's lover Lewis as the central character, and would have told the story of Lewis' journey through Oblivion's version of Hell, back to Jen in Mortalis.
