Back in October, we brought you some information about the still-in-production game, Hellblade: Senua’s Sacrifice, which is being developed by the team over at Ninja Theory.

When we wrote about this one, we talked heavily about how the game focuses on the fact that its protagonist – a young woman named Senua – clearly suffers from some sort of mental illness and, as a result, hears voices throughout her journey in the game. One of the things we discovered when looking into this title, was that the game developers actually did quite a bit of extensive research on psychosis & auditory vocal hallucinations, relying on experts in the field of psychology, and learning from those who actually experience these symptoms.

As Ninja Theory is typically very communicative with fans throughout their creative process, they’ve actually been making video production diaries on the game’s progress over on the website. In one of those diaries, the creative team at Ninja Theory talks more about the research & collaboration they did, in their attempt to make Senua’s hallucinations as true to the real thing as possible.

While fans have been chomping at the bit for more information on Hellblade: Senua’s Sacrifice, and with all of the hard work that Ninja Theory is putting into it, we still do not have a solid release date for it. We do know, however, that the game will first be released on PS4 in 2017. What is also clear, is that if Ninja Theory keeps up the quality of games that they’ve had with Heavenly Sword, Enslaved: Odyssey to the West, and DMC: Devil May Cry, then we can expect a truly epic experience with Hellblade: Senua’s Sacrifice.
