Hellblade: Senua's Sacrifice is something of a departure from the usual style of the developer of Heavenly Sword, Enslaved: Odyssey to the West, and DmC: Devil May Cry. Yes, Ninja Theory has created some tense, tight hack 'n' slash combat that won't disappoint fans of their earlier work, but it has a lot more going on besides.
Set in the Viking age, Hellblade: Senua's Sacrifice follows a broken Celtic warrior as she embarks on a haunting, at times torturous and at times beautiful vision quest into Viking hel to fight for her dead lover. It's an exploration of mental health issues that's been designed in conjunction with neuroscientists and sufferers of psychosis. Everything about the game is designed to disorient you. There's no tutorial, no HUD, no objective markers, just a flurry of voices inside your head. The world will unravel around you, with Senua seeing symbols everywhere that will, sometimes, reveal something about your environment.
When you do find yourself with no choice but to fight, everything is heightened by the knowledge that if you die too many times you'll lose your save and be forced to start again.
The effect is a pervasive tension and threat that make Hellblade: Senua's Sacrifice an intense and unique experience.
