From the makers of Heavenly Sword, Enslaved: Odyssey to the West, and DmC: Devil May Cry, comes a warrior’s brutal journey into myth and madness.

Set in the Viking age, a broken Celtic warrior embarks on a haunting vision quest into Viking Hell to fight for the soul of her dead lover.

Created in collaboration with neuroscientists and people who experience psychosis, Hellblade: Senua’s Sacrifice will pull you deep into Senua’s mind.
