UPDATE: It appears the permadeath save wipe doesn't actually happen, and Ninja Theory has bluffed gamers.
Ninja Theory adds unique bold and gutsy finality to its new game, adding weight to everything you do.
If you die too much while playing Ninja Theory's new macabre, atmospheric and visually creative new title Hellblade: Senua's Sacrifice, then the game will wipe your saved data. The adventure is about eight to nine hours long and features a number of challenges that often put you in harms way, and the permadeath system is quite controversial in the gaming sphere.
SPOILER WARNING: If you haven't played the game, and want to keep details of the permadeath system a surprise, then look away now.
