Nioh the Souls-like samurai action game currently has a limited time demo. The demo begun today and will end after the weekend on Jan 23.
Those who play the demo will gain rewards at launch depending on what they accomplish. Finishing the Main Mission will give the player the Ogress Headgear. Completing the harder Twilight Mission will grant players the Mark of the Strong and the Mark of the Conqueror. To keep the Ogress Headgear save data from the trial will be needed while both Marks will require a DLC download that also need to be kept until the full release.

While compared often to the Souls series, Nioh has a number of differences that set it apart. Beyond the obvious Japanese setting and inspirations, Nioh also differs greatly in gameplay. The two largest differences are the Ki and Stance systems. Ki, the equivalent of stamina, can always be regained quickly by a well-timed button press after using any amount of Ki. Players can also gain less Ki but recover it faster by activating recovery earlier. The three Stances (low, mid, and high) affect Ki use and have other unique properties. Each Stance has different combos, skill trees, and uses different amounts of Ki.
For a quick overview of other differences the PlayStation Blog has a short article. The official Nioh page also has an overview of the combat and the game as a whole.
Nioh releases February 7 exclusively for PlayStation 4.
