Nioh and Nioh 2 (including all DLCs) are also bundled in the Nioh Collection on PS5.
There’s still more to Nioh even after having finished the game for the first time. After completing the Main Missions (up until the Demon King Revealed), you will unlock an extra Mission called The Queen’s Eyes. You’ll also gain access to one of every Divine Weapon in the game. Clearing The Queen’s Eyes unlocks New Game Plus – The Way of the Strong.
New Game Plus – Way of the Strong
Once you’ve cleared The Queen’s Eyes, New Game Plus will be available (Way of the Strong). At first, you will only have access to the first three Main Missions and Side Missions. After completing them, all other Missions will be available.
This harder version of the game features stronger enemies with increased health and attack, but also higher Amrita and Gold yields, and equipment drop rates (including Divine Weapons). This is a good time to farm for weapons and armor that you might have missed during your first playthrough of the game.
