The Witch and the Hundred Knight originally released on the PS3, and centers around a witch (Metallia) trying to expand beyond the confines of her swamp. She summons you, the hundred knight, to help her achieve this goal by any means necessary. You'll be destroying the barriers that are keeping her swamp at bay along your journey via some hack and slash action, but the question isn't necessarily can you free her, but should you?
The Revised Edition for PS4 will carry along the normal graphical improvements, but it will also include a new arena-type mode called the Tower of Illusion. In this mode you can offer up any of your weapons, which will summon a foe of that strength, allowing you to unlock powerful loot in the process, though you will lose the weapon, so there is that. You can also collect catalysts from the tower to enhance your weapons in the main game, and you can even control Metallia herself while in the tower. Even for fans who have played the previous edition, this might be worth a followup look.
Peep the trailer above for a closer look at the game. The Witch and the Hundred Knight: Revival Edition will be releasing on March 1st 2016 for $39.99
