The Rockman X DiVE development team just announced via Facebook that a new skin will arrive next week on Wednesday, October 21st after the maintenance period.
As you may recall, Iron Maiden was Cinnamon's Hyper Mode in Rockman X Command Mission. Unfortunately they didn't announce if she will be freely distributed or purchasable like "Yukata Pallette" which was available for 800 EM for a limited time. It now goes for 1200 EM.
Let us know in the comments if you'll be picking this one, especially if it's something you have to purchase as opposed to getting it free by playing an event.
