Nintendo decided to hold one more surprise for E3: a brand-new IP for the 3DS from director Histoshi Yamagami, apparently designed by Intelligent Systems, creators of the Fire Emblem and Advance Wars series of games. Codename: S.T.E.A.M. is a turn-based strategy game with some action elements, set in a world where all technology is steam-based. The world is under attack by alien forces, and none other than Abraham Lincoln has commissioned a fighting force of steam-powered units to fight them off. It will launch in 2015.
We'll update this story when we get more details and, hopefully, video or screenshots. And here we are updating this article now with some screenshots. Hopefully we'll have some kind of trailer or gameplay footage for you soon.
