It's been awhile since we've heard about the Wii U version of CastleStorm. If you were thinking the project was dead, we have some good news. The title has just received a Wii U USK rating. When Zen Studios was contacted about this finding, they said they have plans “to bring CastleStorm to as many platforms as possible. Timing is always a challenge, however Nintendo fans will be enjoying more Zen Studios games this year.”
