Project Giant Robot, an upcoming Wii U game from famed Nintendo designer Shigeru Miyamoto, has been delayed. As part of Nintendo's latest earnings report today, the company listed a release date for Project Giant Robot as "TBD." Previously, it was penciled in to launch in the first half of 2015.

　　The first half of 2015 ended on June 30. Nintendo did not share any kind of explanation for the delay.

　　Project Giant Robot (working title) was unveiled alongside another experimental game tentatively called Project Guard at E3 2014. That game is still set to launch sometime in 2015, though neither a full name nor a specific release date has been announced for it.

　　Designed by Miyamoto and his team, Project Giant Robot is one of Nintendo's tech experiments the company is undertaking to show off the unique capabilities of the Wii U GamePad.

　　The game involves a fight between towering robots--and it sounds quite exciting based on our time with it.

　　"You swing the left and right sticks to swing your robot’s left and right arms, and you plod forward using the right trigger," we wrote in our preview from 2014. "The robot's orientation is controlled by the GamePad's gyro, so you need to swing the thing around as you punch to try and build up the required momentum to floor your opponent. These robots fight against a backdrop of skyscrapers, with the GamePad screen taking a first-person view and the TV itself showing the robotic brawl from a helicopter."

　　Another Wii U game recently delayed was The Legend of Zelda, which is also now listed as "TBD."
