Nintendo has advised those intended to download Lego City Undercover from the Wii U eShop to use an external storage device.
"An external hard drive is required to download this software," warns the official Lego City Undercover site.
Reports suggest that the weighs in at a sizable 22GB, which means an external hard drive or UBS storage device is essential for those with the Wii U basic package.
Wii U Premium owners will likely also need to consider external storage solutions, as a large portion of the consoles 32GB hard drive is reserved for the operating system.
Nintendo previously addressed concerns about the limited storage capacity in relation to digital downloads by saying it has designed the Wii U to support all manner of external devices.
"You can plug in a full-on three terabyte hard drive if you want. I'll love you as a digital consumer," said Nintendo of America president Reggie Fils-Aime.
"The reason we did it that way is that the cost of that type of storage memory is plummeting. What we didn't want to do is tie a profit model to something that's gonna rapidly decline over time. We'll let the consumer buy as much as they want, as cheaply as they want."
In our Lego City Undercover review we said the game "breathes new life into the Lego series" and is "a much-needed quality title for the Wii U library".
