Breath of the Wild’s first DLC pack, The Master Trials, comes out tomorrow. This game was released for both the Switch and the Wii U, but there is going to be a difference in memory size when this DLC is available. The Switch version will be 456MB and the Wii U version will be 3.76GB.
If you’re playing this on the Wii U, make sure you have enough memory to be ready to play this on Friday. There has been no comment yet as to why there is such a large size difference between versions.
