I received my first in game Mass Effect 3 Wii U freeze today, had to unplug and replug my system. Everything is fine now. Are there going to be updates to fix this.

Could you tell me more of what happend, did the game just freeze while you were playing it? did you get the game used?

I can't help you if you are this vague.

The same thing happened to me. I put the disk in and the WiiU did the update and than the Mass Effect loading screen automatically came up after the update. However the game never started the system froze. Couldn't hit the home button or reset the system holding the power button. Had to unplug the system and reset it and than the game loaded.
