When I put Overlord into my 360 it says I must update the software otherwise I cant play the game. Is this going to update my firmware on my 360.

I second this question. And what if the disc is for example a PAL disc and I have a NTSC Box?

Not sure about the updates,buti wouldnt take the update if oyur using pal disk in ntsc console.

The game contains the FALL UPDATE from 2006 for the dashboard, dosen't affect firmware AT ALL.

btw: the game is fun!!!
