Well it just so happens I have a friend who downloaded a pirated torrent of ODST and played the campaign on a modded box. (For the record I do not support this illegal activity. Nor does this site in case the eyes are watching...)(No its not me, it is seriously a friend who did this, Grif is currently angry at him (or jealous)) Spoiler (Move your mouse to the spoiler area to reveal the content) Show Spoiler Hide Spoiler Turns out, the Vidmaster Achievement "Classic", which requires you to complete a level on Legendary without firing a shot or using a grenade, is quite easier than you might think. There is a ghost on the third level that you can use throughout the entire level. Just a little tid bit of info I thought ya'll might like to know. If I'm not supposed to post this due to legal issues, feel free to lock and remove this.
