From what I was told at Gamestop two days ago, the Legendary version will ship w/ a full on highly detailed Master Chief helmet. While I bit on it, and reserved one, do I think it will be as bitchin' as something outa here? Nahhhhh, but at roughly $40-added to the cost of the Halo3 game, I had to do it. They couldn't say it if it was 1/1 scale, I'm thinking it'll probably be smaller. Wearable? Doubt it, probably be just a nice display piece.
There's three versions of the game- Regular, Collectors (in a metal tin, like the last one) or the Legendary w/ helmet.
But, it'll sell out fast, no doubt about that.
