Thanks to Thumb who stepped up to the plate in our comments section and hit a homerun with some information that has been sending a lot of Google users to our site (over 20,000 yesterday searching for Halo 3 armor). Details on unlocking the different armors that are available in Halo 3’s multiplayer mode are below.
[ed – Also note that Bungie has special "Bungie only" armor with flaming head pieces. This indicates that it’s possible to have other armor than the armor listed below. I feel that it’s possible that we’ll see armor for sale on the XBOX Live Marketplace in the future. Why not?]
Update (Sept 28): We are getting reports that people are running a problem unlocking a couple pieces of armor using our guide. I don’t like to think that Bungie screwed up on their achievements, but I can say that I haven’t unlocked the 5th meta-game achievement just yet even though I have gotten enough points three times on Legendary (and this was while playing through with others as we unlock other meta-game achievements). Thumb says that he had to perform that act that leads to the unlocking of the "Used Car Salesman" three times before he actually got the achievement. I also know people that have had a hard time getting the "Headshot Honcho" achievement, although I think that one is left up to user-error or a poor description of the achievement. Anyone got any feedback?
Got any info to add to the guide? Then get busy in the comment section.
Where’s the Hayabusa skull? We need help finding it.
