So, I booted up my Halo today to get a few rounds in, and was treated to an update, and thought to myself, "Could it really be THAT update?!!?" Yeah, it was.
The update changes and adds a variety of things to the game, some of which relate to matchmaking settings and changing a few minor things in the maps, most importantly being the blue barrier doors in a few levels, which is odd.
One of the major, and best changes is the addition of around 30 brand new achievements for you to unlock, which is pretty awesome.
The other change is the fact that they now gave each matchmaking mode a unique military rating, instead of a global one like they used to have. This is a bit odd though, as that was what the levels, 1-50, were for...but whatever...all your previous data still stands though, so don’t worry about that getting erased or anything.
So yeah, if you haven’t played Halo 3 in awhile, now may be the time to get back on the Warthog.
