I still need to get a few achievements on 3 and ODST. Still think I need that "beat the mothership in under 2 minutes" or whatever it is on Reach as well. I'll have to look them up. Not sure that I'm really skilled enough to help out on any of those crazy Vidmaster ones though, especially the one where you have to go through the last level of 3 with 4 players or whatever.
