TeamXbox reviewed the recently released Halo 2: Multiplayer Map Pack. The jist of it is Bungie Studios released 9 new maps for Halo 2 via Xbox Live, some free, some for pay. You can also buy all these maps on the Map Pack disk, and to make it worth your while they've added some extras to the retail disk, such as a documentary and a short cinematic.
Well on the 6th page of TeamXbox's review, they had posted full version of both those exclusive items for free! Essentially, that negates and main reason to actually go and buy the over-priced disk anyway. I guess someone at Microsoft or Bungie got this, as both clips were taken down in a few hours.
I happened to download them both, however :). When and if I figure out how to upload them, I'll do so for everyone's viewing pleasure.
