In what will assuredly not be the last leak of the summer from Halo 3: ODST as we lead up to its fall release, the entire achievement list has allegedly hit YouTube via Game-Tuts. While the list doesn't reveal any shocking surprises, it does tell us quite a bit about where the game's campaign mode will take us.
According to the list, "Vidmaster" achievements will be making an appearance in the game, as well as all the de rigeur cheevos for regular ol' campaign objectives. Also unsurprisingly, campaign scoring and co-op achievements appear to be making a return in ODST. We'd love to tell you more about the rumored achievement list but, alas, we may start walking into spoiler territory if we do -- and you wouldn't want that, right? You'll just have to head after the break for the whole thing, spoilers in-tow (you've been warned!). We've contacted Bungie regarding the validity of this list and have yet to hear back as of publishing.
