As the 7th Columnist notes, there are two things that can be taken away from this new data, apart from the actual achievements themselves. The first are the single player levels, which at this stage include the following:
- Jungle
- Base
- Outskirts
- Voi
- FloodVoi
- Wasteland
- Citadel
- High Charity
- Halo
It seems you get an achievement for completing each one of those. Of course the list will most likely change, as will the names themselves. Second is the return of the skulls from Halo 2, although this time you unlock an achievement for discovering each one.
