It has been revealed that one of the Achievements for Halo: Anniversary is to complete the level “Halo” with no vehicle…
I find it easy, but there’s a part I can’t even start imagine being done with no vehicle.
So, does anyone know how to do this jump at 9:20 - 9:25 without the Hog? Nade- or rocket-jumping?
It is extremely easy to do with a grenade jump.
> Nade- or rocket-jumping?
Yes, nade jumping. The level has no rockets.
With Grenade
Ok then, thank you all! 
It would have been cruel if they somehow patched the grenade jump and you had to melee the warthog all the way from the drop-off at the beginning of the level to use as a jumping platform. XD
Cortana: Chief get in that warthog over there.
Master Chief: Warthog? I Don’t Need No Stinkin’ Warthog!
one hour later
Master Chief: Cough Cough Need Water… AHHHH
Cortana: <strong>o_0</strong>

Wow, pretty colors. I’ve always wanted to play Halo with no Warthog.

It would be extremely cruel if they made a typo and put The Maw as the level.
There’s 1 big jump that can’t be made without the warthog on that level.
Just did half of the achievements on the old game the other day and this was one of them. It was pretty easy. Though I missed the jump the first time because of the primitive mechanics.

When I was testing/perfecting (no where near that) the achievements that was my plan be. Needless to say I dropped that idea pretty quick.
