I need to go get the achievement from ODST for doing a level with 0 shots fired. Now perhaps those who have done it can clarify something for me.

I watched the IGN insider moves video on how to get this one, I know the level to use is the reserve level when you have to drive the hog over the level and out the other end. Now Paul tells me you cannot have a gunner or passenger with you but their video said you can have both and actively encourages the player to give the spartan laser to their passenger in the hog. This is because the laser will then due to the rules of NPC weaponry have infinite ammo and can be used to target the enemy tanks that continuously harass you.

Now, what I need to know is who is right, IGN or Paul...also is there any tips people can give for doing it. I tried the IGN route before, completed the level (was not very easy to do) and didn't get the achievment for the completion of the level.

Edit also I be in need of a vidmaster final level party for Halo 3. Paul is/was being gay and refusing to be party to it however if we can get enough of us together who he actually enjoys playing with perhaps we can have some hilarious ghosting action done.
