I'm usually on evenings after the kids are asleep.

Hit me up sometime.

As for the grenade jump trick, I didn't say it doesn't work, I just said it is time consuming and frustrating. Maybe I should have added "for players who are novices at trick jumps". My wife and I play Halo 3 quite a bit but we've never delved into the trick jumps, etc. That's not our thing. If a player is good at grenade jumping, have at it! From our first try for the achievement, we spent about 40 minutes and never got our team up to the first level of the building. For our second try, we skipped the jump and made it to the top after 25 minutes.

The times you quote are impressive, I would love to see a video or two. As for trying it again, I'd be willing to fill in if someone is having difficulty finding players but I'm no good at that grenade jump so don't expect me to hit that.

Thanks again for commenting! Stick around!

ContactTango here. I'm an avid follower of your site, but this is my first comment. After reading your about your experience doing Annual, I thought I'd introduce myself.

I'm the Admin for a private Bungie.net group called The Spartan I Project. We are the largest B.net group with over 7500 members. Our specialty is the VM: Annual Achievement. I've done it successfully over 200 times and can assure you that the grenade jump works extremely well and is a huge time saver. That jump can also be done with fuel rods, rockets and the hammer.

Our best time is 12:40. A typical run, even with 2-3 rookies in tow takes less that 20 minutes.

I'm sure you'll likely never want to do this achievement again, but if you have any friends or are interested, send me an email. I'll gladly show you some tips.

Keep up the good work.
