lasering...i just like how it says LASERED lol makes me laugh also i like doing multi team on xbox live and getting me and my friend camping at these spots with a hammer each we get like 20 points before any of them get 5 lol
to be honest i haven't really gotten anything great, the thing that was most fun that i've done is hit my friend's vehicles with a gravity hammer and watch him fly.
the people who don't know the passwords are the guys who did voice acting for Red Vs Blue. And my favorite moment was when i gave headshots to 5 dudes in a row. not standing in a row lol.
A great moment in Halo 3 for me was when I put on the IWHBYD skull and Grunt Birthday Party skull and then a grunt says "Merry Christmas!" and then I gave it a headshot.
