If you're not a male aged 16 - 24 and your favorite TV channels are not MTV, MTV 2, Spike TV, G4, Cartoon Network, and ESPN then you probably missed out on a great ad campaign for Halo 3.
Because I'm a male, aged 30, and don't watch much TV besides news channels and NFL football, I've also missed out on these ads.
The first four are part of the "Museum" series which are shot as a documentary of soldiers who fought alongside Master Chief.
The last one, "Starry Night," has a similar feel, but you'll actually see some game in there. Oh, and if you are like me, you'll love the Leeroy Jenkins re-mix.
