Damian Lacedaemion hosts a talk show called This Spartan Life, except that it is done entirely in Halo 2. Yes, you heard me right. The whole thing takes place in the virtual environment of Xbox Live.
The show has its own Solid Gold Elite Dancers (seen in this image), a DJ who spins 8-bit Gameboy tunes, and also has guests who are interviewed by Damian as they walk through the maps of Halo 2. In the first episode, Damian interviews Voyager founder Bob Stein and experimental filmmaker Peggy Ahwesh.
In between an interview, clueless Halo 2 players enter their game (which is really the show being recorded) and start shooting at them, not realising that there are people who just want to hang around a Halo 2 game to talk and record a talk show.
The bit where host Damian takes out an annoying sniper while chatting with Bob was priceless.
