Watched a few episodes back in the day, downloaded a few more last week, now I'm hooked. Some of the most well-made Halo Machinma quailty mixed with funny and well filmed live action, really funny and addictive.
WARNING: It may be Halo but it is not some kiddy series, there is some very adult themes and younger viewers are not suggested.
Search Arby n the Cheif on Youtube or look them up in the list of machinima.
