User "Lord Friendship" has a well done tutorial on finding and killing BOB 6-S-01 over on HBO:
http://forums.bungie.org/halo/archive36.pl?read=1078377This is technically old news, as his article was posted back in June. Nevertheless, it's germane to what some of us have been doing over in Reach WIP and is definitely worth reading if you care about BOBs.
Scatters and I can corroborate much of what he details, and it seems that the scripting for this BOB spawn may have been less-than-stellar.
I have also contacted His Friendshipfulness and invited him to the SGP. Here's hoping for a new member!
