I have a slight dilemma. BOBs are meant to spawn only once every level, right? If yes, then I think I might have discovered something.
Moving on,
A few days ago, I was playing Nightfall on easy difficulty. I came across a good old golden Ranger. No biggy. Now, a checkpoint after that, I came across another BOB (at least I think it was one...), only this time it wasn't a Ranger or even white, but a golden Elite Minor. I took a thorough look at it before sniping it and its fellow blue Minor patrolling next to it in their heads, and indeed, it was in fact a golden Minor. And no, it was not a white Minor duel-weilding Plasma Rifles.
To re-assure my possible discovery, I went into my theatre archives in temporary history the next day, only there were no files. Fudge.
So, if anyone else has seen this mysterious golden Elite Minor, or thinks they might have once caught a glimpse of it, please respond. I am really hoping that I might have discovered something. Maybe it was a glitch or something, I dunno.
Cheers.
