I don't have the game here, right now...
I was just done spoiling my ass with p0rtal and ep? vids, but it all gave me the overall impression that barney somehow managed to walk off the edge of the earth, or did he have some minor cameo appearance in the middle of the game that managed to slip past me??

No spoiler tag, no cookies for you.(or should is say nussecken!?)
Seriously though,why do such a stupid thing and spoil yourself the experience?
