I got the game today just watched the video it hasn't ruined anything for me, seems it's just a little Easter egg.
It's only like about a minute more than the story you sit through at the start.
Have you watched any videos on it, I saw one the other day it says MP and single are separate so stuff gained in MP doesn't transfer over to single player.
Yeh I do kind of wish I hadn't bothered but at the time I didn't realise there were different versions, same deal with the Dr. Nope. Can't see me ever using that now either.
Just ran the prologue like most new games it looks complicated but looks great and as long as I can keep shooting and stabbing stuff without too much frustrations all should be OK.
I thought about it till I found out any rep resets so I don't have nearly enough time to grind it out, I will be interested in seeing roughly how long it takes if any of you do it.
