[SOLUTION]Warhammer 40000: Space Marine dlc giveaway (puzzle) "Quick"

So, giveaway ended, 1 solver but 0 entries...
Answer should be pretty obvious by now but I'm gonna post it here anyway.

1.The right option was a)MFd ( as a whole)

2.insert it after the question mark in the url of the webpage. Like so http://trip.coresv.com/index.cgi?a)MFd

3.Find the comma, [ a)MFd, ] /tCX5e/Igl Go down --This line has the comma. Notice the 5 character code (tCX5e)

4.My X clue---> X becomes lowercase---x

5.Giveaway code completed tCx5e

EDIT: Come on...big clue in the comments...

The code is hidden deep within TGCP (Trip generation concept ****)
You have 3 options...

a)MFd
b)KD4
d)FO3

PS. I'm looking for a comma, also if you happen to see my X tell her to get low.
PPS. The answers comes AFTER the question mark.
5char

Less than 1 hour before giveaway begins and it will last one hour. Good luck.

Last TIP: you're on the right way if you can find index and Suzan, I expect you to solve this now I'll be back when the giveaway ends.

Bonus TIP: options as a Whole --"Whole", whole,whole....wonder why there's a,b,d?
