Forum:Rivalry

In Call of Duty 4 on PS3, ive been trying to get the "Rivalry" Challange under the "Humiliation" section. It says to kill one person atleast 5 times in a single match. Ive counted up to 8 kills on a single person in a single match, but it never said i achieved or gave me the XP. Please help. Ive been tyring for a few days now. a D0R1T0 (#1 Alexander Ovechkin fan...Go Caps go!) 04:53, September 20, 2009 (UTC)
