So I was looking around to find some info on what the hell this nemesis ribbon was all about; and found the info available not that clarifying. Looking around on the forum there was not that much on those Ribbons; while most medals are pretty clear on how to get them.
So I made the following small table (Chuy I used your stats images as they are more likely to stay).
Please if you could help with checking if it all seems to be correct or if you could provide the MVP / MVP 2 / MVP 3 bonus that would be cool.
Cheers,
R
edit: adjusted bonus points, amount of kills for the hand gun, kill streak, and nemesis ribbon
