Halo 3 achievement Problem 15000 pts on guerilla ach.?

[pantherbaseball14]

I tried getting the acheivement and i was playing with 2 other people and we got over 21,000 pts. It was on team scoring and all that, but do you have to do it individually, or do you have to get 15,000 pts for each person that is in your party.

you need the pts for indivudually, best if u play on heroic and have some off the skull activated to get a multiplyer, also to free for all scoring to see your indivual score

If you want the achievement, you personally need 15,000....individual scores are the ones that count....

me and my friends put it on normal and turned on all skulls except iron and blackeye and all 4 of us were able to get personal scores of 15,000
