Complete at least 2 goals in a sam challange
there are only 2 challenges and I need 4 and I've already done 2/4 EA Give me back my tix
Ideas
If you play the missions, more slam mission will appear as you unlock and level. It's not a game issue, it's a skill issue. I did the 4 just fine! Also, you need to solo them, so that you complete all the achievements yourself. Or party with someone that hasn't done all the slams and that other person needs to be party leader as well. Good luck
You have 4 because you're a lower level. I'm 10,10,10. They only gave 2 new slams challenges, the other 6 that were previously done won't register. So it's far from a skill issue, if anything it's cause we are too skilled and being penalized for it.
I made a 2nd acct 2 days ago and it didn't have a problem with 4 slam challenges because it was a new acct and there were 12 slams to be done.
Get your skills up low level noob!
