Unlocking zero chill challenge have EA account still locked in challenges in madden...

You’re just an EA hater you haven’t even played madden. Go play Brain Challenge you need it!

This happens to me a lot on final kill cam challenges. I got the flawless one with only 5 kills but I don't remember what level I was when it happened. I think you may have to be at a certain level to unlock certain achievements or perhaps there's prerequisite
challenges you have to unlock before you get to those because I noticed a lot of my challenges are still locked and won't tell me why or what I need to do to unlock them. 'Tis a pain indeed

I was talking to my friend about this earlier and this is what I think:

Challenges are not unlocked for completing the previous level. For Example I was using the MSBS earlier and got 120 kills. Now I know that there are two more badges but as far as I could tell I was making no further process and my challenge in the weapon
operation challenges was still showing level 1 challenges complete 120/120.

But you can spend 1 token to unlock new challenges and speaking to my friend he told me that he had unlocked new challenges earlier today and that he had the 2nd level of the Scavenger challenge complete.

So my advice would be to try unlock the challenges in the operations menu to see if you get your chrome barrel attachment challenge appear.

I personally don't like the way that Infinity Ward appears to have locked the challenges behind these time limits/unlock tokens rather than the old way of certain sets of challenges opening up at new levels but if this is the way it works then so be it.

It just seems to make the leveling so slow as you aren't automatically unlocking the next level when you are doing certain challenges and thus earning less XP as the normal challenges don't unlock in the same way as I'm used to.

I just bought Sine Mora EX and Fe. The first looks like it'll be quite the challenge unlocking all of the achievements, and the latter looks pretty chill and it has a really good discount.
