The daily challenges, those are the bottom three bars on my screen when I play right? Below Rank/CR/Milpoints right?
I haven't tried for those yet at all.
I just figured out that the more CR MAX you have, the faster each individual point replenishes. I'm just gonna throw a ton of my points into CR MAX and I'll be able to get more done. I'm working on reducing insurgency right now. Those Intel missions kick ass too!
