That is actually a really good idea. We know about a SMART one and a medic one has anyone heard about the other 2 challenges.
No, but I heard they're also designed as tutorials. I think that's a pretty cool idea, incorporating the weapon/attachment reward system with the tutorials, as well as having more advanced versions. Tutorials are usually designed to be easy, and are generally extremely boring, so it's a nice change of pace to have an easy, medium, and hard version of each tutorial, as well as weapon, attachment, and achievement unlocks tied to them. Sounds like a good system, and a good incentive to make people actually want to play the tutorials. Plus
challenge sounds so much more badass than
tutorial.
