It all looks pretty good. What site do you get all your info from? Not sure if i like the idea of having to unlock Frag grenades. If you unlock those what sort do you get as a standard or do you just not get any type of nade?

[MrBenis]

Active camo no longer cloaks vehicles that you're in. As for grenades, it is suspected that you'll have only 1 or 2, and need to unlock more.

Something like that.
