My experience with KC so far is that it is just as much corner campers there as in TDM.
And score is still half compared to TDM until you pick tags so dont get scorestreaks any quicker.
Tried a bit of Search, much like earlier games. DOM is a bit hit and miss so far.
And the specialist is just annoying. I dont want to use the stun gun but it pops up all the time.
Might switch specialist though.
