SPECACT is the final kit added to the game. Which is for Recon. Assault. Engi. and Medic. All four of these final weapons are remade and have given a different camo. Not only that but it is its own weapon making you able to re medal the final four weapons again. I really hope they will be able to put this in. Since they are having trouble with the steam conversion
SPECACT is one of the reasons steam keeps refusing this patch. I'm pretty sure they are trying to get it working, but I'm pretty sure SPECACT isn't going to be coming out to PC for a while.
