bigballerbilly There is no reason for Plutonium to make a client. Plutonium is not here to make games free, it is here to make them better with things like dedicated server, mods, custom maps, glitches fixed, active moderators and better AC to keep out hackers. BO3 already has these things so there is no reason for a client to be made for it.
Edit:
Also making this clients takes a lot of time, and work. Be thankful that they have given you WAW, BO1, MW3, and BO2.
