i spent hours and lot of coins on the challenge but the game disconnected every game and the servers were down all the time. so i barely had time to play as i also have a job and if had time or the game worked but disconnected every game or the game didnt work at all. so i couldnt get acuna shapeshifter which in my opinion the best cdm in game. i love the game but i have done all the objective except 2 wins because i just couldnt do it with all the servers and disconnection so i dont have him now.
