Since December 2017 the game of CKS has had no one from glu updating or administering it. The game was transferred from the studio in Moscow to their subsidery company in Hyderabad and was supposed to become active again in April. (Not happened )
Any enquiries to glu will only result in their standard reply.. Which does not answer the question " is this game dead "
Do not waste money on this game! Until glu starts to get their act together.
