I've noticed quite a few people have earned all of the city/property income, bank/vault and familia/squad income achievements. Why not make more of them to keep getting wealthy interesting?
i will have to say No For Zombie Slayers but for the other following like Mob Wars, Pirate Clan an Viking Clan Yes!!
This is unlikely to happen, the only new achievements you'll see for a while are for new locations once or twice a year and raids.
i am sure they might do this in the future but probably in the meantime, they have better stuff to do at the moment since they really dont listen to there Customers...but yea you know the drill lol
