Yes I think they are releasing land tiles 2 per day so far.
They have been loading up buildings to purchase in waves but need the land to place stuff.
Probably been planned a while as it doesn't generate a lot of income and costly to them. Subscriptions should be in place say £5 per month with new building and missions etc and this would pay for the game. Loads are willing to pay it.
I'm only level 675 i think and a lot of effort and purchases over the years and for it to end is quite bad as they have taken the money and basically running. Very unfair
