    How to upgrade the Vault? I have 50 War Bonds in my inventory but it doesnt show the button to upgrade the vault.

  • harry guyatt

    This is what they will do in the future

  • MrOverkill

    Does research facility 21 just need HQ 21? I thought it was a lot more than that

    • Hi, Yes it basically needs all the other buildings to be level 21 (other than the vault). I will get it updated

      • MrOverkill

        Gotcha thanks mate

  • AJAYYYY

    Kind of confused, how do you receive this? Or unlock to have option to get this?

    • HI, which building are you referring to? Thanks

  • MSMediacritic

    Just released. It’s called a vault.

    • Hi, as far as I know they haven’t released the upgrade in all States yet.

  • Kyle Kiser

    Is it possible to include the boost % of each level for death row

    • Sure – will try to get this up soon

  • Sean Kromer

    Would you be able to update the upgrade requirements on this page where “Market Place” is listed? I am putting together something that requires accurate information 🙂

    • Sure, will take a look

  • Jim Ben

    Ummm. I’ve played this game for 4 months and never seen the treasury… Never heard of it… I can’t find a picture of the building on google… I would almost call b.s. on that buildings existence if I had not gotten the war bonds to upgrade it in a gold gift crate. Has it been removed from gameplay or is there any info you could pass my way on the subject?

    • Hi Jim, yes it is a carry over from Game of War. Don’t know if they will ever release it, but the fact that War Bonds are in the game is big clue that it will come out at some point.

      • Matthew Kelich

        yeah its coming out they annouced it 2 days ago. :)) 100 percent

        • Great! Where did you see it announced? It’s not on the blog as far as I can see
