I'm not aware of a way to find that out. You could try emailing the devs I guess... I'm not sure they keep track of that kind of thing.
Any with pots. You can assassinate any EB with those spy stats but would need attack pots for anything haunting and above.
I had 16 bill in allies with 800k attack stats,than upgraded and have 1mill attack stats,do I need to buy more allies or how come the cash I get per attack didn't increase?
How come the new achievements haven't appeared on my latest achievements? Yes, I hav earned 2, but I want them on display
@angel I'm able to see your's... (btw you only have one) and try restarting the all reinstalling or If all else fails email the devs
To get them just do the action for the achievement. For instance, steal someone to get steal achievement. If that doesn't work. Email.
