you dont have to but to increase your mafias attacking power you should, eg- if your mafia is 10 then buy the best 10 guns and so on, the highest attacking weapon will be added to your collective mafia attacking power
you can buy them in New York.
It is good to have a lot of money in mafia wars to buy more guns,amo,knives, and other weapons
hired guns can never be removed. if you don't put your friend in top mafia, in wars you see 6 hired guns. it is a "extra add" if your mafia size is low.
none
Hired guns basically add one (or what is specified) to the total of the amount in your mafia. This can be used to take an extra weapon, armor, vehicle and animal into a fight, up to a total of 501 mafia
No, there is no such as buying clothes in Mafia... You can only do it in Mafia 2
There is no free mafia suit. You can buy a mafia costume from other players.
They are bought on the Godrather tab with reward points.
Mostly all of them.
You can't buy guns on YoVille. Besides, why would you want to buy guns on YoVille.
you can have as many items as you desire. the number of mafia does not affect how many items you may have but the number of mafia helps you in fights and robbing. the more mafia, the stronger you get in fights.
You buy it...
