Attack mod should kind of mirror MCC V2 in my view, With Hospitalise, Mug and Leave options. One to add time to hospital time, one to mug other players' money that they have on hand, and the other to gain EXP by attacking players at a higher level than them in order to level. Turn based attack system with a player's stats and equipment(weapons and armour) being taken into account in determining a successful attack. I would imagine a lot additions like a hospital, and other features will need to amended for it to work like this...
