@mr_zahi its not map... its script. add it to YOU-CS2D-FOLDER/sys/lua and write in server.lua dofile("sys/lua/shop.lua"). now in game press F2, F3 or F4 and buy any item in shop
"You haven't got enough money"
(or "You do not have enough money")
"You've bought a flamethrower"
You could make an anti-noob system for it that marks the noobs by their actions and if they try to buy something it says:
"F*ck off, you don't have enough brains to buy this!"
