add a system that we can buy the weapons by typing the amount of ammo we want to buy for that particular weapon instead of clicking the button thousand times .add in both pd and ammo . also to stop the mismatch of currency , the number which you can type will be multiple of the weapon's one lot .example - in shotgun , the amount given is per 10 ammo . so the amount of ammo you can type should be a multiple of 10 or the system will not accept it . i think this will save a lot of time .
