After you buy a weapon, you should be able to buy upgrades such as extra ammo, more damage, faster reload, etc. The better the weapon, the more it costs to upgrade. You should be able to upgrade each weapon only 5 times for each thing you update. The mini gun shouldnt be able to get upgraded.

Some examples: 10+ damage for the Handgun: 500$       Faster reload for the AK-47: 2k
