2) The numbers found in the drop down box are the Upgrades you buy from the Black Market guy in Concordia. If you have only upgraded Assualt ammo once, then it will say 1, if twice then 2, simple as that.

5 – Upgrade for assault rifles
5 – Upgrade for pistols
5 – Upgrade for rocket launchers
5 – Upgrade for shotguns
5 – Upgrade for SMGs
5 – Upgrade for sniper rifles
5 – Upgrade for number of grenades
5 – Upgrade for backpack space
5 – Upgrade for bank space
5 – Upgrade for laser weapons

3) To get unlimited ammo, paste the following in the ‘BlackMarketUpgrades’ drop down box. (The zeros will correspond to the backpack and bank space, see above to note which numbers correspond to which upgrade.)

I suggest setting all values to 99, but you can of course go higher. 99 will give you roughly 15,000 ammo in Assault/Shotgun/Pistol, 103 grenades, and 300 rockets.

So after you were done it'd look like this in the BlackMarketUpgrades Tab (Copy & Paste this in your Black Market Upgrades)

99
