Money and Weapons

To get 16000$ which is the max, sv_cheats must be on. So type in the following in your console:

sv_cheats 1

This will enable the cheats. After activating you must restart the level/map. Then type in impuse 101 in your console and you will have 16000 dollars!

The other code is for the weapons. I dont want to take all the time to explain all the weapon names because if you already play Counter-Strike alot you should know the weapons/weapon code names. to get the weapons you must have the cheats activated once again sv_cheats 1.

Now type the following in your console

give weapon_< -weapon name here- >
