I need a autobuy.
Do not know how to make someone can help me?

\Program Files\Valve\Steam\steamapps\STEAM_ID\counter-strike\cstrike

And find .txt file autobuy.
Go and edit it
This list of "buy aliases" is used by the AutoBuy system.
The system begins with the first alias in the list, and attempts to purchase it.
if a primary weapon is successfully purchased, all later primary weapon aliases are skipped.
Similarly, secondary weapon buy alias are skipped once a seconary weapon has been purchased.
You can customize this file to reflect your weapon and equipment preferences and priorities.

So down on the file,there's list of weapons, u edit it...
