Can I have an instafrag match in Counter Strike: Source?

Question

Is it possible in counter strike source to increase weapon-damage (in a bot-match) so that everyone gets one-shot kills?

Answer 1

You can't do this client sided, or at least, legally. A client side modification would be a hack and in the event of attempting to do this you will likely get VAC'd.

You need a server side plugin to do this for you. Whether you create a local game on your computer or connect to one online, you are still playing in a server environment. When you start a game on your computer it creates a server with your local IP and connects you to it.

The easiest way for you do do this for yourself playing with bots would be to install Sourcemod in your cstrike folder. It's in steam>steamapps>yourname>counter strike source>cstrike

There you will create a addons folder, inwhich you will put sourcemod, metamod, metamod.vdf, etc.

After download this plugin and place it in the plugins folder. [CSS] Weapon Mod

Set up the cvars/configuration files to your needs. It looks like you're looking for:

genericdamage -- min value 0.0, max value 1000.0 -- Modifies damage done to the generic hitgroup. 0.0 stops the damage. This hitgroup is used by knife, grenade explosion and flashbang/smoke projectile physics damage.    
headdamage -- min value 0.0, max value 1000.0 -- Modifies damage done to the head hitgroup. 0.0 stops the damage.    
chestdamage -- min value 0.0, max value 1000.0 -- Modifies damage done to the chest hitgroup. 0.0 stops the damage.    
stomachdamage -- min value 0.0, max value 1000.0 -- Modifies damage done to the stomach hitgroup. 0.0 stops the damage.    
armdamage -- min value 0.0, max value 1000.0 -- Modifies damage done to both arm hitgroups. 0.0 stops the damage.    
legdamage -- min value 0.0, max value 1000.0 -- Modifies damage done to both leg hitgroups. 0.0 stops the damage.

Then once you create a local server the plugin will load and you'll have your damage.

You should look at a headshot only script. I think there will be something in it about this since headshots do way more damage than they are supposed to do.
