I was looking for but that is not I want, I want to tape it infinite ammo, for example: 30/infinite

mp_infammo 1

How to use?

If you are admin of server then open console.
~ is default console key
after that type in mp_infammo 1 and you're done.

If you're using remote control password then
Open console and type in your rcon password
E.g. rcon_pw banana
After that type in the same thing but use "rcon before it.
E.g. rcon_pw banana
rcon mp_infammo 1

Not really. Its set to "CONKEY" (Not sure what is that)
I think that its related to German keyboard or whatever. Just set it from the controls tab in options.

It's no special German key. I just called it that way because it's something different depending on they keyboard layout.

In Germany it is the key for ^ and ° (it's below ESC on German keyboards). In other countries it seems to be ~ or something entirely different.

I know. but i click it does not show? why?

@ DC: I see. Thanks for this little piece of information.

conkey seems to be a macro that stands for ~ or ^ or whatever key is in the same position, but as far as i know it doesnt work. i just set it to ~ in key setup

For my computer CONKEY is "|" or "\" under "Backspace". When i press it, it works.

In case you can't find the right key:
Just enter the command in the chat but add a slash in front of it! I mean enter the following in the chat:
/mp_infammo 1

It does exactly the same thing without opening the console.
