Achievement whores rejoice! Some francophone Left 4 Dead enthusiasts have created an achievement generator. This one offers three different achievement statuses, all the L4D achievement icons, or the capability to upload your own.
The generator produces two codes, one a standard URL, the other an embed code for all your too-cool-for-school forum posts. So, get out there and start achievin'!
