To use the SndDrv.dll method you go in your crossfire folder, and then you paste the hack in there. Be aware to back up the SndDrv file that already exists in there... Meaning copy and paste the SndDrv.dll somewhere else.
After, in your CF Folder, run cf_patcher.exe, and the hack will inject automatically.
And we don't have any aimbots released at the moment. Wait for a new release.
