Using +attack3, you can shoot grenades out of the end of certain guns! You can modify these grenades in any way you like, change their speed, magnitude, radius, the ammount you can hold and what guns fire them. Very fun to blow the crap out of groups of enemies. And you can use them while firing
1. Extract to your cstrike folder. 2. Add es_load nadelauncher to your autoexec.cfg. 3. Restart server.
