Klobbering Time is an Goldeneye: Source multiplayer achievement. The Agent state is awarded when the player gets 25 kills with the Klobb on any multiplayer match. Secret Agent state requires 75 kills and 00 Agent state 125.

It is one of the easiest achievements to earn. The best way to earn this achievement is to use the Klobb as often as possible. However, it is a weak weapon and it can be hard to rack up kills with, especially when used against more powerful weapons such as the Phantom. Keep on playing, and this achievement will be awarded eventually.
