The “Gong Show” achievement in Left 4 Dead 2 is fairly easy to achieve. All you need to get the Gong Show achievement is a melee weapon and an adrenaline shot. You can only get this L4D2 achievement in the Dark Carnival campaign, 4th Level – “The Barns.” Near the start of “The Barns” is a strength test (the kind you’d hit with a hammer) – the sign nearby says “Are you as strong as Moustachio? Prove it!” Once you’re there, take your adrenaline shot and hit the pad on the lever with your melee weapon – but be ready. Once you ring the bell and gain the “Gong Show” achievement, you’ll alert a significant horde of zombies to your presence. Of course, by the you’ll already have the Gon Show achievement, which is what you were really after anyway.
