The Fairgrounds

The Fairgrounds is the second chapter in Left 4 Dead 2 ' s, Dark Carnival campaign. It was first revealed at the Penny Arcade Expo and again in Tokyo Game Show '09. The chapter contains a Gauntlet Crescendo that requires the Survivors to open a gate by switching on a power box, which also activates a nearby carousel that attracts hordes of Infected until it is shut down. The safe room at the end of the level is in the Tunnel Of Love.

In this part you can find Gnome Chompski to get the 'Guardin' Gnome' achievement. Near the beginning you will find a shooting gallery. Everyone can play. Press the button and it will start.
 * Shoot burglars with bags of peanuts for points.
 * Shoot two burglars of the same color for a bonus.
 * Shoot Moustachio for even more points.
 * Don't shoot Lil' Peanut.

If you manage to get 750 points, Gnome Chompski will be released. You carry him like a gas canister. You can only shove with him and he covers most of the right part of your screen. He can't be destroyed and you can drop him now and then when a horde is coming. It doesn't matter who carries him, if he is safely taken to the end of the campaign, everyone, even if they have been killed in the finale, will get the achievement. A good strategy to do when you're in the peanut gallery is to throw a Molotov at the back row. It takes out the back instantly so then all you have to worry about is the front row. But the bad thing is that i will hit the peanut too.

Trivia

 * The actual name of this chapter is Fairground, not "The Fairgrounds".
 * At the start of the level is a Lil' Peanut sign that breaks apart whens shot.
 * Because of this, Survivor and even Infected players seem to impulsively attack it. Unfortunately, this habit often carries into the shooting gallery, where the peanut is a penalty, making it much harder to win the gnome.
 * Occasionally, Infected Hunter bots have been seen jumping to the Lil' Peanut sign, attacking it, and then retreating back to cover.
