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.

Campaign
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 possible strategy for the shooting gallery would be to throw a Molotov into the back row, destroying all targets back their. The only downside is that the Molotov will destroy the Lil' Peanut targets 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 when 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.
