Baseball Bat

"That's a home run!"

Trivia

 * In the first Left 4 Dead 2 trailer, the attack sound uses the same audio attack from Team Fortress 2, a metal ding sound. The sound files have been changed to fit the wooden properties of the bat.
 * The Baseball Bat is only available to players who pre-ordered Left 4 Dead 2, meaning Valve may have to tweak some achievements so some still work whether they have the baseball bat or not; however, as playing with a player who did preorder it gives you access to it, you might still be able to get said achievements.
