The Baseball Bat is a zero-range weapon which can propel the victim over a great distance. It does 30 damage by itself, but is generally used when a kill can be made by batting the enemy into the water.
Tactics
To achieve the greatest distance, the Baseball Bat should be used at 45 degrees. You can set this angle easily by selecting Kamikaze.
Tricks and glitches
It is possible to fire the Baseball Bat vertically (or any other angle). With fall damage enabled and at default power, it does 43 damage when pointed completely downwards, and a maximum of 42 damage when pointed completely upwards.
