Ripper

PowerSaw is a chainsaw that is categorized in the equipment category (slot 8 in the buy menu) and is used as a primary weapon slot. It is only obtainable from Code Box.

Overview
The chainsaw is capable to do extreme damage in a short time. Unlike any other melee weapon, the Powersaw uses 200 liters of gasoline as it's 'ammunition'. Once it runs out, only the secondary fire mode can be used. The secondary fire mode makes a horizontal slash and inflicts high knockback against multiple targets while not using up any gasoline. However, it is only effective at close range.

Trivia

 * This is the first melee weapon that is categorized as an equipment and has a magazine capacity, though in-game it uses gasoline.
 * There is a "POWERSAW" print on the chainsaw's guide bar & "SAW" on the front of the chainsaw.
 * The reload animation is similar to "turning on" the Powersaw.
 * This is the third weapon that is lighter than the knife after Steyr Scout and Tempest.
 * Once you ran out of gasoline, the slash attack will use a different sound.
 * It is highly recommended for destroying barrels and killing zombies on Pursuit and Survival in Zombie Scenario modes.
 * Oddly in Zombie: The Union, the weapon will be colored according to the team which the user plays in, instead of the hands.
 * Sometimes the secondary attack doesn't knock zombies away.
