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 certain events or Code Box.

Overview
The PowerSaw 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.
