Lead pipes can be found throughout the mall. The Lead Pipe is a good wepon when thrown, capable of killing a Zombie in one one hit. If used as a melee weapon, however, it will take several hits to kill a Zombie. When the Lead Pipe gets stuck in a Zombie you will see blood leaking out the other end of the Pipe. Its durability is increased with the Engineering book. To throw, hold the Left Trigger and press X.
