Use this for a rockin' good time! -in-game description
The Power-Infused Gary Autobiography is an item and weapon found only in the Apocalypse Weekend half of both AWP and Postal 2 Complete. However, it is only available in Enhanced Mode in P2C. When picked up, it will be in the inventory, but once it is activated, the Dude's weapon changes to Gary's head and there is a Gary head with a three next to the Dude's health. The Dude's vision also changes to the hallucination filter. The effect ends when enemies destroy the Gary heads surrounding him. They can be destroyed if they are shot by the enemy or if they touch an enemy. The Dude still takes ordinary damage while being unable to use any other weapon.
Primary fire launches a Gary head straight forward while secondary fire launches a homing head. The Dude does not lose any heads for firing them. The Gary head basically acts as a missile, primary fire exploding wherever it lands or touches before landing, and the homing head exploding either when it reaches its target, when it touches another living being which intercepts the head, or if the head simply cannot reach its target.
The player may have as many as 9 Gary heads orbiting him at any given time, which can be achieved by using 3 books one after the other.
