Immolator

The Immolator is a weapon cut from Half-Life 2. It can be found in the playable Half Life 2 Beta. It was intended to be used by Cremators to clean the City 17 streets, then be acquired by the player.

Overview
It was to function similarly to the human-designed flamethrower except that its plasma or burning liquid also possessed corrosive properties, allowing it to nearly "eat away" organic matter.

Behind the scenes
As seen in the playable Half Life 2 Beta, it was at some point possible for the player to assault Striders and take their gun. Noclipping to the Strider's head, then pressing the Use key results in the player seeing through the creature's eyes. At that point the only thing to do to free oneself is to kill the creature, for instance with the RPG (as the only way to kill a Strider in the playable Half-Life 2 Beta is by standing inside its head), or reload the game. When killing it, the Strider collapses, releasing the player. At that point, the red ERROR model appears. When walking through it, the player acquires the Immolator. This suggests the Immolator acts here as a placeholder for the Strider's warp cannon, and that resuing it was at some point considered, role that the Combine Guard Gun was already filling. As a side note, the Immolator worldmodel exists and should appear instead of the ERROR model.

Trivia

 * In the playable Half-Life 2 Beta, the viewmodel texture incorrectly uses the hands texture. This also happens with the Combine Guard Gun
