The crowbar, as seen in Black Mesa. Texture made by VertThrasher.

Overview

The crowbar is the signature weapon of Gordon Freeman in the Half-Life series. It is a fairly lightweight tool used for prying objects apart, and also a proficient melee weapon in the right hands.

In Half-Life and Black Mesa it is found shortly after the Resonance Cascade in the chapter Unforeseen Consequences.

Primary Function

Swing the crowbar.

Trivia

• The Crowbar will not feature a secondary function for a more powerful attack. This would ruin the challenge intended for the beginning chapters. [1]
• The Skin of the Crowbar is changed because Gordon found it as it was newer and less used.

Redesign History

The crowbar model in Black Mesa is the same used in Half-Life 2. However, it has custom skin and animations. [2]
