The Evolution of Classic Textures in Half-Life: The Headcrab's Journey

Half-Life, one of the most iconic video games of all time, has undergone numerous changes and updates since its release. One of the most notable transformations is that of the classic headcrab, which initially made an appearance in the game's first installment but eventually returned to Half-Life 2 with some significant modifications.

In Half-Life 1, the classic headcrab was a distinct entity with its own model and texture. However, it did not last long, and even before the introduction of the first set of zombie models, the classic headcrab had already made its way back into Half-Life 2. This was largely due to the transition from old zombie models to fat zombie models, which led to the headcrab's model being replaced by its own unique one.

A closer examination of the Brickbat (BB) headcrab model reveals that it reuses two textures from Half-Life 1's classic headcrab, albeit in a modified state. The polygon count suggests that this model was developed much earlier than even the later fast headcrab model. This raises questions about the timeline of the headcrab's development.

Concept art dated back to 2001 provides further insight into the evolution of the classic headcrab. It depicts a fast headcrab on top of a zombie with textures that closely resemble those of the 'old' zombies, featuring rips near the elbows and knees. This suggests that the classic headcrab's model would have initially used an earlier-completed composite-sheet fast headcrab model before moving to Version 2.

The texture sheet for the fast headcrab also appears in the classic headcrab's texture folder with some coloring differences between the two. Moreover, all three of the 'old' headcrab zombies' textures use headcrabs that are more akin to the fast headcrab, sharing similarities with its textures (particularly on the side).

The Brickbat model for the headcrab is shaped identically to the final fast headcrab, featuring thin, long legs and a smaller main body. Both the model texture paths and the models themselves refer to the fast headcrab as 'Headcrab' and the normal headcrab as 'headcrab_classic'. Several factors suggest that the fast headcrab originally replaced the classic-style headcrab.

In conclusion, the evolution of the classic textures in Half-Life is a fascinating topic that provides insight into the game's development process. The headcrab's journey from its initial appearance in Half-Life 1 to its return in Half-Life 2 with significant modifications highlights the constant changes and refinements made by the developers.
