User:Thunder Dash/Proto:Half-Life

The September, 1997 prototype of Half-Life is radically different from the final game, from over a year before the game's release.

Heads-Up Display
Even though it's disabled by default, the prototype has a HUD. It's completely different from the one present in the final, and only seems to be partially programmed.

The bar in the bottom left is the player's health. Other than that, none of the HUD's components seem to be implemented yet.

Something to note is that the HUD doesn't render properly in OpenGL mode. If the game is run in Software mode (which can be done by setting your desktop's color depth to 16-bit), the transparency renders correctly. It functions the same way regardless of the render mode used.
