Shotgun (Evolution)

Throughout the development of Half-Life and it's sequel, Gordon's iconic shotgun changed looks quite a lot. Despite this, it's always retained it's basic look as an off-brand SPAS-12.

Part 1: Half-Life

Version 1: Late Alpha

Blue/grey shotgun, bare red hands

Version 2: Early Beta

Blue/grey shotgun, gloved red hands

Version 3: Late Beta

Grey/brown shotgun, gloved orange hands

Version 4: Day One

Black shotgun, updated mesh, gloved orange hands

Version 5: Retail

Same as before, but with slight mesh changes

Version 6: Gearbox

For Gearbox Software's Half-Life expansions Opposing Force and Blue Shift, they didn't alter the Shotgun as much as they did the Glock or MP5. Here they only re-animated the weapon, but kept it close to the original, unlike the MP5. The model was not changed aside from Adrian or Barney's hands being added in place of Gordon's.
