Soldier (Evolution)
From Valve Cut Content
Through the 24 year existence of Team Fortress, the Soldier has prevailed as one of the most popular classes, along with Sniper, the Demolitons Man & the Heavy Weapons Guy. Let's take a look at the evolution of his design.
Version 1: QuakeWorld Team Fortress
In QuakeWorld Team Fortress, the Soldier appears to wear a chestplate over a camoflagued jumpsuit. He wears a helmet with glasses and carries the Rocket Launcher in thirdperson.
Version 2: Team Fortress Classic Beta
This variant of the TFC Soldier was only seen in a few screenshots before release, however, it more resembled the QWTF Soldier than release TFC Soldier, with the notable presence of a helmet, goggles, and a team coloured jumpsuit.
