The first version of Team Fortress, an add-on for Quake, was released on August 24, 1996. It was originally written because the authors wanted a first-person perspective, team strategy game for LAN competitions. Version 1 .0 only included the Scout, Sniper, Soldier, Demolitions Man and Medic classes and did not support any map entities.
