Team Fortress Classic (also known as Team Fortress 1.5) is a 1999 first-person shooter video game developed and released by Valve. The game pits two teams against each other in online multiplayer matches; each team member plays as one of nine classes, each with different skills. The scenarios include capture the flag (CTF), territorial control, and escorting a "VIP" player.
Based on the 1996 Quake modification known as just Team Fortress, Valve ported the game to the GoldSrc engine (used in Half-Life) as a way of promoting Half-Life's software development kit. Since the release of Team Fortress Classic, the game has undergone significant upgrades to the player models and game modes.
