Wikipedia: The original Team Fortress was developed by Robin Walker and John Cook as a free mod for the 1996 PC game Quake. In 1998, Walker and Cook were employed by Valve Corporation, which had just released its first game, Half-Life. They and Valve began developing Team Fortress 2 as a standalone retail game using Valve's GoldSrc engine. In 1999, Valve released Team Fortress Classic, a port of the original Team Fortress, as a free Half-Life mod. Team Fortress Classic was developed using the publicly available Half-Life software development kit as an example to the community and industry of its flexibility.

In contrast to the original Team Fortress, Valve originally planned Team Fortress 2 to have a modern war aesthetic. It would feature a command hierarchy including a Commander class, parachute drops over enemy territory, networked voice communication, and numerous other innovations. The Commander class played similarly to a real-time strategy game, with the player viewing the game from a bird's-eye perspective and issuing orders to players and AI-controlled soldiers.

Team Fortress 2 was first shown at E3 1999, where Valve showcased new technologies including parametric animation, which blended animations for smoother, more lifelike movement, and Intel's multi-resolution mesh technology, which dynamically reduced the detail of distant on-screen elements to improve performance. The game earned several awards including Best Online Game and Best Action Game.

In mid-2000, Valve announced that Team Fortress 2 had been delayed for a second time. They attributed the delay to development switching to an in-house engine, the Source engine. Following the announcement, Valve stopped releasing information about Team Fortress 2 and the game entered six years of silent development. Walker and Cook worked on various other Valve projects; Walker was project lead on Half-Life 2: Episode One and Cook became a Steam developer. Team Fortress 2 became a prominent example of vaporware, a long-anticipated game that had seen years of development, and was often mentioned alongside another much-delayed game, Duke Nukem Forever. Walker later stated that Valve built "three to four different games" before settling on their final design. Shortly before the release of Half-Life 2 in 2004, Valve's marketing director Doug Lombardi confirmed that Team Fortress 2 was still in development. Valve reintroduced Team Fortress 2 at the July 2006 EA Summer Showcase event with a drastically different visual design.
