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 its new in-house engine, Source. Following the announcement, Valve released no news on the game for six years. Walker and Cook worked on various other Valve projects; Walker was project lead on Half-Life 2: Episode One and Cook worked on Valve's content distribution platform Steam. 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.

The game debuted with the Source engine's new dynamic lighting, shadowing and soft particle technologies alongside Half-Life 2: Episode Two. It was the first game to implement the Source engine's new Facial Animation 3 features. Valve abandoned the realistic style when it became impossible to reconcile it with the unrealistic gameplay, with opposing armies having constructed elaborate bases directly next to each other. The Commander class was abandoned as other players would simply refuse to follow their orders. Valve designed each character, team, and equipped weapon to be visually distinct, even at range; for example, the coloring draws attention to the chest area, bringing focus on the equipped weapon. The voices for each of the classes were based on imagining what people from the 1960s would expect the classes to have sounded like, according to writer Chet Faliszek. The map design
