Emesis Blue is a 2023 Australian animated independent psychological horror fan film based on the online shooter video game Team Fortress 2. The film was produced entirely in Source Filmmaker, by the fan group Fortress Films, and released for free on YouTube on February 20, 2023. Emesis Blue bases many of its assets directly on those of the original game, following the nine playable mercenary characters on a fictionalized depiction of the 2Fort multiplayer map, but maintains a mature, surreal tone with an original narrative. At a total of one hour and 48 minutes, it received critical acclaim for its high production value and its length, both of which were said to be closer to those of a feature film than a typical Source Filmmaker production.[

A second Team Fortress film by the creators is "all but confirmed" under development as of 2024, currently titled Murder Inc.[1]
