Team Fortress 2
Valve’s genre-defining class-based shooter. Nineteen years old, still played daily by millions.
Welcome to the Cosmo strategy hub for Team Fortress 2. Valve’s sequel to the original Team Fortress launched October 10, 2007 as part of The Orange Box and pioneered the class-based shooter genre. Nine distinct classes with unique abilities, weapons, and tactical roles defined the gameplay; over the years, TF2 added a massive item economy, hats and cosmetics, competitive matchmaking, and a Workshop ecosystem. Despite occasional periods of minimal updates, TF2 remains one of Steam’s most-played games — 100,000+ concurrent peak players still regular. Everything below is vanilla, mechanics-only knowledge — the combat loop, the nine classes, weapons, game modes, maps, the item economy, competitive vs casual, Workshop, audio and settings, and pro tips.
