Is Team Fortress 2 available on mobile devices? Not officially. TF2 has never released a native mobile client; Valve’s official releases place the game on PC and Mac via Steam, with Linux support as well. The Steam store lists Windows, macOS, and Linux as supported platforms, confirming there is no official Android or iPhone version. The game has remained a free-to-play PC title since 2011.

However, you can play TF2 on mobile by streaming from a PC using Valve's Steam Link app. Steam Link lets you run Steam games on iOS and Android when your PC is on the same local network; you can pair a controller and play remotely. The iOS Steam Link app is available in the App Store, and Steam's mobile page confirms Steam Link as the mobile path.
