The Fight or Flight update, was the second major update for Team Fortress 2 Classic. True to its namesake, it focused on content related to mobility, as well as several weapons and maps. Its flagship feature is the Jump Pad, an Engineer building that allows taking to the skies. The Anti-Aircraft Cannon was designed for Heavy to swat enemies out of the air, while the Twin Barrel affords Pyro greater mobility. The Brick gives Scout a hard-hitting projectile, while the Heavy gains Chekhov's Punch and the Pyro gains the Harvester - both weapons that store critical hits for later. Finally, L'escampette gives the Spy an alternate watch, allowing for easier escapes. The update also introduces the Arena map Floodgate, the Four-Team King of the Hill map Frigid, the Payload map Jinn, the Four-Team Medieval Mode map Krepost, and the new Territorial Domination game mode with the map Caper.
