The player can join one of two teams, RED or BLU, and choose one of 9 character classes to battle in game modes such as capture the flag and king of the hill. Development of the game was led by John Cook and Robin Walker, the developers of the original Team Fortress mod. Team Fortress 2 was first announced in 1998 under the name Team Fortress 2: Brotherhood of Arms. Initially, the game had more realistic, militaristic visuals and gameplay, but this changed over the protracted nine-year development. After Valve released no information for six years, Team Fortress 2 regularly featured in Wired News’ annual vaporware list among other ignominies.3 The finished Team Fortress 2 has cartoon-like visuals influenced by the art of J. C. Leyendecker, Dean Cornwell, and Norman Rockwell,4 and uses Valve’s Source game engine.
