Certain gameplay mechanics are also more refined, simplifying all class loadouts while removing reliance on grenades and bunny hopping.
Unlike the previous installment, Team Fortress 2 sports a cartoony CGI appearance influenced by both mid-twentieth-century Americana and 1960's spytech (after several lengthy development cycles involving realistic modern-military combat and futuristic alien invasions). The long-awaited sequel to the original Quake modification 'Team Fortress' (and its standalone update, Team Fortress Classic), players join one of two teams (RED and BLU) as one of nine playable classes, each with their own unique traits and assortment of gear, as they fight over a variety of objectives including capturing briefcases, holding 'control points', and pushing large warheads on rail carts. The Steam version of the game became free-to-play on June 23, 2011. It was also released as part of The Orange Box (for the Xbox 360, PlayStation 3, and PC), was later re-released as a standalone retail package for the PC (on April 8, 2008), and was later updated for compatibility with Mac (on June 10, 2010) and Linux (on November 6, 2012) on Steam. Team Fortress 2 is a multiplayer team-based first-person shooter developed and published by Valve for the PC (via Steam) on October 10, 2007.
