Develop a reactionary nostalgia for a past you never actually lived through, with Classic-Vision! Instead of your beloved mercs, you'll be seeing the ugly mugs of the QuakeWorld Team Fortress classes for the duration of the Team Fortress 30th event. (Or forever, if you want.) (Or never, if you turn it off.)

Also featuring old-school sentry gun models, Quake-style gibs, and Team Fortress Classic's VOX announcer.

For an equally limited time, bare your old soul on four classic maps, ported up from previous Team Fortress games. In the interest of scholarship, these maps' alien environments and bizarre game rules have both been left near-wholly unchanged.

• Dustbowl Valley: Dustbowl was ported to Source by the Fortress Forever team well before Team Fortress 2 even released. Fittingly for a Source map, destructible wood and breakable windows are everywhere the eye can see.
• Epicenter: A bizarre take on Capture the Flag, even for its time. Pick up your own flag, carry it through a bombed-out military depot, and load it into a tank that's been impounded at the enemy team's roadblock.
• Gasworks: Originally a Half-Life multiplayer map, shamelessly reused once by Valve in 1999, and again by us just now. Charge up your armor (yes, really!) at HEV stations throughout this extremely vertical slice of Black Mesa.
• Canal Zone: Increase your team's score by holding more control points, which are naturally unlocked by giant holographic keys called Command Markers. The granddaddy of Territorial Control, and probably the inspiration for another, much-less-liked map set in a hydroelectric plant.
