Adrian Shepard from Opposing Force is an Ensemble Darkhorse Valve has been meaning to get back to including in the series. However in the interim, another series has sprung up with a lead also named Shepard. Cracking jokes about Adrian becoming Commander Shepard is fairly common.
Creating absurdly deformed faces in Garry's Mod by turning the facial muscle sliders way past where they were meant to go, or in combination with others they weren't meant to be combined with. Very popular in Garry's Mod based videos.
↑ One of the lines spoken by rebels to the player. They have some habits that the players find annoying.
↑From the introduction of Half-Life 2, part of the G-Man's monologue to Gordon Freeman. The original line is "Rise and shine, mister Freeman. Rise and... shine."
↑In the introductory level of Half-Life 2, a Combine officer stops you momentarily near a trash can, knocks over an empty can and orders you to throw it away. You can either oblige to the order or throw it at him, but either way you advance.
↑Natural Selection, a mod for Half Life, has an alien which can create webs; one hapless noob had his confused utterance immortalised. Often coupled with an image of Spider-Man, and used in any situation in which someone doesn't know how to operate something.
↑ Ellis often tells stories about his friend Keith, who has gained Memetic Badass status. Normally invokes Rochelle's reply of "Ellis, honey, can this wait?" or Nick's reply of "Ellis, is now the best time?"
↑ One of the Special Infected, the Witch will leave the player alone unless pissed off (which is very easy to do). When that happens the message "[player name] startled the witch" comes up.
↑ One of the locations in Left 4 Dead 2 is a Tunnel of Love. While in the tunnel, the characters in the game will refer to found weapons as "[weapon name] of love" rather than simply "[weapon name]."
↑ When Ellis uses adrenaline, he makes a rather memorable noise in reaction to the effect. Used similarly to Louis' affection for pills.
↑ One of the Special Infected, Chargers seem to have a nasty habit of turning up whenever a player does something overconfident or dickish. Thus, they gain the name "Karma Chargers". Also helps that one of their vocal grunts sound something along the lines of the aforementioned term.
↑Left 4 Dead's story is largely told through graffiti left on the walls by previous NPC survivors. One of them, calling himself Chicago Ted, left the above note in the final saferoom before the finale of "No Mercy."
↑ In L4D2's intro video, Nick teases an exhausted Coach that the rescue helicopter might be made of chocolate. "Chocolate Helicopters" happens to be the name of the music playing when he said that.
↑ A player-controlled Charger waits behind a door players have to open, then strikes as soon as they do so
↑ A Boomer spews on a player as a Smoker ties them up and dangles them in the air for the Common infected
↑Counter-Strike, while not the first game to reward headshots, was the first to add a meaty thwack! sound when pulling one off. Then CS became the most popular mod ever, cementing the idea that headshots were supposed to sound like that and here we are. FPS Doug is the Trope Namer.
↑A video where one player gets wedged between a half-open door and another player.
↑ The two sides in Counter-Strike are Terrorists and Counter-Terrorists. When one of them wins the round, the gruff announcer says "[Counter-]Terrorists Win". Someone animated the collapse of the World Trade Center in the Source engine, and used this as the punchline.
↑ Gabe Newell is the co-founder (and face) of Valve. Valve is notorious for Schedule Slip with all of their titles, and Half Life 2: Episode 3 has seen the worst of it, especially since they started the episodic content with the justification that they could release titles quicker. Many years later, and there's no evidence that they even started on Episode 3.
↑ More Gabe Newell fat jokes, emerging from the TF2 commentary. The original line is "...after nine years in development, hopefully it will be worth the wait."
↑ Boomers are a horribly obese Special Infected in the Left 4 Dead games. The comparison was inevitable.
↑ The standard answer for when anybody asks when the next Valve-related product is going to be released, related to both Schedule Slip and Vaporware. Half Life 2: Episode 3's release date is apparently pegged as "Coincident with the Rapture."
↑ Something of a meme on boards such as Steam Forums and Facepunch.
↑A meme resulting from Gabe Newell's email address, email@example.com, said at the end of the first commentary piece in Team Fortress 2's commentary maps. It is pronounced "Gabe N.", which sounds like "Gay Ben", and is sometimes used in the latter context.
↑For one of the Portal 2 commentary nodes, instead of pronouncing his name on the email address he spelled it out (maybe because of the above?).
↑Even though they're juggling more than half a dozen properties at this point, none of the games have received a proper third installment. And which episode of Half-Life 2 is being delayed absurdly long, even by Valve standards? Episode Three, of course.
