Interesting Facts (2)
- #001
Quentin Tarantino counts Half-Life among his favourite computer games and has said he'd like to turn it into a film one day.

There are just four types (four faces) of scientists and one type of security guard in the game.
Production Story (24)
- #003
In the original plan, security guards became your enemies the moment the resonance cascade hit; Barney almost didn't owe you that beer.
- #004
Half-Life: Blue Shift (2001) was originally meant as a bonus exclusive to the Sega Dreamcast version of Half-Life. When that version was canceled because of poor sales and the impending demise of the Dreamcast console, developers Valve and Sierra released the Blue Shift add-on for PC instead.
- #005
Rather than full lines of dialogue, the Black Mesa PA system uses single words, letting level designers assemble announcements dynamically. Most of the words never appear in the game proper; they exist so that independent level designers can build realistic-sounding PA messages for their levels instead of using the default ones.
- #006
As Half-Life grew, Valve cancelled Prospero, its fantasy role-playing game, and moved the Prospero team onto Half-Life.
- #007
During development Half-Life went by the working title Quiver, after the Arrowhead military base in The Mist.
- #008
The name Half-Life was chosen because it evoked the game's theme, avoided cliché and came with a visual symbol: the Greek letter λ (lower-case lambda), the decay constant in the half-life equation.
- #009
Designer Harry Teasley said Doom was a big influence on Half-Life and that the team wanted the game to "scare you like Doom did". Designer Brett Johnson said the level design borrowed environments from the manga series Akira, while Newell named the immersive first-person experience of Ultima Underworld, the horror of Resident Evil 2 and the game design of Super Mario 64 as influences.
- #010
Valve struggled to find a publisher for Half-Life, since much of the industry thought the game too ambitious for a first-time developer.
- #011
Under the deal, Sierra gave Valve an advance of roughly $1 million in exchange for 30% of revenue and full ownership of the intellectual property; Newell and Harrington paid for the rest of development themselves.
- #012
Valve first showed Half-Life in early 1997, and it went down well at that year's E3, where the studio demonstrated its animation and artificial intelligence, including novel features like fear and pack behavior.
- #013
By September 1997 Valve had built some innovative ideas into Half-Life's weapons, enemies and level design, but the team felt the game wasn't fun and lacked a cohesive design.
- #014
Sierra wouldn't put up more money, so Newell took out a loan to pay for the extra development that reworked Half-Life and pushed its release date back.
- #015
Valve set a small team to build a prototype level containing every element of Half-Life, then spent a month refining it. Designer Ken Birdwell called it "Die Hard meets Evil Dead", and when the rest of the team played it they agreed to use it as the baseline.
- #016
The Half-Life team came up with three theories about why the prototype level was fun; the first was that lots of interesting things happened in it, all triggered by the player rather than a timer, so the player set the pace.
- #017
The second theory about Half-Life's prototype level was that it reacted to whatever the player did, even something as small as a decal on a wall texture marking a bullet impact.
- #018
The third theory about Half-Life's prototype level was that it warned the player of danger ahead so they could avoid it, instead of killing them with no warning.
- #019
Unable to find a single game designer to carry a unified design forward, Valve formed a group it called the "cabal" to design Half-Life.
- #020
The cabal started with six people drawn from every department at Valve, and for about six months they met four days a week in six-hour sessions.
- #021
Once the cabal had decided which gameplay elements Half-Life needed, smaller mini-cabals were formed from the departments most affected to put them in place; membership of the main cabal rotated, because the workload burned people out.
- #022
Marc Laidlaw saw his role on Half-Life as adding "old storytelling tricks" to the team's ambitious designs; he felt he was borrowing from old standards while the team was doing something truly new.
- #023
Instead of handing down story ideas as the inspired author, Marc Laidlaw improvised with the Half-Life team and took inspiration from their experiments; the opening train ride came to him after an engineer wrote train code for a different idea.
- #024
Valve first planned traditional cutscenes for Half-Life, but switched to an unbroken first-person view because it was running out of time.
- #025
With most of the major changes to Half-Life done, the team added ways to measure what players were doing and used the statistics to fine-tune the levels further.
- #026
Birdwell says the cabal approach was key to Half-Life's success despite its early struggles, and Valve used it from the very start on Team Fortress 2.
Behind the Scenes (2)
- #027
The game is full of artillery bombardments, and the 'whistling' before each explosion is the sound of a German Flak 88.
- #028
The cabal took an active part in Half-Life's playtesting, watching players without interfering and noting any confusion or unsolvable puzzles as problems to fix in the next round.

The book in Freeman's locker, "The 37th Mandala", is by Marc Laidlaw, who wrote Half-Life.
- #030
The names on the bathroom lockers at the start of the game, and on the footlockers in the Half-Life: Opposing Force (1999) training level, belong to people who worked on both games.
- #031
"Security 7G" is written on several security doors, a reference to Homer Simpson of The Simpsons (1989), the safety inspector for Sector 7-G of the Springfield Nuclear Power Plant.
- #032
Before the flooded room in the office complex chapter, a sign gives directions to Dr. Newell, the surname of the game's creator, Gabe Newell.
- #033
Level designer Dave Riller slipped his surname into the game at least twice: once on a locker near the beginning, and again as a well-known Easter egg hidden under a HECU outpost in the Materials Transport, on map "c2a2c", where it can only be seen from one particular angle.
- #034
The game's files contain a longer version of the G-Man's line for players who refuse to join him. He starts with the familiar "Well, it looks like we wont be working together. No regrets Mr. Freeman," but then mentions "a few survivors of your personal holocaust" who would "like to meet the man responsible for the total annihilation of their race".
