Half-Life locked the camera behind your eyes for its entire runtime, with no cutscenes and a protagonist who never speaks. This episode traces how former Microsoft employees Gabe Newell and Mike Harrington founded Valve in 1996, licensed the Quake engine and rewrote roughly 75 percent of it into GoldSrc, drew on Stephen King’s The Mist and the manga Akira, and then hit a wall in late 1997 when playtesters found the game a disjointed mess.

The hosts explain the Cabal, six people from different departments locked in a room for months building one Die Hard meets Evil Dead prototype and three rules of fun, and how novelist Marc Laidlaw turned an improvised tram ride into environmental storytelling for Gordon Freeman’s resonance cascade. They cover the flanking Marine AI, the tentacle boss as a stealth puzzle, the widely criticized Xen platforming, Monica Harrington’s hardball with publisher Sierra, over 50 Game of the Year awards and 9 million copies, Worldcraft shipping on the disc and spawning Counter-Strike, German censorship replacing Marines with robots until 2017, and the 25th anniversary update in 2023.
