This Half-Life designer is sharing early prototypes on TikTok

You can find all sorts of weird stuff on TikTok these days—including, as it happens, an extremely early prototype of the original Half-Life courtesy of level designer Brett Johnson.

Spotted by The Tax Goblin on Twitter earlier today, Johnson has recently shared a few peeks at Valve's debut shooter early in development. As noted, this appears to be long before Half-Life really found its visual identity, with concrete corridors more reminiscent of Quake than the final game's more grounded facilities.

Joining Valve shortly after its founding in 1996, Johnson's TikTok feed goes over his work on the genre-defining FPS, occasionally showing brief clips of cut content and answering questions about the game's design (including a two-parter on Half-Life's notorious Xen chapters).

Today's post is the deepest dive into unreleased content he's given yet. In the comments, he notes that this clip is from a period where he was still "searching for a style", using the very first photo-referenced textures. The segment was supposedly intended to represent an industrial block hidden just behind the labs, and sports a much more abstract architectural style more typical of Id's shooters.

Johnson does note that more of this level was discarded than ultimately used in the final game. But even if it these halls never made it into Black Mesa proper, it's a fascinating reminder that Half-Life didn't spontaneously appear out of thin air. These things had to be figured out, and I'm excited to see if Johnson posts more of these prototypes in future.
