"Those are all Quake 2 textures with a bit of messing about to fit the theme - since doing this I've figured out how Quake 2 RTX materials work and modded it to load higher resolution models in maps so could improve on this a lot. There are a few free photorealistic texture packs out there that include stuff like that but would need some adjustment (roughness/specular, normal and metal/chrome maps) to make them materials in Quake 2 RTX." -Rroff

"The release of Doom II in 1994 was one of the most unnoticed letdowns of the gaming world. The sprinkling of a few new enemies and one new weapon were enough to give Doom junkies their fix, but the game was a mere baby step forward in every way. Now, Quake 2 appears to have finally broken id's sophomore jinx, with so many improvements over the original that, for once, the two games look markedly different."
"How do you top the awesome 3D action of QUAKE? All the gaming heavyyweights — including LucasArts, 3D Realms, id Software, and Raven — are working on that very question with the next generation of first-person shooters, which promises to take the genre even further. This month, we grab our rocket launchers and hunt down the most promising QUAKE killers of 1997."
"Few words stir a gamer's heart like 'Quake' does. Having conquered the world with Doom, id Software have been busy lads of late, alternating between taking phone calls from their Ferrari mechanics and knocking up another masterpiece. Great expectations have been placed on id, but whatever form Quake takes, it will surely disappoint some, just as it will unconditionally please most of the rest of us. A visit to the action games newsgroup on the internet shortly after ANY new 3D game is released shows heated debate. All new games are compared to Quake, despite the fact that until recently nobody outside id actually knew anything about it."
