Blendo Games has publicly released the source code of its latest game, Skin Deep, encouraging other developers to build more stealth games in its footsteps—or at least to take a look at the sick game engine it built. I, for one, am shocked by a specific thing about it: It runs on a core of idTech4, which you may recognize as the engine behind Doom 3.
"The original idTech4 was made in 2004, so we had to implement a lot of things that were now expected in a modern 2025 game. It was a lot of work!," said Blendo on its blog. "Gameplay in Skin Deep is quite different from Doom 3, so the gameplay code likewise has a large amount of additions and changes."
