The Resonator is an artificially engineered enemy that I designed for Affray Studio's debut game, Pandemic. Based on SCP 5000, the game is a hardcore cooperative first-person tactical horror shooter releasing on PC, MacOS, and Linux.
I designed the creature to follow the visual direction of Ivo Francisco (bathroomtile)'s Infector, keeping the pale skin, dead eyes and spidery growths consistent, but with a slightly more refined anatomy. The reason for this was simple; the more dangerous and beast-like a Psi-Z is engineered, logically the more control and functional ability the creature in question would have over its body, making each iteration a higher in-game threat. I also added many different features, such as the Demagorgon styled mouth, extremely vascular muscles and spinal extensions to incite more fear in the player upon discovery.
In low lighting, I imagine something like this growling and panting would be utterly terrifying...
