David Szymanski is the creator of the game Dusk, which was released in 2018 and is inspired by classic first-person shooters like Doom and Quake. He initially developed short horror games before achieving success with Dusk. Szymanski has also created a submarine horror game called Iron Lung, which gained recognition after being adapted into a film by YouTuber Markiplier. He categorizes the history of first-person shooters into distinct eras, labeling the '90s as the silver age and the late '90s to mid-2000s as the golden age. He enjoys survival crafting games like The Forest and Subnautica but has not finished them. The oldest game installed on his PC is Doom, which he considers nearly the best FPS ever made. His most-played game on Steam is Counter-Strike 2, with 324 hours, and he has spent 186 hours on Elden Ring. Szymanski would never uninstall Infra, which he describes as his comfort game. He uses GIMP as an essential non-gaming software tool and has a relatively tidy desktop with nine icons.
