Doom 2D is a fan-made DOS-based freeware side-scrolling video game based upon Doom, somewhat like Doom 2D - Knee deep in the dead, only older. Doom 2D is essentially the original Doom translated into a two-dimensional arcade or console-like shooter, comparable to the original Duke Nukem. The player resumes their role as Doomguy, who must do battle with various hell-spawn. Originally appearing entirely in Russian, eventually a partially-translated English version appeared and both are still available for free on the Internet.
