DOOM – Aday

The game was created by id Software, founded by a group of highly influential developers:
John Carmack (technical genius of the graphics engine)
John Romero (game design and creativity)
Tom Hall (initial ideas for story and style)
Before Doom, you had already had success with Wolfenstein 3D, which was one of the first first-person games, but quite limited technically.

John Romero was key to the level design. He created highly complex, fast-paced maps full of secrets, designed to encourage constant exploration and movement. He also championed the idea of a more intense and aggressive gameplay experience.
