Doom (1993 video game)
Doom (typeset as DOOM in official documents and stylized as DooM in other media) is a 1993 first-person shooter (FPS) video game by id Software. It is considered one of the most significant and influential titles in video game history, for having helped to pioneer the now-ubiquitous first-person shooter. The original game was divided into three nine-level episodes and was distributed via shareware and mail order. The Ultimate Doom, an updated release of the original game featuring a fourth episode, was released in 1995 and sold at retail.

In all of its platforms except the Nintendo Switch, "Doom" includes a built-in level creation tool called "SnapMap" which allows players to create and edit maps with their own structure and game logic. With SnapMap, players can create maps for different modes, ranging from single-player levels to co-operative or competitive multiplayer maps. When players are building a level, the game will shift to a top-down view. Players can place rooms and hallways to form a level and connect them together. If they are not connected together, the color of the construction pieces changes to notify the player. Players can also use the X-ray camera which temporarily removes all the walls to allow players to view the objects inside. Players can also place enemies into their maps, with the exception of the campaign's bosses. Their artificial intelligence and stats, and the player's own movement speed can also be modified. Players can also add additional particle effects, lighting effects, and other gameplay items, such as health packs and ammo pick-ups. Only in-game assets can be used, and players cannot create or import their own models into the game. Levels can be tested before they are published online.
