Multiplayer: enables multiplayer functions.Gameplay: changes the way the game is played.Configuration: access to settings or files.The parameter descriptions in the list below are preceded by practical identifiers which give a general idea of what the general effect of each parameter is. Other games with Doom-based engines, such as Heretic, Hexen, and Strife, also use the same parameters with only slight differences, mostly because of required customizations or because they are based on earlier versions of the Doom engine that did not include all the parameters available in the latest versions of the Doom games.

Doom95, for example, accepts the usual parameters but adds a launcher to be used by default for all purposes, and various source ports add a console that can handle most options and variables, or support drag-and-drop capabilities that take care of some of the start-up options. Since ports often rely less on the command line and more on a graphical user interface they may have alternate ways of entering commands and parameters. Ports of the Doom engine usually retain most if not all the available parameters, and sometimes add some of their own, or customize some of the original ones. Earlier versions of the engine, particularly up to 1.2, tend to require the -devparm parameter (that enables 'developers mode') to use many of the parameters, but later versions do not require it. While most parameters are available to all the released versions of the Doom games, some became obsolete with newer versions, and some were added as features were enabled or changed. Note that if you warp internally using the idclev cheat code, any parameters that required warping will be disabled. Unless stated otherwise, parameters work for all versions of both Doom and Doom II, with some exceptions that are detailed accordingly in their descriptions. The extra program will also warp the player to the first level of the game if no other warping parameter is used.

In deathmatch and cooperative modes an extra program called a device driver by the Doom documentation handles some of the multiplayer specifics and passes any parameters to the main executable. Many parameters that affect in-game behavior require warping through -wart, -warp, -episode, -skill, -playdemo, -record, or -loadgame, or else they are overridden when the user starts a game through the menu. Any number of parameters may be typed in, limited only by the maximum length of text allowed by the interface (for example, a 127 character total in some DOS versions).

The command line may be the MS-DOS command line, or any compatible interface, such as a batch file, the command line or target entry in a shortcut's properties dialog box, the Windows Run command, or the command line in DOSBox. The parameters are typed after the executable's name in the command line and are followed by variables or text strings, if applicable. In respect to the Doom engine a parameter (or command line parameter and command line argument) is a start-up indication by the user that the engine should change its default behavior.
