Doom references in other games
The popularity of Doom has resulted in a large number of homages in other games.
- Angry Video Game Nerd Adventures, the first officially sanctioned game featuring the Angry Video Game Nerd character, contains a level called "Thy Farts Consumed" in which the Nerd descends into Hell to face giant "cacademons" and flaming skulls. A video of the level is available here.
- Its sequel, Angry Video Game Nerd II: ASSimliation, features the cacademons in many of its levels.
- In the adventure game The Bizarre Adventures of Woodruff and the Schnibble (known in Europe as Woodruff and the Schnibble of Azimuth) there is a scene in which Woodruff plays a Doom-like virtual reality game and shoots down a monster looking like a demon with a shotgun.
- In Damage Incorporated, the video-game-loving marine codenamed Vidiot will occasionally quip "Woah, this is better than Doom!" during missions.
- Duke Nukem 3D contains a slaughtered marine who looks like the Doomguy, which causes Duke to remark, "Hmmmm, that's one doomed space marine".
- Dungeons of Dredmor is full of references to other games, Doom included. The third level of the dungeon uses the "Moon Base Dredmor Alpha" theme, reminiscent of the UAC base on Phobos. One of the Steam achievements for the game is "Realms of the Id", which is obtained by equipping the green armor and the "rusty helm" (from Quake, which is also referenced with the "interdimensional axe").
- In the MS-DOS versions of Earthworm Jim and Earthworm Jim 2 (collectively titled The Whole Can O' Worms), typing in the Doom cheat codes iddqd or idkfa displays a humorous picture.
- In Jazz Jackrabbit 2, in the episode-selection screen, the player is allowed to try the shareware demo of the game. The episode screen is a parody of the Doom II box-art and even the text "Shareware Demo" is written using the Doom font. This is ironic since the game was released by Epic Games, the creator of Unreal and the biggest competitor of id Software's Quake franchise.
- The randomized title screen phrases in Minecraft drawn over its logo include several related to Doom. These include "idspispopd!", "MAP11 has two names!" and "Phobos anomaly".
- The PC game Muppets Inside features a Doom parody starring the Swedish Chef taking on giant killer vegetables with various kitchenware.
- In Chapter 38 of the crossover video game Project X Zone titled "The Lord of Puppets," when facing off against Street Fighter IV's villain Seth for the third and final time, Juri will say she'll drag Seth down to hell, and Xiaomu says to say hello to the cyberdemons when he gets there.
- Quake Champions features the Doom Slayer as depicted in Doom (2016) as a playable combatant with a special attack based on the berserk power-up and a passive ability to double jump courtesy of his Delta V jump-boots. Previous incarnations of the Doomguy (classic look and Doom 3 look) are also available as cosmetic options. 
- Quake II was host to an easter egg in which the Doom logo appeared in a room full of John Carmack-related paraphernalia. Most of the weapons available in the game are also updated versions of the weaponry in Doom, including an upgrade of the BFG named 'BFG 10K'.
- Quake III Arena features the Doomguy as a playable character; he is referred to simply as "Doom". The same model, with a different skin, is used for the character "Phobos". A female character wearing a strikingly similar helmet, known as "Crash", is referred to as Doom's former mentor.
- The Quake III and Quake Live level Dueling Keeps includes art that is strikingly similar to the Doom II final boss.
- Radix: Beyond the Void, a 1995 hybrid of first-person shooter mechanics and Descent-like gameplay by Neutral Storm Entertainment, contains a recreation of a portion of E1M1: Hangar as a tribute to Doom's influence on its creators.
- Rage contains an easter egg room with Doom textures in the Gearhead Vault part of Subway Town. The entrance is a locked door behind a Mixom crate; the door can be opened by activating computer keyboards that make the Doom powerup sound until a demon growl is heard. Entering the room teleports to a partial recreation of E1M1. Similar easter-eggs also exist for Wolfenstein 3D and Quake. Other Doom Easter eggs include, among others, the "Pinkies" snack (a parody of Twinkies), the Doom II title screen adorning Siri's hookah, the concept art for the Doom 3 version of the spiderdemon as a graffiti, a Wellspring NPC reading the Doom comic, and the character watching a Doom demo on the targeting screen of the rocket launcher when idle.
- In Soldier of Fortune II: Double Helix the Doom title screen is shown on the personal computer of an enemy sailor on board the Seaward Star (mission 4).
- In Sin, in the Biomech security compound (level 10), one of the security terminals conceals an easter egg. If the player accesses the command prompt, they can use DOS commands to navigate and launch gloom.exe. Unfortunately, after going through the Doom-like loading sequence, Gloom: Heck on Earth will fail to start due to a mouse not being present.
- In Konami's Super Famicom game Ganbare Goemon 4, one part requires the player to avoid gunshots from a pistol in the foreground. The pistol sprite is clearly based on Doom's.
- In Spyro 3: Year of the Dragon, in the Fireworks Factory level, a first-person shooter sequence must be undertaken using the laser-blaster-wielding monkey known as Agent 9. The game gives the names of the two Dragon eggs to be recovered in this area as "You're doomed!" and "You're still doomed!".
- In Tomb Raider III's Nevada Desert level, there are a bunch of workers in blue suits. All of them have the easily recognizeable image of a lost soul displayed on their backs.
- The PC release of Tony Hawk's Pro Skater 3 features the Doomguy as a secret skater. He is unlocked on the cheat screen by typing idkfa.
- In the Simpsons game Virtual Springfield there is a minigame called "Apoom" with a parody of Doom in which Apu fights off squishee-throwing bullies in his shop with a broom, shotgun and a weapon similar the BFG, causing them to explode in a bloody mess.
- In the Atari Jaguar port of Wolfenstein 3D, the Pistol, Chaingun and Rocket Launcher sprites are taken from Doom.
- In Wolfenstein: The Old Blood, a cacodemon chew toy can be found on a doggy bed.
- World 4 of Mushroom Kingdom Fusion is themed around Castlevania, Ghosts 'n Goblins and Doom. The demo version includes World 4-2, "Tower of Babel" , which incorporates graphics and music from Doom. The World 4 map is that of Doom Episode 3's intermission map. Tower of Babel incorporates imps and cacodemons, as well as a cyberdemon boss. Mario may pick up and fire Doom's rocket launcher in the boss battle.
- In Super Columbine Massacre RPG!, one can collect the Doom box at the beginning of the game. Later in the game, the player will face several Doom enemies, including imps and demons. The cyberdemon appears as the second to last boss. Upon defeating him, the player is rewarded with a BFG.
- Cyberdemons are found in the Roguelike game ZAngband and many derivative games, such as Gumband, Hengband and ToME. There they have similar characteristics to cyberdemons in the Doom series, although they have been given a tremendously strong close-combat attack (four strokes for 150 damage each) in addition to their traditional rockets. Also, the unique monster "Oremorj the Cyberdemon Lord" can be found in ZAngband and Hengband (Oremorj is Jromero, i.e. John Romero, read backwards).
