"DOOM-where the sanest place is behind a trigger."
There's plenty of other cool stuff that can be added to this page!
This is the press release announcing the game and the capabilities of its engine:
Id Software 1515 N. Town East Blvd. #138-297, Mesquite, TX 75150 FOR IMMEDIATE RELEASE Contact: Jay Wilbur FAX: 1-214-686-9288 Email: email@example.com (NeXTMail O.K.) Anonymous FTP: ftp.uwp.edu (/pub/msdos/games/id) CIS: 72600,1333 Id Software to Unleash DOOM on the PC Revolutionary Programming and Advanced Design Make For Great Gameplay DALLAS, Texas, January 1, 1993-Heralding another technical revolution in PC programming, Id Software's DOOM promises to push back the boundaries of what was thought possible on a 386sx or better computer. The company plans to release DOOM for the PC in the third quarter of 1993, with versions planned for Windows, Windows NT, and a version for the NeXTall to be released later. In DOOM, you play one of four off-duty soldiers suddenly thrown into the middle of an interdimensional war! Stationed at a scientific research facility, your days are filled with tedium and paperwork. Today is a bit different. Wave after wave of demonic creatures are spreading through the base, killing or possessing everyone in sight. As you stand knee-deep in the dead, your duty seems clear-you must eradicate the enemy and find out where they're coming from. When you find out the truth, your sense of reality may be shattered! The first episode of DOOM will be shareware. When you register, you'll receive the next two episodes, which feature a journey into another dimension, filled to its hellish horizon with fire and flesh. Wage war against the infernal onslaught with machine guns, missile launchers, and mysterious supernatural weapons. Decide the fate of two universes as you battle to survive! Succeed and you will be humanity's heroes; fail and you will spell its doom. The game takes up to four players through a futuristic world, where they may cooperate or compete to beat the invading creatures. It boasts a much more active environment than Id's previous effort, Wolfenstein 3-D, while retaining the pulse-pounding action and excitement. DOOM features a fantastic fully texture-mapped environment, a host of technical tour de forces to surprise the eyes, multiple player option, and smooth gameplay on any 386 or better. John Carmack, Id's Technical Director, is very excited about DOOM: Wolfenstein is primitive compared to DOOM. We're doing DOOM the right way this time. I've had some very good insights and optimizations that will make the DOOM engine perform at a great frame rate. The game runs fine on a 386sx, and on a 486/33, we're talking 35 frames per second, fully texture-mapped at normal detail, for a large area of the screen. That's the fastest texture-mapping around-period. Texture mapping, for those not following the game magazines, is a technique that allows the program to place fully-drawn art on the walls of a 3-D maze. Combined with other techniques, texture mapping looked realistic enough in Wolfenstein 3-D that people wrote Id complaining of motion sickness. In DOOM, the environment is going to look even more realistic. Please make the necessary preparations. A Convenient DOOM Blurb DOOM (Requires 386sx, VGA, 2 Meg) Id Software's DOOM is real-time, three-dimensional, 256-color, fully texture-mapped, multi-player battle from the safe shores of our universe into the horrifying depths of the netherworld! Choose one of four characters and you're off to war with hideous hellish hulks bent on chaos and death! See your friends bite it! Cause your friends to bite it! Bite it yourself! And if you won't bite it, there are plenty of demonic denizens to bite it for you! DOOM-where the sanest place is behind a trigger. An Overview of DOOM Features: Texture-Mapped Environment DOOM offers the most realistic environment to date on the PC. Texture-mapping, the process of rendering fully-drawn art and scanned textures on the walls, floors, and ceilings of an environment, makes the world much more real, thus bringing the player more into the game experience. Others have attempted this, but DOOM's texture mapping is fast, accurate, and seamless. Texture-mapping the floors and ceilings is a big improvement over Wolfenstein. With their new advanced graphic development techniques, allowing game art to be generated five times faster, Id brings new meaning to "state-of-the-art". Non-Orthogonal Walls Wolfenstein's walls were always at ninety degrees to each other, and were always eight feet thick. DOOM's walls can be at any angle, and be of any thickness. Walls can have see-through areas, change shape, and animate. This allows more natural construction of levels. If you can draw it on paper, you can see it in the game. Light Diminishing/Light Sourcing Another touch adding realism is light diminishing. With distance, your surroundings become enshrouded in darkness. This makes areas seem huge and intensifies the experience. Light sourcing allows lamps and lights to illuminate hallways, explosions to light up areas, and strobe lights to briefly reveal things near them. These two features will make the game frighteningly real. Variable Height Floors and Ceilings Floors and ceilings can be of any height, allowing for stairs, poles, altars, plus low hallways and high caves-allowing a great variety for rooms and halls. Environment Animation and Morphing Walls can move and transform in DOOM, which provides an active-and sometimes actively hostile-environment. Rooms can close in on you, ceilings can plunge down to crush you, and so on. Nothing is for certain in DOOM. To this Id has added the ability to have animated messages on the walls, information terminals, access stations, and more. The environment can act on you, and you can act on the environment. If you shoot the walls, they get damaged, and stay damaged. Not only does this add realism, but provides a crude method for marking your path, like violent bread crumbs. Palette Translation Each creature and wall has its own palette which is translated to the game's palette. By changing palette colors, one can have monsters of many colors, players with different weapons, animating lights, infrared sensors that show monsters or hidden exits, and many other effects, like indicating monster damage. Multiple Players Up to four players can play over a local network, or two players can play by modem or serial link. You can see the other player in the environment, and in certain situations you can switch to their view. This feature, added to the 3-D realism, makes DOOM a very powerful cooperative game and its release a landmark event in the software industry. This is the first game to really exploit the power of LANs and modems to their full potential. In 1993, we fully expect to be the number one cause of decreased productivity in businesses around the world. Smooth, Seamless Gameplay The environment in DOOM is frightening, but the player can be at ease when playing. Much effort has been spent on the development end to provide the smoothest control on the user end. And the frame rate (the rate at which the screen is updated) is high, so you move smoothly from room to room, turning and acting as you wish, unhampered by the slow jerky motion of most 3-D games. On a 386sx, the game runs well, and on a 486/33, the normal mode frame rate is faster than movies or television. This allows for the most important and enjoyable aspect of gameplay-immersion. An Open Game When our last hit, WOLFENSTEIN 3D was released the public responded with an almost immediate deluge of home-brewed utilities; map editors, sound editors, trainers, etc. All without any help on file formats or game layout from Id Software. DOOM will be release as an OPEN GAME. We will provide file formats and technical notes for anyone who wants them. People will be able to easily write and share anything from their own map editors to communications and network drivers. DOOM will be available in the third quarter of 1993.
A few things that didn't make the cut or changed:
- Four defined characters were dropped in favor of each player being a nameless marine.
- The RAM requirement by the time of release was bumped up from 2MB to 4MB.
- Walls cannot change shape or move in the final engine.
- Messages are never displayed on walls, there are no access terminals or anything of the sort, and walls can't be visibly damaged.
- Palette translation is never used to indicate different player weapons, hidden areas, or monster damage.
The Doom Bible
The Doom Bible was written by Tom Hall for the development of Doom, but it would soon be decided by the rest of id Software that The Doom Bible was to be mostly ignored. The only thing from The Doom Bible that survived was the name Knee-Deep in the Dead, which would be used as the name for the first episode of Doom in its retail release.
Dubbed "The Blob", this monster concept would spawn off any wall, animate, and spawn a Lost Soul. Its spritesheet was retrieved from a backup image of one of id's NeXT development servers by an anonymous source. The spawning Lost Soul graphic would later be reused as the inside of the Pain Elemental's mouth in Doom II.
Early and Unused Maps
These map images were provided by the same source as The Blob spritesheet. They were taken with Doom Builder.
A small unused map apparently consisting of staircases with a monster closet at each landing, leading to two larger rooms. There's a Cyberdemon in the last room.
This is E1M1 from the 0.5 alpha, but with added sections and things. Curiously, the additions are very similar to the ones made to the final E3M1 in E3M9: Warrens.
An early version of E1M8: Phobos Anomaly which is closer to E1M12 in the 0.5 alpha than the final version of the map. Since the alpha, a number of things have been added, some detail sectors and sound blocking lines, and the large room with the Barons of Hell has been brightened.
An interesting take on E2M2: Containment Area. Its texturing is closer to the final map than E1M2 in the 0.5 alpha, but its geometry is still rough compared to E3M2 in the pre-beta. Even stranger, some of the geometry is closer to the final map than the pre-beta, such as the door to the room with the chainsaw being around the corner from the start point.
An early version of E3M2: Slough of Despair. The level layout is mostly the same, only missing the "booger" at the top of the middle finger and a few dividing walls, but a number of detail sectors are missing from it.
21st Birthday Art Release
Erred on the side of caution with stuff that was actually used in the alphas. Should go over those assets at some point and see if the ones Romero released are earlier/newer.
On December 10, 2014 (Doom's 21st birthday), John Romero released a large number of in-development and unused art assets for both Doom games on Twitter.
Graphics in Development
Captures of the player sprites, with one frame near final. Based on the filename, this is actually the Zombieman, though, and the first frame is actually present in the 0.4 alpha.
The (Pinky) Demon's legs were actually drawn over a capture of a toy dinosaur!
Grayscale captures of the Baron of Hell, with some early work isolating the different rotations for its head.
A capture of a skull, which would be the basis for the Lost Soul.
Captures of different Cyberdemon poses, the first in grayscale and color.
Test captures of the Spider Mastermind — these are larger than the ones used for the final sprites.
A toy beretta, painted black, which would be used for the pistol. It includes some angled captures not used by the final animations.
A capture of a toy, which would become the chaingun.
A sketch of the episode 1 intermission map background.
Sketches that would become the episode 2 and 3 end graphics.
Demon face sketches in the process of being cleaned up, to be used as wall and floor textures. The last sketch would also become the final boss in Doom II.
Circuit board photos that would be used as the basis for some of the TEKWALL textures.
An early title screen, apparently pasted over an id Software logo.
A more finalized copy of the logo used on the screen above.
A possible backdrop for the title.
This is the original font drawn for Doom.
An earlier style for the BFG9000.
In the final game, a number of monsters' right-facing frames are just mirrored copies of the left-facing frames, likely to save space on the disk or in memory. The right-facing frames for the player and enemy marines were drawn, however. Here are the player sprites...
...the Zombieman, with WIP copies of the edits made to the marine in the scratch space on the right of the first frame...
...and the Shotgun Guy.
An unused player decapitation death animation.
At one point in development, the Spider Mastermind was going to have a magic attack that likely would've held the player in place, leaving them vulnerable to the demon's normal chaingun attack. This is a frame for it.
Various projectile and impact sprites, some of which were unused but still present in early releases of the game. The notable thing here is the impact in cell 26, 17, which looks to be a larger blood spat and has never been seen before.
Frames for two different styles of bush, with two burned variants of each. These may have been intended for Doom II, given its setting on Earth.
Marble wall carving textures featured in the final game, but with alternate eye styles/colors for one of the demons included.
An updated copy of SKY1 from the pre-beta, recolored, with a lot more detail added to it.
(Terribad) Sign and monitor patches to go on walls. Some of these were used in the alphas, but most weren't.
Early wall and door patches, and an id logo.
The source image for the big door and lift patches. Unlike the final doors, this one was intended to have a transparent bottom, and looks like it might've been designed to open both up and down. Doors with transparency aren't really (intentionally) possible in the Doom engine, so they ended up giving the final doors a flat bottom instead.
Some pipe patches intended to be used on wall textures.
A wall labeled "Don't use", so they didn't.
Window midtextures, some unused.
