back to article Doom at 25: The FPS that wowed players, gummed up servers, and enraged admins

On December 10, 1993, after a marathon 30-hour coding session, the developers at id Software uploaded the first finished copy of Doom for download, the game that was to redefine first-person shooter (FPS) genre. Hours later IT admins wanted id's guts for garters. Doom wasn't the first FPS game, but it was the iPhone of the …

    Wolfenstein 3D, Doom, and Quake. Oh happy times. Where I worked at the time, blocked playing it during business hours with immediate termination if you were caught (two were and set the example for the rest of us). But after hours, half the engineering department stayed at their desks (including management) for several hours. After playing that, I started learning programming and changed careers to IT.

    I think ID did change a lot of things with the first getting non-techies into IT. There were a lot of "engines" out there in that time and many of probably got our start working with the engines and coding.

    Have a pint, ID... for the stuff legends are made of.

      It's amazing to think there are only 12 months between Wolfenstein and Doom. I wish we could still see leaps like that.

      1. WallMeerkat Bronze badge

        The 90s were full of huge leaps like that. If you took a PC from 1991 and a PC from 1998 it was incredible the difference.

        Whereas if you took a PC from 2011 and from 2018 there really isn't that much of a difference.

        Even in the console world we started the 90s transitioning from 8 to 16 bit, then via the 32/64 bit Playstation-Saturn-N64 era, by the end of the decade we had Dreamcasts and getting ready for Playstation 2 - many of the games of which still hold up today.

        Mobile phones too, 1990 these were rare, brick like, and still had a whiff of finance yuppie about them, by the end of the 90s they fitted in your pocket, everyone had a mobile (thanks in part to PAYG) and they were getting internet connectivity (remember WAP?)

        All credit to iD games...

        But hardware advances were a key driver of the improvements between the two games.

        W3d would (grudgingly) run on a 286 with just 640k of ram; Doom's official minimum spec was a 486 with 4mb of ram, though it would judder along on a 386 if you were desperate.

        Moore's law was very much the game developer's frenemy back then - it gave you more memory and CPU cycles to play with, but if you misjudged your release window, then your game would be either unusably sluggish or woefully primitive as compared to the competition.

        Hell, people still occasionally ask if $thing will run Crysis ;)

          Yes but it had to be a 386DX - wouldn't run on an SX. I know...I had to swap my motherboard and/or CPU.

          It's so long ago I can't really remember if it was just one or both or if they came as a unit back then.

          Didn't the original crash WAN links due to each round fired from the minigun being a while IPX packet? (None of that fangled TCP/IP back then, no siree).

          My mate and I used to have two desktop PC's (and 15" CRT's) on the dinning room table and connected by serial cables...or that might have been a bit later with Duke Nukem 3D.

          Fabulous fun though.

            Yes! I worked for a large broadcaster back then that nearly lost it's network because of Doom. Not only affected Netware IPX/SPX, it affected the Cabletron spanning tree if I recall correctly.

            Doom was later assigned its own port # 666

            Re: 386DX

            Not true. I ran it on an AST brand 386SX/25 with 4 MB of RAM. Yes, I had to shrink the game play window down about half way, but it was still playable (definitely not 30 fps, but playable). I do remember having to reboot with a clean AUTOEXEC.BAT and CONFIG.SYS to free up enough memory to play, though.

              Re: 386DX

              Original Doom was fully playable on a Dan 486DX with 4MB of RAM and a Spea V7 video card, I can report. As was original shareware Quake.

              That PC was a snip at only £1700, and that's 1993 money.

            So many of us experiencing identical flashbacks, especially the Dragon 32 to Amstrad 464 (and then 6128).

            Serial cables at the dining table were a thing at mine for while but soon I scored for some old cheapernet cards and hooked up a small token ring. I may be wrong but I only recall up to four players on head to head and can't recall internet play, but that might have been the limitations of my setup back then.

            I do recall LAN parties involving mates bringing base stations, CRT monitors, Soundblaster speakers / headphones, keyboards and mice for a whole weekend. Used to flip between Doom, Quake, Duke 3D, Heretic and Rise of The Triads.

            Ah the chicken spell in Heretic. Halcyon days.....

            I am certain Doom didn't need a math co-processor- a 386sx was slow, but would work. I played it that way. Quake, on the other hand, required an fpu, as we'd call it today.

            1. Pirate Dave

              Re: All credit to iD games...

              Yes, Doom didn't need a math-co, but Quake did. I know because at the time Quake came out, I was using a NexGen NX586, which (for reasons that elude me) didn't have a math chip in it. So I missed the early Quake bus until I saved up enough for a real Pentium. I had to while away my time playing Doom Eternal, Final Doom, etc...

              Re: All credit to iD games...

              The 386SX was a 386 with a 24- rather than 32-bit external address bus; After the SX was introduced they rebranded the original as DX just for differentiation. None of 'em had an on-board co-pro, pretty sure. DX denoting an on-board co-pro was strictly 486 nomenclature.

              Ho hum.

        "It's amazing to think there are only 12 months between Wolfenstein and Doom. I wish we could still see leaps like that."

        That is amazing. Some similarities to the home computer boom of the early 80s perhaps. Huge differences between products launched a year apart. I was lucky enough to have a Dragon 32 and an Amstrad cpc464. Admittedly, the latter was slightly more expensive and launched 20 months after the Dragon, but the difference was enourmous. Double the RAM, almost 5 x the MHz, much improved BASIC, larger keyboard, bundled tape recorder, monitor...

        For that matter, look at the Sinclair ZX81 vs the Spectrum. An even starger contrast, only 13 months apart.

      When Doom launched in 93, I was a Unix systems administrator. We had no Doom plague on the Unix estate for obvious reasons. What we did have was pre-web Internet, enabling us to grab doom via FTP, copy the zip file and take it home on a floppy (or 3). University of Washington kindly had it in their FTP archive IIRC, one of the biggest on the Internet. What was it? or something.

      Okay we might have had the Mozilla browser by that time. Memory fades.

        Really? I worked for Sun at the time, and someone decided that Doom would be a cool demo for the new SPARCstations. A loaner system (SS5 IIRC) was arranged and Solaris port of Doom appeared (I don't know if money was exchanged, probably so). It was available free to customers.

          Doom on UNIX

          Yep my memory as well starting uni in early 1990s. Doom was available for a ton of UNIX systems by a few years after release. Kind of remember seeing it on IRIX as well and people were amazed by the frame rate but not the people who programmed it usually in the computer lab. Remember them yawning at the graphics (didn't use hardware accel I think) but playing none the same.

          "Really? I worked for Sun at the time, and someone decided that Doom would be a cool demo for the new SPARCstations."

          Excellent, and not surprising that somebody at Sun would do this, being an innovative place by nature. However, Unix Doom must have come some time after Doom was launched on the PC, which is the era I was talking about. By the time I left in '95, Doom had not made it to our Sun network, but the software engineers had written themselves a version of network Battlezone, seemingly.

            I still have the binaries (but sadly no SPARC system with a graphics card). The earliest ones date from the Christmas holidays 1994/5, late Dec to early Jan, but I guess I'd have had them before they were widespread outside the company.

      We had 2 devs sacked for playing it. We used to play it on the graveyard shift with the security staff using the training room where the PCs where all set up. On nights we did play the network backups would take about 20% longer to complete, our daytime counterparts in Ops could never work out why! Ha ha!

      Ah, happy memories. I remember spending a weekend in early 1994 networking a minor civil service department. How did we test the network? By installing Doom on certain Windows-enabled computers and playing an all-night death match ...

    "Hordes" of monsters, please

    I didn't really think of the monsters as little treasure chests you got to loot.

    The only way I got through the game was after learning about the GodMode cheat. To this day, it's one of the few games I've actually completed in its entirety. (Damn open world games and their never-ending side quests for feathers or whatever!)

      It was easy to recognize the God Mode alumni during death matches, especially hen we switched to Quake.

    It was great fun

    I was doing an HNC in Mechatronics at the time and I think every computer in the college had Doom 1 on it. I can see the sysadmins' problems even if the students didn't.

    It was great fun and the best thing about it was that it was a relatively small and simple game. Even on 486s, which is what the college was equipped with, it was quick to load. 5 - 10 minutes to kill ? You could have Doom up and running and be blasting baddies within about 30 seconds. I came back to it about 15 years later, v3 I think. Came on a DVD, about a 2GB install and took five minutes before you could shoot anything, and that was on a reasonable to good computer. It had lost the spontaneity and had become the preserve of serious gamers

      @Phil Endecott; 3D Monster Maze was impressive on a machine that was never intended to do that sort of thing (especially consider that it came out the same year as the ZX81 itself). I have to point out though, that while it had the "first person" bit, it wasn't a "shooter". (#) Now that I think of it, I'd love to see a version that let you shoot back at Rex ;-)

      @GruntyMcPugh; Yes, I agree that "Phantom Slayer" looks better- but to be fair, the Dragon 32 (and its near-twin the TRS-80)- were somewhat more graphically advanced machines than the ZX81.

      (#) Making it more what would be described nowadays as a "survival horror".

    Yes, there are newer, better-looking FPSes around, but Doom occupies a space in my life that it shares with only a handful of other games from the general era: I still play them regularly to this day. The others? SimCity 2000, Civilization CTP, Redneck Rampage, Master of Orion - both 1 and 2 because they are very different games.

    I still fire up DOSBox every so often and have a play of both Doom and Wolf 3D, and these days the new titles in those series are about the only games I buy.

    Lots of nice touches in the games, such as the big shit eating grin from BJ in Wolf 3D when he found the gatling gun. The horror aspect of Doom with the dark areas was ground breaking too.

    Doom and Wolf 3D are a bit like the first Black Sabbath albums, they laid the platform for what was to come even if they seem a bit primitive in parts now. I feel justified with the heavy metal comparison given the Doom soundtrack was strongly influenced by metal, some of the level music is inspired by Metallica, Slayer and Pantera.

        Thank you sir, loved "A Vulgar Display of Power".

        The metal influence is still there in the franchise, if anyone has played Wolfenstein: The Old Blood they will know the end title song is a cover of La Complainte du Partisan performed by Mick Gordon with Tex Perkins on vocals and it is spectacularly good.
