Idle Doom mod turns Doom 2 into an idle game

The thrills of gibbing demons and sitting still watching numbers go up combine in Idle Doom, a mod turning id Software’s seminal face-paced FPS into an idle game where you watch a machine kill monsters so you can upgrade to a bigger monster-killing machine. It is exactly what it sounds like: a Doom idle game. It’s just the ticket for people who want to feel like they still strafe rough and frag hard but, really, they’re quite tired so it would be grand if they could put their feet up with a cuppa and let someone else handle things for a bit and oh please turn the light off on your way out, ta.

It’s simple. Demons are teleported from Hell into an courtyard, where gun turrets automatically fire at them. Their deaths get you money, which you can spend on upgrading to stronger and faster weapons. You can also upgrade the enemy types and spawn rate, because killing more and stronger enemies naturally gives you more money. We’re simply standing in a control room overlooking the courtyard, controlling the deathmachine by bopping buttons and watching everyone die.

Actually, Idle Doom does something few commercial idle games do: gives a clear sense of where to focus upgrades. If enemies are dying as quickly as they’re spawning, you’re doing all right. If this gets out of whack as you upgrade weapons and enemy types, it’s easy to figure out how to correct it.

If this sounds ludicrous to you, if you suspect it’s some sort of ‘joke’ for comical effect, some tomfoolery and monkeyshines you cannot stand, don’t worry: Idle Doom’s readme file tells a serious story.

Doomguy was relaxing after a busy day. He was playing some games on Firefox 829. Suddenly, he had an idea. He phoned his friend at UAC, John Science.

John: Hello, Doomguy! How are you?
Doomguy: Unf! Urgh grunt!
John: An idea to effortlessly destroy all of Hell? We run a teleporter to Hell, pull them in one by one and a we fire half a dozen BFGs at what comes through? Sounds good! Can’t see that going wrong!
Doomguy: Ungh oomph!
John: I’ll talk to my boss tomorrow, see if he thinks we can do it. Pass by the lab when you got the time.

The next day…

Doomguy: Yeaargh!
John: Hey there, bud! I talked to my boss and I got some bad news. UAC cut our funding on Hell-related matters. Screaming something about “more rendering servers to the megatexture gods!,” whatever that means.
Doomguy: Urgh…
John: Don’t worry, it wasn’t a flat out no. We got a pistol and a small teleporter.
Doomguy: Go f*** yourself!
John: Easy buddy, no need to get brutal. We show them that the idea works by killing demons and he gets us funding to upgrade the system. We’ll build your dream killing machine. Let me show you the prototype…

And yes, it does have an actual ending.

Released back in May, Idle Doom is made by ‘Albertoni’ with ‘Negrostrike’.

Albertoni notes in the readme, “If it doesn’t make someone ask ‘why?’, it’s not a map worth making.” I approve of this design philosophy.

You can download Idle Doom from /idgames mirrors, as listed on Doomworld. You’ll need Doom II and I recommend GZDoom for an updated engine (always remember to turn OpenGL texture filtering off). Once everything’s download and installed, you’ll be able to simply drag the Idle Doom file onto the GZDoom executable to launch it.

Happy fragging! You’ve earned a quiet cuppa today.

    Two posts about idle games in the same day seem to me to be a signal. Let it be known that Cookie Clicker was updated last week.

    I fell off the wagon. Hard.

    (that being said, I’d love to see RPS interview Orteil.)

    • jellydonut says:

      Cookie Clicker is still alive? I don’t know if I would call that an idle game, at least not the last time I checked..

      Meanwhile I’m playing swarmsim which is quite idle for my needs.

      • GeoX says:

        It’s the very definition of an idle game. What else would you possibly call it?

    This is an idle game that i am okay with reading about.

    When do we get a Doom 2016 version? That’s the real question here.

  4. Blackcompany says:

    Is that…Jacksonville, FL in the Background?

    • sithmaster says:

      The city so nice they named it Jacksonville.

      • Blackcompany says:

        Beats Cow’s Ford, which was the previous moniker, believe it or not…

          Early migrants to the US really didn’t have much imagination when it came to place names did they?
          It’s either a basic description of the place (Cow Ford), the name of a person with -town added to the end (Jacksonville), or they’d just re-use the name of somewhere back in Europe (Birmingham, New York etc.)

          • poliovaccine says:

            I mean that’s definitely true, but for all the many repeats, as you start getting out west you start getting some more creative names. Truth or Consequences, New Mexico is a favorite of mine, or also in New Mexico, Radium Springs, which sounds like a town straight out of Fallout – not least for the name, but also cus the town has a lower crime rate as a direct result of the naturally-occurring Lithium in the water, haha.

            Things definitely get weird if you push west and away from population centers haha. Something about desert seems to bring out the deep weirdness of man!

          • Addie says:

            That would be exactly how most place names in the UK came about too, except they were called that in anglo-saxon / celtic / old norman / norse / etc, and it’s not so obvious to us anymore since the language has changed over time.

            Edit – thinking about it, there’s plenty of US placenames (Nevada, Colorado, Florida) which seem unique, since they’re Spanish really.

    Aren’t the developers of this game aware of the law that idle games must run in a browser? Apart from the developers being criminals, this looks good.

  6. Chaz says:

    Urm, what’s an idle game? Two posts about idle games in one day and I have no idea what you are refering too.

  7. jcvandan says:

    “Idle Games”. This is a frickin’ ridiculous concept XD. How is this a game?!
