To prevent the obliteration of life as we know it, you'll have to battle your way past deadly hazards and devious creatures, or end up as space toast.

    Wasn't there 7 Commander Keen games?

    • +5

      I remember Episode 6: Aliens ate my babysitter

    • +8

      "Keen Dreams" and "Aliens Ate my Babysitter" are missing. Yes there are 7 games.

      • +17

        How dare they call this "complete".

        • "Keen Dreams" and "Commander Keen VI: Aliens Ate My Babysitter!" (6 and 7) were not ID/Apogee.

          This is for the complete ID Soft / Apogee collection.

      • +6

        yep I played keen dreams on dos and still remember the vegetables

      • +1

        I remember something a bit weird about those… weren't they put out by a different publisher or something?
        Pretty sure they weren't part of the official numbered titles.

        • +1

          Different Publisher and the rights have turned hands numerous times. Pretty much abandonware at this point.

        • +1

          @SLY JD: Yup, these are the ones publihed by 3D Realms

  • +1

    This would be great as a mobile game.

    • +2

      They're on the Google Play store.

    • +8

      There's a recent episode of LGR where he hooked up a floppy drive and IBM Model M keyboard to an Android phone via USB OTG and played Keen and Jill of the Jungle.

      • +9

        yeah, and it confirmed to me why you wouldn't want to play these games on a mobile device.

    • +8

      For the authentic Keen mobile experience, it is best played directly off a 3.5" floppy drive and IBM Model M keyboard plugged into a mobile phone.

    • +1


      Add the datafiles from the steam version and enjoy :)

  • +1

    Where is number 6, "the alien ate my babysitter"?

    • -4

      Probably banned by the progressives, politically incorrect?

      • I seem to sort of recall that it might not have been by the same makers or something. But I might be wrong, it's a quarter century ago after all.

  • +2

    (in)complete Commander Keen series.

    God this brings back some memories.

    • -1

      Wrong. It is complete, as authored and released by ID / Apogee.

      "Keen Dreams" and "Commander Keen VI: Aliens Ate My Babysitter!" (6 and 7) were made by a different company.

      • It might be all the ID / Apogee Keen games, but it is not the complete Commander Keen series of games, exactly as i stated.

  • +7

    Nostalgia hit!

    From memory, episode 4 was what made this series iconic. One of the better PC platformers from the era. It's what came from the developer, id software, before Wolfenstein and Doom and Quake.

    • +10

      I remember the process on a friend's DOS computer:

      <insert disk>



  • +1

    Good price, but it's not the entire series. Episode 3.5 (Keen Dreams) and episode 6 are missing. Strange that they have most but not all of them.

  • +1

    Love it!

    • +1

      I agree!

  • +9

    These are one of the first games that I remember playing.
    We had a PC running an Intel 8086 XT processor 4.77Mhz with 640Kb of memory and MS DOS 3.2.

    • This just might be one of the first I remember playing too.

      How do you know your first comp. specs as a kid?

      • +3

        my first comp specs was a:
        486 33 mhz with 4 megs of RAM
        MS-DOS 5.0 and Windows 3.1

        later i upgraded to a:
        486 DX2 66 mhz and 8 megs of RAM
        added a Sound Blaster Pro and a 2x CDROM DRIVE!
        MS-DOS 6
        Windows 95

        so many fun times had

          @Diji1: Idunnoareyoutire? Trymoresleep?

        • DX?!? What the hell were you using that fancy math coprocessor for?

      • -2

        386DX2/66… doesn't everyone remember their first computer? ;)

        • +2

          the 386 processors never came as DX2.
          the fastest 386 released was clocked at 16 Mhz

        • +2


          the fastest 386 released was clocked at 16 Mhz

          Intel: 33 Mhz

          AMD: 40 Mhz

        • +1

          @DiSTURBED-oNE: Quite right! You know your stuff… Got my 2nd computer confused with my 1st.

          1st - 386DX 40 (AMD)
          2nd - 486DX2 66 (Intel)

        • My first Laptop was a 286SX-25 - 40mb hard drive from memory - 3.5" floppy.

          Weighed more than a small car

          Cost nearly $2.5k back then…

          I was rich (?!) from selling shareware back in those days - Commander Keen made me a small fortune…

          EDIT: actually my first computer was a VIC20, then a Commodore64, the Amiga500 - Then I hit the hard stuff… IBM Compatible PC - 286

          I bought one of the first CD-Rom drives in AU - Slot cartridge type - Those were the days…

        • @glenr:

          I can remember making a conscious choice to go for a 486DX40 AMD as the Intel version was a comparably slow 486DX33, you know like a whole 7Mhz slower.

        • @kamoi: I stand corrected.

      • +4

        286! Which hosted one of the greatest games ever developed; Their Finest Hour - The Battle of Britain by Lucasfilm. Alley Cat wasn't bad either.

        • The Battle of Britain the first computer game I ever played. So much Nostalgia.
          Do you remember F-15 Strike Eagle II ?

        • +1


          Yesssss! I got it for Christmas in (I assume) 1989 or 1990, as an 8 year old WW2/aircraft enthusiast I sunk hundreds of hours into it. Memoriesssssss.

        • +2


          Never played Strike Eagle. I did play F-117A Stealth Fighter but nothing compares to BoB.

          Check this out.


        • +2

          @mr fox: F-117A was my fav for a few years.

        • I had the Alley Cat theme song as my phone's ring tone, but it's since been relegated to an alarm tone.

      • +5

        I was fascinated in that PC. I learnt everything about it.
        I loved the thick manuals it came with… I remember reading them cover to cover. Suffice to say I now work in IT.

    • We bought a Pentium 166 machine with 16mb ram, 1.9gb Quantum Bigfood drive, 96x cd-rom for $2000. Unknowingly it was a fake Pentium 166! It performed pretty badly, but once we upgraded it to a Pentium 233 with MMX it rivaled the Pentium 2 performance. Dropped a 3dfx Monster Voodoo in there and I could play Unreal at 640x480! What a crisp resolution!

  • +10

    Lol.. is it safe to say all commenters here are pre 1990?
    I remember pulling all nighters playing this on my 386 with 1mb of ram and 80mb HDD

    • +10

      1mb of RAM? You probably lived on the rich part of town

      • +6

        640K ought to be enough for anybody

      • He comes from the city of HIMEM

    • +2

      Don't think there were too many pre-schoolers playing Commander Keen!
      Pre-1985 more like it

      • I used to play it in the late 90's - our computer wasn't good enough to play doom, or even wolfenstein.

      • +3

        I was born in 1988, and smashed this game as a kid, but it was more around the 93-95 mark when I got it.

      • They did release it on Game Boy Color

      • lol wasn't even born….

  • +2

    This, Clyde's adventure, and Duke Nukem were go to.

    • +4

      Also Prince of Persia, Civ I, Tetris & DOTT…. the memories.

      • +1

        Just bought Crystal Caves too.

  • Never actually played a full version Keen before. Tons of shareware though. Can't remember the limitation - maybe just the first few levels?

  • +1

    I'm KEEN to play this again

  • +10

    Fun trivia: B.J. Blazkowicz (Wolfenstein hero) is Commander Keen's grandfather and Keen is Doomguy's father

  • +4

    Massive 25MB download guys, hope you all have the NBN.

    • +10

      Can someone download it and I'll bring over 18 floppy disks?

      • +5

        I'll zip it so we can squeeze it on to 15 disks.
        See you in 5 hours after it finishes compressing and writing!

        • +1

          WinRar bro!

        • Cut the notch out & use the other side of the disk man

    • Of course we all have it! Malcolm personally sent me a letter JUST before the 2016 election PROMISING we would have it at the end of 2016! And you know Cayman Mal, he cannot tell a lie !

      (of course we still dont have it)

      • +1

        Malcom's job is too enrich Telstra. I know that's not what his title says but if you watch what he does you see what he's about.

  • I already have this! Haha

    Awesome games from my childhood

  • Still have these boxed and sealed. They were awesome growing up.

  • Keen

  • +8


    Now have to find a copy of Jazz Jackrabbit!

  • +2

    Good memories playing the Commander Keen games hadn't thought of them for ages, cheers OP. Other games from that era that I played were Captain Comic, Alley Cats, Ancient Art of War at Sea, Battle of Britain, Leisure Suit Larry I, SimCity and Sim Ant.

    • Don't forget Jill of the Jungle!

    • +1

      Raptor & Dig Dug

    This is neat.

      • I don't think anyone is getting my Keen reference. :(

        • I hope you put "Fluent in Standard Galactic Alphabet" on your resume.

        • +2

          @XyzzE: I was. I could read all the signs, I could write notes to my friends… It was great. It's obscure enough now to write encrypted messages to friends again.

  • There was also Keen 6 'Aliens ate my baby sister', and Keen's dreams (like version 3.5).

  • this game was the bomb as a kid lol

  • This game was legendary

  • If you still have the original floppy disc, you can play on your phone using the tutorial below featuring Commander Keen ($1.66 saving).


  • Aren't these free on abandonware sites? Why would I pay for them? How is this a deal?

    • If they are still being sold, how are they abandonware?

    • That's what I was thinking. But Steam, install them anywhere, cloud save, probably trading cards and achievements.

      • No Steam cards or achievements.

        Steam loads Dosbox (PC Emulator).

  • I remember that red (profanity) robot gave me nightmares as a kid. Still kept playing though.

    • The Dopefish of Keen 5. Just not as cute.

  • Oh gosh, thanks for posting this, such good memories of sneaking off to play it at school!

  • I seem to recall spending days playing Commander Keen, yet I just finished episode 1 in about 20 minutes. Was I that bad at games as a kid?!?

  • great memories!

  • awesome memories :)

  • +2

    I remember playing this when it first came out. Was able to download the first shareware episode for free from BBS services back in the days of dial up internet. The remaining paid episodes weren't supposed to be shared but they always ended up on BBS services and easy to find.
