RimWorld first public pre-alpha released

Posted by Tynan Sylvester (Creator)

All right! It's out!

Backers whose payments succeeded in the first day should be getting emails with links to download the first public pre-alpha, build 250.

There is one bug you should know about - sometimes the game starts and the screen is black. To work around this, just move the window a bit.

If your payment was not successful the first time around, you have two options.

  • Give up on Kickstarter and just go to and get the game there. You'll get instant access.
  • Fix your payment with Kickstarter. I'll send you the link not long after November 14, when Kickstarter gives me the final report.

If you want to read the changelog, find it here.

Discussions, suggestions, and bug reports are always welcome at the Ludeon forums. I'm also on Twitter.

Don't get trampled by the muffalo!

      Oh I only have the $20 dollar tier anyway.... why did I be stingy :(

    2. Niclas von Ahsen on

      I also haven't gotten the link even though my email says it was successful on the 1st of November. However according to may bank statement the payment only went through yesterday. Just noticed this and it might be the reason why a lot of people think their payment occurred on the 1st but they still haven't gotten their key.

    3. Tobias Svärdh on

      I have the same problem as many others, hanv't got the link. The payment was successful 1st of November and there is nothing in my spamfolder...

      Look in your deleted folder. May be in there Just found mine there. Looks like some one didn't want me playing!

    6. Bill Briggs on

      How do I get the link? I may a payment but no email was sent. I have my bank statement saying I paid on the 4th of Nov. What does the email subject or title say that I'm looking for?

    8. Dillyo09 on

      Me and my friend love playing this, to bad it doesn't have multiplayer.

    9. Bill Briggs on

      Yeah, my payment went through and I haven't seen an email either. It wasn't caught by my spam filter.

      Got the game yesterday and have had the chanse to put a few hours into it (no sleep for me).
      I love it and are totally hooked and can't wait to see how it evolves.
      Will we get updates on this version or is it all comming in the alpha release?
      Time to start a new round and see what terrible fait that awaits the poor souls.

      When it says those who paid successfully on day 1, does that mean day one of the funding period? I got an email today saying payment was successful I don't know if that was the first day in question though. Any ideas?

      disregard that, It was stuck in my spamfilter

    14. Anthony Bonome on

      Nevermind, I made a mistake. I will be getting the Alpha, not Pre-Alpha.

      my payment was successful on day one, no email

    17. Anthony Bonome on

      I successfully paid, yet do not have the link.

    18. Alexander Eriksson on

      and again, play for 2-3 hours and then had two raids in a row and got horribly murdered. (first one had 6 people, SIX PEOPLE
      second one had FIVE)
      I was sitting on FOUR. four people and 5 turrets, and we still got horribly murdered by the second wave.

    19. Mandi Mae Killip on

      My payment was successful on the first day but an email has not been sent. I assume they're going out in batches :) $30 tier btw.

    20. Jonathan Cook on

      Ugh! Can't wait! All you early access guys are lucky.

      @ Theo Benvenuti
      Nope. 20$ tiers will only get RimWorld in January 2014. On the other hand, this version will be more feature complete and polished.

      Theo Benvenuti on

      Hi, am I supposed to get the email if I only payed 20$?
      Guess not since I didn't received it. :/

    23. James Bray on

      Oh don't worry, I don't get the pre-alpha anyway! Ignore!

    24. James Bray on

      Hi there, my payment went out okay on the 1st, but I have not received an e-mail with a download link. Any ideas?

      ignore that just found the email... the sending address caught me out lol

      colin stapleton on

      how do i check if my payment went through ok? is it just a case of checking my bank account or does kickstarter show it?

    27. Stevepunk on

      Scratch that, I missed the email ^^"

    28. Stevepunk on

      My $30 payment was successful on the first day but I have not received a download link.
      I have build 232 already so will play that in the meantime, but it would be nice to have 250 and future updates.

      I'm enjoying the game so far :)

    29. Nick SSP on

      I just spent the last 6-7 hours playing non-stop nearly. Kassandra classic was good till you just get successful, then she spills the raids on you when you haven't had a chance to recoup. Phoebe is nice to get the feel down though. No matter what though the game is awesome and seeing as this is alpha I have a lot to look forward too!

    30. Alexander Eriksson on

      Kassandra classic is too hard for newbies, and phoebe is no fun...
      Kassandra just threw 4 raids pretty much in a row at me

    31. Anaanamus on

      For a pre alpha this works really, really well. Granted it just makes me feel like I'm playing Dwarf Fortress mostly at the moment, but I consider that a compliment and not a complaint.

    32. Akira Currier on

      Ty, just wanted to thank you for the game. Pretty hard to believe it is pre-alpha. Just so you know, Rimworld caused me to be late for work today ;)

      Looking forward to seeing what the final product looks like.

    33. Justin P. King on

      Im super excited to play this, but i haven't received my code yet. probably someone intercepted the email and stole it. Be right back my network assassins are requesting my presence. I'm sure ill have this fix in just a few moments.

    34. Rex705 on

      Sweet I can't wait to play it I have it downloaded and ready to go. :)

      Good stuff on getting the codes out so early. Really looking forward to playing this sucker!
      Cheers, from the distant land of Gatineau

      I literally just started up the game, haven't even left the main menu yet, but I figure I might as well mention this now since I have the same issue with a LOT of games - at some point, could you add an option to adjust the font size in the game? I realize that's more difficult than it sounds because it messes with interface layout but it would be really nice to have in there eventually. I have my PC hooked up to my TV so it makes the very small text on 1080p difficult to read from where I sit (since I'm a lot farther back than I would be with a monitor).

    37. Troy Lonergan on

      Fantastic stuff, totally unexpected. Thanks Tynan :D

    38. LexC on

      Too awesome for words :) Let's do some testing

    39. Tynan Sylvester Creator on

      Alexandre - Thank you! I was really, really not looking forward to trying to trace this bug.

      Just downloaded and played through. This game is surprisingly playable and polished already. I honestly suspect this game is going to become one of my all-time favorites.

    41. Wild Factor on

      About the Bug: I had the same bug with a full screen post process.
      The dirty fix I've got is in a monobehaviour :

      void Start ()
      if ( !Screen.fullScreen )
      Screen.SetResolution(Screen.width, Screen.height, Screen.fullScreen);

    42. Allions on

      Thanks mate! I got it... 3 days... Fantastic!

    43. Ocelot113 on

      Amazing job on getting the list so quickly! Can't wait to play!

      Thank you Tynan!

      I just found my email with the was in my spam folder...

      If you don't see the email, it may be in your spam - the address that is it coming from is:

      Make sure to white list this one.

      Now I suddenly remember why I love Steam so much - Limited downloads on SendOwl (And similar download sites - Prison Architect uses a similar one)

      Hope nobody manages to screw up their download three times in a row, hah.

      Damn! can't wait to see how this game will shape up in the coming months, you seem to have something really great happening here!

    48. Aaron Stoner on

      Now I kind of wish I pledge more money for the game.. XD

      Oh well.

    49. Tynan Sylvester Creator on

      @Anthony - Yes, this is for Influencer backers and up. Colonist backers will get the game in January, at the more polished first public alpha stage.
