We recommend that you torrent the client due to its large size (5.3 GB compressed, 12.5 GB uncompressed). It prevents interruptions due to server maintenance, avoids corruption due to browser problems, and puts less stress on our servers. We recommend qBittorrent to torrent the client. Just install it with the default settings and use either the .torrent file or magnet link above to download and seed the client.

  1. Is 0.6.1 stable yet, I heard on the comments that there were still some glitches?

    • ALOT better that 0.6. You should use it but if you don’t like the little glitches stay with 0.5.1. ๐Ÿ™‚

      • Yeah, there are glitches because it comes straight from the new github source by jon and knight.

        • Hey, TimTech Can you make a updated guide on how to get the game to work? Thanks!

        • I’m new at downloading things like this so would it be ok if you made a video how to download 6.1. like every part of it. i have it but the loading takes forever, i don’t know if its broke or not since the scenes on the right switch. Though thankk you fro your hard work on this i had some great times on LU, even got a textbook guide on it.

        • Are then ur old chatacters back ? I would love to get back my lv 32 Paradox Space Rober Tier 3 ;-(

          • No, all of the old characters and accounts are gone. The good thing about this is that you don’t need to have had a subscription or even played at all before in order to use this software.

      • how to use the easy world changer?? for 0.5.1

        • Run (double-click on) the .jar file, and browse to the installation of your LUNIServer 0.5.1. From there, just follow the instructions and you should be fine. (If not, I can help you).

  2. I want to make a new character but I need passwords to be able to delete them.
    I am using 5.1.

  3. Is it safe to download these? I don’t wont to be hacked!

  4. the nexus file has nothing in it when I download it

    • How big is the file that you downloaded? Check it with Right-Click > Properties. You might have got an impartial download. You should try a different browser to see if there is a difference.

  5. Help when i open Nexus2 i cant start the installer i get an Error

    • U have to Extract all Files from Nexus 2 and the 0.5.1 Server ! Than start the Luni Server from the Extracted and that Legounivers from the Extracted Nexus 2

  6. When I install the Nexus file it will only go 1.3gb / 5.3gb Then it will stop – I’ve tried changing browsers to no avail.

  7. Why can’t I join 0.5.1? Everytime I say register, then type in Rexdive and enter it. It starts saying LUNI not responding. Windows cannot respond to LUNI and it shuts down. Please help, I want to play Lego Universe again, its been so long!

  8. Hey I am not a computer specialist but I glib globbing loved this game. I didnt know what the adventure is coming to an end picture on the launcher meant so when I tried to log on and it gave the message about it being shut down I sobbed for like 30 minutes. Will there be a public server available soon.

  9. When will the game be finished?
    And when will you add quests, being able to edit character with weapons and clothes and will you make a public server. I hope so i want to play the game fully completed.
    I know you are working hard but im just curious. But i hope it will be finished soon.

    Just tell me some details pls.

  10. Waschbรคr May 30, 2015 @ 9:40 AM

    Everytime i login the game crashs ๐Ÿ™

  11. Everytime i start the 0.6 Luniserver i get this error: “Terminated Unable to connect to database! PRESS ENTER TO QUIT” pls help me ๐Ÿ™

  12. The Luni 0.6.1 server crashes when i login in the game ๐Ÿ™

  13. I’m on Windows 8.1 and I’m running the 0.5.1 server , when I open the legouniverse.exe i t runs the loading screen for about 3 seconds then crashes

  14. I need Visual studio 2013 also now? (in 2015) If yes. Please give me a link. Thanks! ๐Ÿ˜‰

  15. When I switch worlds using the separate world changing application, it tends to spawn me “outside the map”. Sometimes I can get back to the world using the jetpack item, but other times, such as in nexus tower, I’m stuck somewhere that seems to either be far below or on top of the game map. Anyone know a fix to make characters spawn correctly?

  16. Big Swole Martin June 2, 2015 @ 6:36 AM

    I am really looking forward to this! When will it be fully complete?

  17. hi, whenever i open 5.1 and try to register a new account (when lu was out, i never had a chance to play it ๐Ÿ™ ), and i type in a username, it crashes it. what should i do? (at the moment of this post, i am downloading nexus2)

  18. What can i do with the nexus2 client?

  19. Is their a tutorial with words? i find it hard to figure out what to do when they are silent

  20. If i create a character i can’t play with them. I can’t click on play button. Pls help me! Thanks! ๐Ÿ˜€

  21. Thanks for making this available, Tim. I’ve been meaning to make an account for a while now, and I’ve finally gone and done it!
    I’m still having some trouble booting up a server, but I expect a little more trial and error will get me there.

  22. Every time I try to download the file I get really bad download speed. This only happens when I download from the browser but for other clients such as Steam I get 4 MB download speed! Please help!

    • We don’t have unlimited bandwidth ๐Ÿ˜‰ currently someone is uploading a large copy of LEGO Universe Rebuild so speeds might not be the fastest. And anywhere above 1 MB/s is a good speed for this site.

  23. Is this Project still alive? Maybe i could host the new global server and maybe i would help if i can and when you say me what could i do!

  24. so i really dont understand what im suppose to do also nexus takes 4ever to download so i can never download it if someone could skype me and explain it better that would be great ๐Ÿ˜€ thnx

  25. View my coomment on faq plz timtech

  26. TheExterminator June 9, 2015 @ 2:09 PM

    How much space does the nexus2 client take up when extracting it?

    • Around 13 GB.
      I know this is really big, but you just must download it once and you can play LU, the best game ever with it. ๐Ÿ™‚

  27. when i tried to use jon’s easy world changer (release), i get this message from java virtual machine launcher- could not find the main class de.cuzitsjonny.ewc.Main. program will exit. any help would be apriciated! @Timtech

  28. Finally! It’s like a dream come true ๐Ÿ™‚

    • Yes! Cool, that you also think like us.
      Maybe you are willing to help?
      You can make videos, tell it your friends, help other people with their problems or (if you can code) develop the LUNI Server further.

      • Yeah i can code. It comes easy to me but im still a student so yeah… ill see if i can do anything. Videos of course im working on a youtube channel atm so i can start doing that, Finally I’ve been telling my friends.

  29. When will factions quests and maelstrom be enabled??

  30. I was wondering if it was normal when I’m running the 0.5.1 server, I can’t seem to be able to press shift to interact with anything. Just wondering if that feature has not been implemented yet.
    Also I’m trying to run the LUNI Server 0.6.1 and it keeps saying that I’m missing libmysql.dll ? Is there something that I have to copy to make it work? Thanks!
    Awesome work by the way.

  31. Ok so after I’ve downloaded the Nexus client my computer won’t let me open it. It says windows can’t open the folder because it is invalid. This might be a stupid question because I’m kind of new to this but any suggestions on what I can do?

  32. Hi I am having trouble opening the nexus client in order to play Lego universe. When I try to open it it says Windows cannot open the folder because it is invalid. Any suggestions on how I could get it to work?

  33. monkey tanfield June 25, 2015 @ 12:36 PM

    hey it’s me again i have not been here a while, is the launcher what i think it is open it and it load’s the game instantly?

  34. You need programmers, eh? Well, I can’t promise much, to be honest. I’m fairly busy so may not be able to spend a lot of time on it, and I also don’t really know what you need. I know Lua script, but beside that my knowledge is limited to the easy and useless stuff, like hmtl and css.

    • Jon’s repo –

      It’s got some “getting started” stuff. Hopefully you can continue from there ๐Ÿ™‚

      P.S. The HTML and CSS rendering this comment are not useless (although it might be easy)

    • Also, I have a question: Do I need LEGO Universe installed? Like, the original one? Do I still need my old account?

      • Well, you’ll need to install LEGO Universe. Unless you downloaded the full client, you’ll need to download it from this site. The same goes for the server. Old accounts were removed so they won’t work here.

        • If that’s the case, what do we use to log in? I want to make sure I know the full info before downloading

          • Servers 0.5.1 and below accept any username and password. For 0.6 and above, you’ll need to use the register command in the server console to register a new user account into the SQL database.

  35. o meu lego ele fala que nao foi encontrado nenhum servidor

  36. I tried 0.6.1 and when I play it stays at 0%, was Venture Explorer not put in yet or is this a glitch or did I just install wrong? I followed the instructions from a video.

  37. Hi! Why when I try 0.5.1 I have lag? Works, but in lag. Someone can help me? Please ๐Ÿ™

    • It sounds like your computer is laggy. Right click on Computer, click Properties, and list the basic system details you see to me so I can check if it’s your hardware limits that is causing the lag.

  38. when will the next client version be available and how can i help develop LUNI? I love this game! Well, loved… ๐Ÿ™

  39. Happy July 4th!

  40. Tim i recommend fully finishing the first area so when you make a new character you arent stuck at a loading scream that literary never ends. I wish you good luck and wish i could help, but sadly im just a very good gamer no coder. keep the good work up!

    • I’m with you, good gamer; not so good coder. Plus I think this game is C++ coded. I barely have any experience with java. Just if\then statements and a basic calculator. ๐Ÿ˜

  41. how is 7.0 coming?

  42. Hello there! I’d just like to know if new characters are able to get in-game right after character creation (0.6 has an empty database). With 0.6, I get stuck at the loading screen, so I’d guess character creation is not fully implemented yet?

    • 0.6 has a world loading bug; 0.6.1 source should let you access worlds (but not with your newly created char, although that char will save in the database).

  43. when trying to run .6.1 compiled server, i get the message
    Terminated unable to connect to database!

  44. how i want play with people

  45. How can i get the 32bit version for win xp SP3?
    when i try to open server appear this “luniserver.exe is not a win32 valid application”

  46. both

    • I guess your operating system (Windows XP) is to blame since these programs run on your Windows 7 machine. Try compatibility settings for the programs (right-click > Properties > Compatibility) and see if there is something that you can change that will make it work, although I doubt it because compatibility usually makes older programs run on newer systems, not the other way around.

  47. the 6.1 server talling me that im missing libmysql.dll how do i fix
    and one more qreshon eney eta on the next update and whut have you guys been working on

  48. I posted the link of the page and that LU is back under 126 Videos of Lego Univers on YouTube.
