Call Of Duty Modern Warfare 2 LAN

Updated on June 18, 2013

MW2 LAN


As we all know by now Infinity Ward decided against dedicated servers, meaning players could not create their own private place for playing with clan/friends or host private dedicated servers. The matchmaking runs on a peer to peer hosting system (Yes this means lag/high ping/Disconnects). The news was not greeted kindly by the PC Gaming Community and was a devastating blow to the pirate community.

I feel Infinity Ward are right to make their game as less pirate friendly as possible but not at the expense of the paying customer who pay their wages, Always support software/games developers

This page is to explain in easy steps how to play Co-op Special Ops (two player scenario missions) privately over LAN (Local Area Network) or with a friend over the internet.

Things you will need:

  1. Call of Duty Modern Warfare 2.
  2. Co-op Files : http://www.multiupload.com/AU3V04HF7M (all files needed in one package including the Teknogods Loader).
  3. Tunngle, found here: http://www.tunngle.net/index.php?l=en

What To Do Next:

  1. Download and install Tunngle. It will ask to reboot your PC after installation so reboot your PC.
  2. Start Tunngle, and create an account.
  3. Click on browser on the bottom left of the program to choose the type of game you want to play. Choose ‘Shooter’, and then choose MW2 from the list.
  4. Open your Call Of Duty Modern Warfare 2 directory.
  5. Unrar the coop.rar file downloaded from the link above, open the folder named "coop" and copy and paste the contents into your Call Of Duty Modern Warfare folder clicking "replace" when asked.
  6. Start TCSB.exe and hit refresh. You will now be able to see the servers hosted by other players in the Tunngle MW2 channel, simply hit "join" to join a host. If you are alone or if you want to play with your friend, host a server and tell your friend to join that. (You must be in the tunngle MW2 lobby for TCSB to find hosts).
  7. If you joined a host: after the game has loaded, On the main screen before you choose any game mode hit F12 to join the current hosts game.
  8. If you host a game: simply set up the game in two player special ops mode and wait for someone to join your game.


NEW GUIDE BELOW


Testing?

Yes I tested this method a lot. I have had many game sessions that lasted hours with no lag and no problems.

The only thing that let me down from time to time was Tunngle, don't get me wrong It's a good program, However it is still in beta testing and the server can go down sometimes for short periods of time.

Possible Dedicated Server Mod In The Future?

Yes I'm 100% sure there will be private dedicated servers in the near future. There are many people working on making one currently, The PC Gaming Community is screaming out for one.

I will make another tutorial on how to use these dedicated servers when the information is available, so check back often.

So What Are You Waiting For?

Get fragging! and I'l see you in the Tunngle lobby!

Happy Gaming

ps. If any links expire comment and I'l upload/create new ones.

      TwoDee 7 years ago from UK

      No that is not possible... yet! The Teknogods loader 1.1 will run the game in a steamless environment, and its apparently going to be released sometime over the xmas holidays. It also supports PRIVATE DEDICATED SERVERS! finally we can all say screw you Infinity Ward.

      Yes. It is currently in development check it out here : http://teknogods.com/ The guy who runs the site did a radio interview and he says "we are trying to release it for xmas"(you can find a link to it on their forums)

      these guys are professional software reverse engineers, so it will be done, just a matter of time.

      Hope this info helps :)

      SUPERSEAL 6 years ago

      Woo hoo i got the Lan version, only problem is that for example you need 8 players to play Search and destroy.

      anybody know of a script to change this.

      This game in lan was awsome, south africa data lines suck big time, so playing on lan was a great experience.

      I did all of the instructions in order to play MW2 2player ops and after all of the file replacements my iw4sp.exe doesn't run. Nothing happens... Any idea what might be the problem here? I'm using tunngle, I have extracted the co-op folder and the game just dies.

      TwoDee 6 years ago from UK

      Hmmm. This info is almost a year old. I'm not sure if this still works because of a years worth of updates and it uses steam. You could always play real multiplayer by checking out my other hubs. I will look into the problem and let you know if there is an update you can try.

    • profile image

      SadPlayer 6 years ago

      Weird, because my friend did exactly as I did and his game runs. He can run the 2player special ops and even host. My game however, doesn't want to start the single player. (multiplayer works fine, just the sp doesn't even run)

      If you use a router, you need to forward port 11155 for tunngle.

      If you don't have a router, or you opened port 11155 already then I don't know, but if your friends works, chances are something went wrong on your pc.

      For this guide Yes. However in theory it is possible to use this without tunngle if you have 2 pc's in the same building connected to each other, but I am unable to test it because I only have one gaming PC.

      and I just wander :

      if I have a private network (ex: a LAN behind my IP-sharing switch)

      could I just play with my LAN PC without connect to Internet (Tunngle) ?

      THANK YOU SO MUCH!

      p.s. I am from Taiwan :-)

    • TwoDee profile image

      TwoDee 6 years ago from UK

      in theory yes it could work, but I have not tested it.

      No there is no virus, it must be a false positive try scanning it with virustotal, I did not make those files they are just repackaged from the teknogods forum because it requires registration to download from there.

      張旭 6 years ago

      thank you so much!

      I could link to my LAN PCs with Internet,

      one of my LAN PCs as a server

      one as a Client

      but when I press F12,

      it wants me to login "Steam" :-\

      when I went to the Two players mode of Special Ops,

      it always remind me "Must have Two Players to start this mission" :-(

      I just could not see the picture that you showed in this blog.

      with steam or without steam, both the same.

      Me 6 years ago

      First of all thanks for your efforts. OK, I am about to embark on this, but I have couple of questions:

      1) Do you need TWO Steam accounts in order to play on LAN (I am planning to install it on my secondary PC as well)

      2)Would you kindly provide the link for how to setup a LAN for PC?

      Thanks!

    • profile image

      Me 6 years ago

      3) Can you play ANY Maps with this method? I mean can one PC act as a SERVER and the other on as CLIENT (typical id software DOOM style LAN play that is), or is it just for a CO-OP?

      I am trying to play on 2 gaming PCS in the same room, behind the same router. Can I play LAN?

      Thanks!

      TwoDee 6 years ago from UK

      Ok... Yes you need a dummy steam account.

      This guide uses tunngle and the internet to make a virtual LAN, this method is only tested using tunngle as a LAN client, but you could hook up 2 PC's with ethernet cable and try that.

      This method is for Co-Op special ops objectives.

      If you play around with it im sure you could get it working

      To play CoOp, do you need two copies of MW2 or just the one?

      I have a hack so CoOp being online isn't going to happen.

      Is /this/ a way to get around it? (for either a hack or one copy)

      I've been thinking about (finally) purchasing MW2 but if it's $180 just to play CoOp, uuuurgh, I won't bother.

      Thanks!

      This guide is for previous versions that need steam to be running in the background. most torrent clients on the net today do not need steam. Check the teknogods forum for updates and info. Or check my other hubs and find the guide to play normal multiplayer using alteriwnet

      MW2 Lan 5 years ago

      The way to play LAN without steam or other programs:

      you look up your IP address.

      start mw2, press windows logo to go back to windows where you will see the IW window with all the mw2 data.

      you will see you can enter text, so you enter:

      connect localhost

      or

      connect (ip address of the host)

      go back to mw2 and you will be connected and you can have private matches or go online together with 2 or more pc's.

      its actually very simple but nobody seems to know this... (LOL)

      Lan does work! 5 years ago

      Just like you would connect in tunngle(either using the co-op starter or just right click the teknogod executable shortcut[on desktop], go to properties, add (space)--ip=(host computer's ipv4 address) at the end of the 'target' info)

      but put the hosting computers ipv4 address obtained from 'ipconfig'(of host computer) EX: 192.168.1.100 ....so with the short cut it would be

      ("D:\Intalled Games\Modern Warfare 2\TeknoGods_MW2SP.exe"[ --ip=192.168.1.100]) with the part in brackets added to the target parameters.

      then start host, choose game, start shortcut on other computer, press f12(sometimes 2x)...good luck and have fun, I know I am!
