Description of MechWarrior 4: Mercenaries

MechWarrior 4: Mercenaries is a classic “BattleTech” simulation developed by FASA and published by Microsoft in 2002 and re-published in 2010 by MekTek as a free download. Eventually MekTek decided to separate from the franchise.

With the inclusion of Inner Sphere, Clan and MekTek packs, the game gained a huge following. Like its predecessors, it is first person aspect within a “Mech” cockpit. Controls are detailed with the ability customize for gaming comfort. The graphics are solid for the time period. It is best played with a joystick. A game pad will work, but it is not as much fun. Online play was a huge factor and many “clans” participated in online matches. An entire gaming universe was created with the advent of the Astral Dominion League. Clans could win resources, planets and fight for the honor of their clan.

The Story: It’s the year 3066 and you are a MechWarrior for hire. In a galaxy embroiled in war you find your loyalties lie with the highest bidder. Will you fight for House Davion, House Steiner or will you let your bank account decide? As a mercenary you will need to manage your finances, buy, sell and equip your “Mechs”. Nothing is cheap and everything costs you money. Want to make some fast cash? Try your luck on Solaris and see if you can rise to the top of the Solaris Tournament ranks. Here you will, run fight, make temporary alliances and then stab them in the back!

Hey, it’s about the money. In the end will you be rich or broke? It’s a merc’s life.

MechWarrior 4: Mercenaries has the following addons available: MechWarrior 4: Inner Sphere 'Mech Pak and MechWarrior 4: Clan 'Mech Pak, don't miss them!

I got this going fine on Windows 10 BUT I can only play the game in one resolution! I tried compatibility settings, but if i play full screen, its a tiny little square in middle of screen, if i play windowed its much bigger but mouse cursor keeps going off screen. Any widescreen fix please? If you help me, leave your email ill send you a few free GoG codes or sumtin?

Puggles2G 2022-10-08 12 points

I really love all these old games and I am glad that you are saving them for future generations. Please let me know if you have any jobs I can do. I would be glad to work for free! I just want to help save all of these old games.

Mr Dred 2022-07-30 1 point

The archive link from Zool's post is the one. No install portable, IS pack, Clan pack, latest MekTek community pack adding many mechs and elementals. Too bad the server is defunct, you could set one up altering the IP in the database i guess, its still good for LAN though (even if its set up with a VPN). All expansion pack mechs are multiplayer ONLY. This is the best Battletech sim there is and this file is most current version. Ancient by today's standards, still a real gem.

Also, I suggest the mektek download as it's the final version of the game and doesn't need a no cd crack as it uses windows direct play.

I love the game. My org disks will not work with window 10 / 11 , . tried to use the compatibility options for XP. no go. So I will give this a try. Thanks.

i really need help to install this

Ded Spector 2021-10-12 -1 point

Dayum, I had so much fun with this game. Though I frankly prefer Mechcommander 2 in hindsight.

Trying to beat the game in hardmode was impossible for me. Would require waaay too much jump-sniping at max range, on top of reloading saves to avoid gamebreaking bugs. E.g. sometimes, enemies would randomly sink 2 Kilometres into the ground, making the mission unbeatable. Or escorts getting stuck and refusing to move.

I also played the Mektek version, but back then it still required a CD check with the original MW4: Mercs CD, which made it rather annoying since I was playing it with a NoCD hack that was easy as pie to find and install.

Also the Mektek version locked out the new fan-made weapons and Mechs from the solo Campaign game... UNLESS you did some additional hacking to put them in, which was a lot more tedious and not simple at all.

Tankuality 2021-02-19 1 point

forgot to mention, it also seems to be missing the rifleman

Tankuality 2021-02-19 1 point

It's a technical nightmare to set up, thats just how the game is, not compatible by default with modern tech, but it seems to run fine, although, i AM missing a few mechs(archer, marauder, marauder 2, warhammer, wasp, battle cobra, linebacker) but overall it works well(by the way, the instructions for how to install it here need updated, since it's not that simple to install it anymore)

Screen resolution 2021-02-04 -3 points

I want to play 1024x678 or better, since I have a NV GTX video card, but auto config at at setting above medium only gives me part of the screen not all of it. Yes I have the mek tek version but I would like full width screen, not this full screen with bars on the side like an old tv.

Arkten 2020-06-25 2 points

This is by far the most comprehensive and effective guide I've found for installing all the MW4 variants. I thoroughly encourage you follow this link as it includes detailed win 10 instructions and various things like patches. 1 thing though, there's a line telling you to go to a at the beginning, replace that w/the name of the mektek download. Also, I suggest the mektek download as it's the final version of the game and doesn't need a no cd crack as it uses windows direct play.

Hi Virtue, why don't you try firefox ?

FOMO 2020-04-13 0 point

I miss these old FASA Microsoft battletech games. I really liked the video cutscenes at the start of the games and the music was great in all of the games too. Sort of indutrial rock vibe to it all and when it was kicking off the music really added to all the action happening around you. Quality voice acting too and variety in the missions which were also quite long with objectives suddenly changing as things happened within the game. In fact has everything the current Mechwarrior 5 is missing now.. even graphically it's not much worse then the current offering by Pirahna (aka Mechwarrior Online fame). MW5 plays way too much like it's online cousin and much of what made the MW great seems to be missin gin the latest game. Give the license back to them! lol.

Mechfan 2020-04-01 1 point

Like quite a few on this forum i had problems running the original Mechwarrior games discs on win 10.
Installing itself was not a problem, it would happen after pressing the games icons in desktop. So what has worked - for me today (1/4/2020 - is downloading and running the Mek Tek version from this site.
Just follow a previous instruction from a post below: I'll repeat here.
Download Met Tek Version. Unzip the file to chosen drive (should come up automatically)
C:MW4mercs...etc Open folder and look for "Auto config_Mercs.exe" It's about halfway down the files, then select the card and graphics settings (it should pop up) since it's an old game you can set everything to max set resolution to 1024x768 - there's a choice of three - Find the "MW4mercs.exe "line again to create a shortcut, go to properties on shortcut and select "run in admin mode.
Just one problem ( least for me) it won't run from the shortcut, there's an error that says: "missing language Dll" i have to keep opening the game from the exe.file in the games folder....but hey, the game runs and works.

Hope this helps.

Walshmeister_88803 2020-03-23 -1 point

I followed an easy guide youtube video and downloaded all the Mech4 games and set them up properly with Voodoo support and both Mech4 Vengeance and Black Knight work perfectly but for some reason Mech4 Mercs still says it needs a disk 2. Can someone help me find a way to bypass it? It did with the Mettak download and did it with the Original download and I did the steps like with Vengeance properly and also with the NODC HOTFIX download witch I believe was required for the Original. I would like a response on this issue because I really want to play with the new toys.

For those who don't wish to go through the hassle of fighting through the above steps, load a no cd patch and have HD game play, then DL the game here:
this is an installer and installs to version 3.1.093.
Mods may want to host this file here

10021k 2019-12-21 2 points

I got one way to get it to work on Windows 10 64 bit newest version.

1. Download the original ISO

2. Extract the ISO's in the zip

3. In the search box in windows type "Powershell"

4. In the shell type Mount-DiskImage -ImagePath or just copy and paste and drag the ISO to the Powershell

5. Now type in search bar " Thispc "

6. right-click on the mech warrior cd drive and hit explore

7. click install and let it install and go through it.

8. When it asks for 2nd cd of that drive letter. go back into this pc and click eject on
the mech warrior cd.

9. go back into Powershell and push the up arrow key and replace the one with a two
in the file. and click enter and wait for it to mount.

10. go into search box again and type Disc management and click on "create and format disk partitions"

11. right-click the Mechwarrior second cd and click change drive letter and paths
and click change. also make it the first driver letter to whatever it was example D:\, f:\, H:\

12. continue installing

13. after you are done install the no-cd file on this site and extract it. Copy and replace the EXE with the new one the installation directory should be
C:\Program Files (x86)\Microsoft Games\Mechwarrior Mercenaries.
and overwrite the file. you could copy and back up the original one.

Hope this helps and is clear :)

Vanguard 2019-11-23 0 point

I did everything on the steps, and even dowloaded DirectX 9 and enabled DirectPlay. However, when I go to run the program, no matter how im running it (whether its admin or regular), I always get this message:

The procedure * could not be located in the DLL mtshellmq.dll.

I try to open said file and it wont work. Is there a way to fix this?

Great game, it was the first and one of the only that I became really involved with from a multiplayer standpoint (PR1).

to all from those days, I'm glad the community is still alive and well! I might have to load it up again when I have some time. :)

on behalf of Ar'Kel too. (RIP brother). :(

I do not have step 2. Can someone please help me?

OldGamerGuy 2019-05-28 2 points

I'm trying to unzip and run a game using Windows 7. The game ran on an earlier version of Windows. gives these instructions
1 Download MekTek Version.
2 Unzip the file to your chosen drive. C:\MW4Mercs etc.
3 Open folder and run under admin mode “autoconfig_MERCS.exe”
4 Select your video card and graphics setting.
5 Find MW4Mercs.exe and make a shortcut on your desktop.
6 Run in admin mode.

First I downloaded the program named 7Zip
I am not sure if I correctly unzipped the file.

Within the game, there is a Tab for setting Video, but the Screen Resolution drop down button does not do anything

I reached all the way to step six, but the game launches to a black screen
and I get an error message: STOP: You do not have the correct video codec installed to play Content\Movies\mektek_mekpak31_logo.mpeg

It then gives choice buttons: More Details, Continue, Exit

When I choose Continue, the game appears to launch, but the screen is completely black and there is no sound. I may not be waiting long enough.

Sometimes when I click a few times with my mouse, an animated mouse cursor for the game appears on the black screen.

sometimes the black screen then shirnks to about one fourth of my monitor screen, and it appears to be the whole game, but music stutters a bit.

I try to select the option to go full screen, but then, it crashes to black screen again, and I get:

Fatal Error Nested exception - Cause: EnterWindowMode.

Error: You do not have the correct video codec installed to play
Content\Movies\mektek_mekpak31_logo.mpeg at 0x0

The Minimize button works fine, it just won't enlarge to full screen

I did all those methods, still doesn't work, same problems.
Maybe make new patch or new update for this game?

blahblahblacksheep 2019-04-26 1 point

If you have Windows use a DPI / Text Scaling setting other then 100%, you'll notice all the MW4 games having an offset screen that seems to be shifted to the lower-right, leaving a black bar on the top, regardless of game screen resolution. (The main menu will look fine, but once you start a mission, like training, the screen has a black bar on top, and hitting ESC has the menu shoved down in the lower right corner.. it's still centered on the game screen, but the game screen is offset from your monitor).

Reason... The MW4 games use fonts (eg: for menus) that are impacted by the Windows DPI / Text Scaling setting. You may have changed the DPI / Text Scaling in order to keep a high resolution (eg 1080) but to scale the fonts up in size so you could read them instead of them looking super small.

You can double-check your DPI / Text Scaling in Win 10 by...

1) right-click desktop
2) Display Settings
3) Change size of text, apps and other items

If it's set to anything higher then 100%, it can cause issues in MW4.

The Work-Around...

1) Right-click the MW4 shortcut on your desktop
2) Properties
3) (tab) Compatability
4) (button) Change High DPI Settings
5) (checkbox) Override high DPI Scaling
6) (dropdown .. Scaling Performed By) Application

This will let the Application use whatever DPI / Text Scaling it wants (basically make it use 100% w/o you having to manually set that in the Windows Display Settings.)

Do this to all the shortcuts for the MW4 games you've installed: Vengeance, Black Knight, Mercenaries

Hi all, This was one I never played much and excited to have it working with Win 7. I am having issues figuring out a way to get it in 1080. Mainly because I want to record it. Not finding any good instruction on this. Thanks all ahead of time.

DasAntihero 2018-11-26 1 point

A great game, and my favorite in the series next to MechWarrior 3. Though, unlike 3 this game takes less effort to get working on Windows newer than 98/XP, and you can have a nice WSAD setup with this, too!

RoboMunky 2018-01-28 -21 points

"No CD fix" doesn't work, as the problem seems to prevent complete installation. Obviously, I'm wasting my time with this site, as no useful fix seems to be available for the defective software purveyed.

Chralex 2018-01-11 1 point

I had issues running my original copy on windows 10, it did not matter what I did to the installed EXE file it just crashed on start, using the no CD-fix apparently worked for me. You basically just replace the original "MW4Mercs.exe" file in the install directory with the one downloaded in the "no CD fix".

Do note that I already had DirectPlay enabled, I did not need to start it as administrator, and I had run the auto-config tool prior to launching it.

I think that as a kid I played through the game three times, but it seems like I've always taken the Davion path, this time I'm going Steiner and I'm playing missions that I don't even remember, so there was something to come back to.

Installed on Windows 10 with the 2 .iso disks. Goto play and it keeps asking to insert correct cd-rom and restart the program. How do I fix.

Diablo A Wolff 2017-11-09 -2 points

I've played this game for many years using the original disc. The disc has developed reading problems that cannot be repaired. I suspect scratches or nicks in the disk. What I have noticed from several attempts to download the game from various websites is the executable file has a virus (Trojan.Gen2) that has been there for over nine years. Most of the virus catchers will catch it and allow it to be exempted. Windows 10 version 107 does not allow it, and deletes it entirely. Even the .rar files will get hit if they are in the download folder. I'm hoping the files from this website are clean and playable. The buggiest downloads were from Clan Coyote's downloads. I informed the WEB master, but have not received a reply yet. Beware.

How do I install the Mektek version on windows 10?

Lentulus Batiatus 2017-07-26 3 points

Some notes:
-Mektek version gives you tons more mechs and includes the original content with minimal modifications and slightly better performance. By far the version to grab.
-For the above version, MW4Mercs.exe launches the game.
-You can unpack it anywhere. Heck, you could run it straight off a USB stick and carry that around... and the game isn't too intensive to worry much about the performance implications of that.
-For windows 10 users, I suggest a run through the compatibility troubleshooter if you have issues.

I've found that any bugs with this game are variable based on what other contents you have on your system, such as driver quirks or other programs. The operating system does not make or break MW4 as I have played it on Windows XP, Vista, 7 and 10 without issues.

Saleem Yogi 2017-07-17 -1 point

I have been playing this game since it started. I even got my son started on this game. This is one awesome game. Please make it compatible with the newer platforms. Y'all will make tons of money and we will have an awesome game to speed throughout the web. The games today that are knockoffs can't come close to the original.

I need them mounted virtually onto my PC to install mechwarrior4. My old computer works with them, but my new one doesn't, and also a problem I found on my old PC, it tells me to insert disc 2 onto E: which is the first one, moving it or pasting it into the first one cant work because no space. Probaly did it wrong, but I dont know anything!

When even I launch the game I get a message saying I don't have minimum specs, or if i do get into the game, the graphics glitch out at the menu, where I promptly close the program. Any hints?

Just a tip-- once you have a 'Mech with 3 critical beam/omni slots and enough tonnage, make sure to equip at least one ER PPC. They're lightweight (6-7 tons), have no ammo cost, and can remove almost a ton of armor in a single shot. The only downside is that they generate a LOT of heat, so make sure to save room for a few heat sinks. I typically outfit a Daishi with 2 ER PPC's, an MRM-30, 2 Small Pulse Lasers, and 2 Large Pulse Lasers, saving the rest of the tonnage for missile ammo, armor, heat sinks, and engine power.

@ the48thronin I have win7 64 bit and works fine.
-I downloaded the mektek version
-I used WinRAR to unzip it
-then I played it, no problems.
so try the WinRAR program.

The48thRonin 2016-06-15 -2 points

Alright, I'm running Win7 64 and I have managed to install the game with VirtualClone but when I try to run the game all I get is a error message stating the program has stopped running. I've tried running in compatibility mode but no dice.

Aiden 2016-05-14 1 point


I had the same problem, I uninstalled the program and reinstalled it and still the same thing. I'm going to try running it in compatibility mode and see if that fixes it. I'd suggest that as well.

@ foster, hey bro can you be a bit more specific about your problem?
if I had to guess I would say you are missing the WinRAR program or
some other program to let you UNZIP the downloaded file.

esf345 2016-04-26 0 point

the mektek version for download is an updated game engine and high quality textures along with both mechpaks which both come with the original mechs when they came out and mechs made by some people at mektek inc., even though everything is the same as back when it became free on the mektek site the only problem is you cant have the resolution fit to your monitor as there are only 3 choices 1024x768, 800x600, and 640x480.

Murderkai 2016-04-23 0 point

I was 5 when I used to play this back in 2008-ish on an old shoddy PC.
The disc was in there when it died so we abandoned it to rot in our garage forgetting about the disc. Now it's 2016 and i'm 12.
For the last month I had been searching the entire house for MW4 since I really wanted to experience the nostalgia again, forgetting it was in the old PC. I then realised last night it was still in the PC. I unscrewed the PC and opened the disc compartment. There it was!
It was the most excited i've been int the last 2 years.
I loaded it into my new PC and installed it. After about 10 minutes it finished.
It was th most disappointed i've been in the last 2 years.
'Installation Successful, Please Insert Disc 2'

Murderkai 2016-04-23 -1 point

Used to play this when I was 5 on an old MSI computer in 2009. Wow 60GB of hardrive it was amazing. Then the computers capacitors died and we could no longer play it so we abandoned it and left it in our garage. Now it's 2016 and i'm 12. I wanted to play MW4 so I searched the entire house instead of the garage. I was really disappointed after looking for it for a solid week. 1 month later I remembered it was still in the old PC. I looked there, unscrewed the PC and found the disc. I was so excited. Put it into my desktop and installed it. Then I was the most disappointed i've ever been in my entire life. It said 'Installation Complete... Insert Disc 2' FFFFUUUUUUUUUCCCCCCCCKKKKKKKKKKKKK

Just unpack the downloaded file. (you can use a plethora of free software, such as 7-zip) and then put the unpacked folder to the location you need, (program files?) and then when you want to play, start the MW4Mercs.exe that's in the "base" folder.

Bishop 2014-10-07 0 point Windows version

When ig88 said "the h-word" or "the d-word" he meant expletives. swear-words.unclean language. The h and d represent the first letter of such words. Which some try to avoid. This game and it's predecessors are well made and I would recommend playing them, although with caution due to the concerns voiced by ig88.

tforsaken 2014-10-06 -1 point Windows version

ig88 can i have some of what your taking what the fuck is the h word?

FB 2014-10-01 -1 point Windows version

What's the "d-word"? What's the "H-word"? Your short review would make a lot more sense to me if I knew what you're talking about. Drosophilia? Hamartophobia? Who knows?

ig88 2014-09-30 2 points Windows version

this game is very well done. the only 2 problems are it has use of the "d-word" in some of the levels and some of the mech names have the "h-word" in them. for the missions, my sugjestion is to turn of the sound and listen to some good techno instead. for the mech names, there is not much youcan do. this game for windos xp, not dos, but it works on windos seven also. somepeapol say it is not abandone ware, but it is nolonger sold by the original company and so i would not wory about it. all in all, I rait it 4 out of 5.

Ash 2014-07-14 0 point Windows version

This game was simply superb, it's got everything you'd want in a good mech game, a good degree of customization, and decent enough AI (Both ally and enemy), the game would probably be sold for $20 on GoG if it weren't for legal disputes with MegaMek, which btw, this version is the MegaMek version, which adds an additional 60 or so mechs to pilot! If you have the original, this is pretty much the Deluxe Edition, must have.

keppelectic 2014-06-21 0 point Windows version

I have an original copy of this game. When i installed the original, AVG notified me of a Trojan, which i removed and there were no problems at all for me. If anyone is receiving this it might just be an outdated file or so forth. Whilst i have an original, having a 2 year old rub it along the tile floor makes a difference to the install. This copy worked fine for me and i am running Windows 7 - 64 bit, just downloaded and opened MW4Mercs.exe and has been great since then. Still the best Mechwarrior you will ever play!

@{CYT}™Cmeg 2014-06-04 0 point Windows version

This IS a playable version of MW4 v3.1 (it IS 3.1 isn't it? TBQH I can't remember). Why should we all go emailing you? How do we know your not going to lump us with an MW4 vPasswordStealKeylogger eh?
Might be worth asking around "" (the only MW4 forum/site left on the whole net) if they know bout this!

@Disapointed 2014-06-04 0 point Windows version

I've been playing this download of MW4 for a few months, and not noticed any kind of virus troubles. None of my AV's detect anything. But, now you mention it, I'm sure I've heard other people mention finding this trojan. AFAIK it is a false alarm - it must have some code that has some similarities to one of the well known trojans, and perhaps some cheaper / freeware scanners LQ heuristics misidentify it.

the most important file in this whole download is affected with a virus. specifically MW4Mercs.exe, and the name of the virus is TROJ_SPNR.0BF412. This sucks, I've literally tried so many websites and I just want to play this game already. well I guess I'll just enjoy it through youtube videos.

Asso 2014-05-24 0 point Windows version

Though the game works fine, one niggle, if you want to make your own maps using the map creator tool provided - you're stuffed! There is a file missing in this installation - "tctd.exe" - without it the map creator simply won't work - and it is impossible to find this file anywhere else on the net.

The whole series of Mechwarrrior is timeless. This was the last one and still holds up incredibly well 12 years later. The stand alone Mercenaries series of both 2 and 4 had more to offer than the originals. Lots of options and incredible replat value

You can't use this by dragging the zip file over to the dos box. You have to add manually and it has to be a windows profile through d-fend reloaded, not a dosbox profile. You have to navigate into the "base folder" inside the mechwarrior 4 folder and find your exe file. Good luck.
