Current Version

Long War 3.0 Beta 14d Download


You must have a legitimate PC, Mac, or Linux version of XCOM and the Enemy Within DLC to play this mod. This mod is for games with the March 10, 2014, patch, what we're calling Enemy Within Patch 3. The game version is still listed as 401776.[1]



If you are upgrading from Long War Beta 3.0 or earlier, you should verify back to an up-to-date vanilla EW install. Moving from Beta 9 to Beta 10 requires a new campaign.

  • If you have ever played XCOM with any other mods on your EW install, or have changed some files yourself, verify back to a vanilla installation of EW before installing Long War. If you have any other trouble with installation, do this as well.
  • Disable any antivirus software. We have specific reports that Comodo security software prevents a proper install, and BitDefender free crashes the game on startup.
  • Make sure you have the latest .NET Framework and Java installed.
  • Run the installer.
  • When you select your path to install the mod, you should receive a warning that the directory already exists. If you didn't, have you may have missed a step.
  • Start the game once. You will most likely receive a crash to desktop (CTD) error; this appears to be some aspect of the mod completing installation and then making nice with Steam.
  • Restart and it should run.
  • If you have been playing vanilla XCOM in a language other than the one you installed it in, switch XCOM to the installed Long War language via its properties in Steam.

Installation Notes

  • This mod will overwrite several game files and likely render multiplayer unplayable until you uninstall.
  • The Mac and Linux versions are available via separate downloads.
  • The mod will not work properly on existing vanilla Enemy Within campaigns, so you'll need to start a new one. Campaigns are saved even if you uninstall, so you should be able to return to vanilla campaigns after uninstalling Long War. Long War campaigns probably won't work well in vanilla.
  • If Firaxis/2K Games issues any patches to vanilla XCOM, it will overwrite and disable Long War, and almost certainly make the mod unplayable until the modders are able to update it. Unfortunately, turning off automatic updates to the game in Steam, via the game's Steam Library Context Menu > Properties > Updates tab, does not prevent patches from loading. Your savegames should be preserved, though.
  • If you want to use alternate game textures via TexMod, install them AFTER you fully install Long War.
  • If you install this mod over an existing version you won't be able to uninstall back to vanilla; to do so, you'll have to go to Steam and use the Verify Integrity of Game Cache option (under the game's Steam Library Context Menu > Properties > Local Files tab) to restore your game to its original settings. You should also do this if something goes wrong with the uninstall.
  • On Beta 9a and earlier, if this is your first time playing Long War, you should hit Alt+F10 once at the beginning of the game (once the first mission is underway) to reset your map cycler. This will be done automatically when starting a new campaign in Beta 10 and afterward.
  • It is safe to assume that updating the mod will overwrite any changes you have made to the INI files. Best practices are to save your INI edits and re-insert (re-type) the changes each time you update
  • To uninstall Long War in Windows 7 and above, you need to navigate to your Windows Control Panel > Programs and Features > Uninstall or Change a Program, then double click on "Long War"


Bugfix List

Bug Reporting

To report a Bug follow these steps:

1) Be absolutely 100% certain that you are running the latest version of the Mod before you report a Bug. That version is currently Long War 3.0 Beta 14d

2) Check the list of all reported bugs and completed bug fixes for the current version here. A list of all bug fixes can be found here

3) If you are running the most current Beta version and you still have an issue follow the troubleshooting instructions from this webpage:

If you get multiple CTDs upon boot, or when starting the first mission, or you start with only four soldiers, or see graphical glitches with some of the new weapons, try the following steps:

  • Go to C:/Users/YOUR WINDOWS USERNAME/Documents/My Games/XCOM - Enemy Within/XComGame/Config
  • Delete all files in that directory.
  • Start the game and see if it works.
  • Go to C:/Program Files (x86)/Steam/SteamApps/common/XCom-Enemy-Unknown/XEW/XComGame/CookedPCConsole. (This may vary if you have a nontraditional Steam installation.)
  • Look for the files XComGame.upk.uncompressed_size and XComStrategyGame.upk.uncompressed_size. If they are present, delete them.
  • Start the game and see if it works.
  • If not, Go to C:/Users/YOUR WINDOWS USERNAME/Documents/My Games/XCOM - Enemy Within/XComGame/SaveData
  • Delete or rename the file profile.bin and start the game. You may have to re-set your graphics and other settings ingame after this.
  • Start the game and see if it works.
  • Install Long War EW again, over the current copy. This will probably make the included uninstaller not work, so you'll have to verify back to vanilla via Steam to uninstall.

If you are getting slowdowns in plays or CTDs when loading user settings, try the following:

  • Delete old savegames you aren't using anymore
  • Turn off cloud synchronization of your saves
  • Play in offline mode

4) Before you submit your bug make sure that you have an Autosave file showing the issue, that can be used by the Devs to replicate your issue.

5) To submit a bug you must provide detailed feedback to the Long War EW Beta feedback forum here. Make sure that you post the following:

  • Your difficulty level
  • Any Second Wave options you are using
  • Any modifications that you made to the INI files
  • Any other mods you are running in addition to LW
  • And whether you started a campaign under this version, or a prior one.
  • A link to your uploaded save file

If you have a CTD, please follow the instructions in the readme for reporting crash logs to us.
