XCOM: Enemy Unknown The Long War v.1.0

Description
Long War is a mod for XCOM: Enemy Unkown created by JohnnyLump oraz Amineri. This mod makes hundreds of changes, large and small, to the vanilla version of the game. It is harder and longer than the vanilla version but gives you many more tools to combat the alien threat.
Some of the changes in this mod include:An extended campaign requiring far more missions to completeTactical missions that allow up to twelve XCom soldiers per mission with the right upgradesEight soldier classes: Infantry, Assault, Sniper, Scout, Gunner, Rocketeer, Medic and Engineer, and eight MEC classes: Valkyrie, Marauder, Jaeger, Pathfinder, Goliath, Archer, Guardian and ShogunNew and modified perks, including Ranger, Sapper, HEAT Warheads, Lock N' Load and Javelin RocketsNew and modified technologies, including Xenopsionics, Alien Biocybernetics, Pulse Lasers, Gauss Weapons and Advanced Aerospace Concepts, and many new foundry projectsFive tiers of XCOM weaponry, many new armors and small items and S.H.I.V.s that can be equipped with perk-granting small items! See some of the new weapons here.Much earlier access to psionics and vastly expanded psionics treeA system of commissioning and promoting XCOM officers who provide bonuses to your entire squad during missions (replaces the Enemy Within medals system)Overhauled interception game, with five new UFO classes such as the Fighter, Raider and Harvester, as well as six interceptors per continent, foundry projects to upgrade your aircraft, individualized pilot names and pilot experience, and the Stingray Missile weapon systemOverhauled strategy game, in which the aliens gather resources and conduct research -- efforts XCOM must interdict if it hopes to save humanity. XCOM can now retake countries by finding and conquering alien bases in those countries. Help council countries defend themselves by fulfilling their requests for alien technology!Aliens and EXALT forces grow tougher over time, gaining stats and perksNew weapons for XCOM soldiersSoldiers rest after each mission, requiring the player to build a much deeper roster of soldiersModified Second Wave options to support longer campaignsMost of the specific changes will be detailed in in-game text. Many game mechanics have changed, so read perk, tech and item descriptions closely! They may not do what you expect from vanilla.Perk trees for all classes are in the file LW3pt.jpg in your XEW directory, or here.Tech tree is in the file LW3tt.jpg in your XEW directory, or here.A Long War wiki is hosted on UFOpeadia, here.

Installation:
If you are upgrading from Beta 3 or earlier, you should verify back to an up-to-date vanilla install.
Beta 10 requires a new campaign.

Instructions

If you have ever played 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 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 may receive a crash to desktop (CTD) error; this appears to be some aspect of the mod completing installation and then making nice with Steam. Start it again, 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.
We don't think it will work on Macs, although you are welcome to try and give us feedback.
The mod will not work properly on 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. 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.
