📋 About This Mod

READ FIRST This mod requires Broken Steel DLC. This mod also uses a number of JQ\'s meshes. Most of JQ\'s meshes can be acquired from Coffagenesis\'s 40k Enclave Commander mod: http://www.fallout3nexus.com/downloads/file.php?id=5579. Placeholders are included for the Power Axe and Heavy Bolter, which are not included in the 40k Enclave Commander mod. This mod includes custom races: Eldar, Tau and Necron. I recommend using this mod if you plan on playing as one of those custom races: http://fallout3nexus.com/downloads/file.php?id=6240. Otherwise your game might freeze during the transition to Broken Steel or Mothership Zeta. Also, I advise caution when updating, because updates may be incompatible with pre-existing saved games. Finally, feel free to upload your own screenshots. Kudos will be given. ---Contents--- 1. 0 Installation 2. 0 Purpose 2. 1 About 40k 3. 0 Plug-ins 3. 1 Main Files 3. 2 Faction Plugins 3. 3 WI-Commander (Also how to change chapters) 3. 4 Supplemental Plug-ins 3. 5 Increased Spawns Plug-ins 4. 0 Bugs and Compatibility 5. 0 Known Issues 6. 0 Additional Mods 7. 0 Future Plans 8. 0 File Credits 9. 0 Change Log ----------------- 1. 0 Installation ----------------- Download and unzip all .rar files in the \'Main\' and \'Updates\' categories into your Fallout 3 \"Data\" Directory. Once you have these files installed, use your Fallout 3 Launcher or Fallout Mod Manager (http://fallout3nexus.com/downloads/file.php?id=640) to activate Warhammer-Integrated-BS-Base.esp and any accompanying files you want to use. For more information on plug-ins, check the documentation text file labeled \'Plug-ins and MMM Compatibility\' or go down to Section 3. If textures are not loading correctly, you probably need to toggle Archive Invalidation (http://fallout3nexus.com/downloads/file.php?id=944). If you have already toggled Archive Invalidation and if only certain textures are missing, not all of them, there are three possibilities: 1. You did not download ALL of the necessary files. 2. Your Fallout 3 game is installed to a directory other than C:/Program Files/Bethesda Softworks/Fallout 3. This can cause errors with certain textures missing. Please inform me if this is the case. 3. I screwed up. The number of files in the archives is massive and sometimes assets get left out. Please inform me of any meshes or textures that are misbehaving. The more information you give me, the faster I can fix the issue. Finally, you may also need to use the Fallout Script Extender in order for this mod to work (http://fose.silverlock.org/). I do not know this for certain because I have never tested this mod without FOSE. ------------ 2. 0 Purpose ------------ This mod is unique among the 40k Fallout 3 conversions, and rare among most computer games that involve the 40k franchise, in that it allows you to play not only as the Space Marines but also as Imperial Guard, Chaos, Tau, Eldar, Dark Eld
