Something within its dark walls has awakened... -------- Requirements -------- Fallout 3 is the only requirement. DLC and FOSE are NOT required. -------- Compatibility -------- Mart\'s Mutant Mod: Compatible with merged patch. If you use MMM, it is advised that you use FO3edit to create a merged patch. If you do not, the mods will still work together, but you may see venomlurks (from Mantis.esp) completely replacing mirelurks, instead of occasionally appearing with them. FOOK2: Untested. No issues expected with Mantis.esp and Jello.esp. See issues for FWE below with balance modules, as similar compatibility issues will likely occur. FWE: Untested. No issues expected with Mantis.esp and Jello.esp. HOWEVER, make sure to disable any \"tougher stealth\" or similar components, as it can make one section of this mod quite difficult, if not impossible.

  • It is recommended that you DO NOT load Combat.esp, XP.esp, Skillbooks.esp, or Medical.esp in conjunction with FWE, as their alterations will conflict with each other and may cause issues.

Depending on your load order, you\'ll either be more likely to see Afro-Cola (if AfroSlayers loads after jello.esp) or more Jell-O (if Jello.esp loads after AfroSlayers) -------- Installation -------- Extract the contents of the zip file into your Fallout 3 Data Folder and be sure to place a check mark next to the new .esp files before launching the game.
