In this mod, when enabled, all mojave wasteland creatures (and some NPC`s), will be raised in heath points and level by almost 80%. This means that for lower level players (and even some capped level players), you might be having an extremely hard time killing the creatures. Deathclaws are now more scary than ever. One simple swipe can kill even a level 15 player. Also, robots are powered by Nuclear Energy. How else do you think they run? On a never ending battery? So now when killing robots: Beware. Some might explode. The bigger the robot, the bigger the explosion. Also, a few easter eggs have been placed in this mod. References to survival horror franchises like Resident Evil and Silent Hill can be found somewhere in the game with this mod. Can you find them? Installation: -Open your fallout NV install folder. -Find your DATA folder. -Place nightmare mode.esp in your data folder. -Launch the game launcher. -Go to DATA FILES. -Turn on "Nightmare.ESP", then launch the game.
