No% is a mod for the campaign portion of Alien: Isolation. The mod removes the flashlight, motion tracker, revolver, shotgun, flamethrower, bolt gun, stun baton, and the ability to pick up loot, blueprints, or swing the maintenance jack. In other words, the player gets absolutely nothing to use for the entirety of the game. Any in-game requirement to pick up the aforementioned weapons and gear in order to progress is either circumvented entirely, or the pickup animation simply doesn't give the player the item in question. A few small changes were made to the game in order to make it possible to complete, namely the removal of all facehuggers directly in the player's path, and the ability for the fire from the gas divert in Mission 12 to kill the Working Joes and allow the player to obtain the keycard required for progression. Some additional changes were also made to remove some of the more tedious portions of the game.

A full list of the changes can be found below:

  • New intro video.
  • New main menu title logo.
  • Amanda is unable to pick up loot.
  • All blueprint pickups are deactivated.
  • Amanda is able to run in Mission 1.
  • Mission 2 is significantly shortened to prevent flashlight pickup and maintenance jack swing unlock.
  • Revolver removed and keycard pickup activated in Mission 3.
  • Motion tracker removed and adjacent door unlocked in Mission 4.
  • Stun baton removed and door unlocked in Mission 6.
  • Mission 9 is significantly shortened. 
  • Amanda is not given a flamethrower after the pickup animation in Mission 10.
  • Amanda is not given a shotgun after the pickup animation in Mission 11.
  • The fire from the gas divert kills the Working Joes in Mission 12.
  • Amanda is not given a boltgun after the pickup animation in Mission 14.
  • Amanda is not given a revolver or shotgun after the pickup animation in Mission 14.
  • Both flamethrowers removed and the Alpha keyboard activated in the nest portion of Mission 14.
  • All non-egg facehuggers removed in the nest portion of Mission 14.
  • Facehugger removed from the Anesidora portion of Mission 15.
  • Amanda can run during the spacewalk portion of Mission 16.
  • Both facehuggers removed from Mission 17.
  • Amanda can run during the spacewalk portion of Mission 18.

  • Two aliens during the Tech Hub portion of Mission 4.
  • Two aliens in Mission 5.
  • Two aliens in Mission 7.
  • Additional save station added in the stairwell of the Lorenz potion of Mission 10.
  • Three aliens during the Lorenz potion of Mission 10: two initially, and a third once the Server Hub is reached.
  • Two aliens in the Gemini portion of Mission 10.
  • Two aliens at all times in the nest portion of Mission 14.
  • Three aliens in the first area of Mission 18: two initially, and a third from a scripted event.

To install this mod, follow one of the sets of instructions below depending on how you want to play:

Without Multiple Aliens:

Open the Base Mod (Required) folder and extract the DATA folder into "Program Files\Epic Games\AlienIsolation." Overwrite the files when prompted. If you just want to play the base game with the No% changes, stop here. If you would also like to remove the scripted damage in Mission 6, next open the No Scripted Damage Patch For Base Mod (Optional) folder and extract the DATA folder into "Program Files\Epic Games\AlienIsolation." Overwrite the files when prompted.

With Multiple Aliens:

Open the Base Mod (Required) folder and extract the DATA folder into "Program Files\Epic Games\AlienIsolation." Overwrite the files when prompted. Next, open the Multiple Aliens Patch (Optional) folder and extract the DATA folder into "Program Files\Epic Games\AlienIsolation." Overwrite the files when prompted. If you just want to play the base game with the No% changes and multiple aliens, stop here. If you would also like to remove the scripted damage in Mission 6, next open the No Scripted Damage Patch For Multiple Aliens (Optional) folder and extract the DATA folder into "Program Files\Epic Games\AlienIsolation." Overwrite the files when prompted.

To uninstall the mod and return your game to normal, simply click on the three dots below Alien: Isolation in your Epic Games library and select verify. The Epic Games Launcher will now redownload the necessary files to restore your game to the vanilla version. Please note that you must also restart the game from the beginning in order to no longer have extra aliens if you were playing with the multiple aliens patch, as the extra aliens are now tied to the mission saves you created while playing the mod.

NOTE: It is highly recommended to avoid taking any damage prior to the reactor core section of Mission 14, especially if you did not remove the scripted damage in Mission 6. While it's possible to get through the Heavy Joes on the way to the nest without being grabbed, it can be somewhat difficult. It is best to enter this part of the game with as much health as possible so that you can take a grab and a punch to get through them if needed. Also, remember to activate the gas divert in Mission 12 to kill the Working Joes so that you can obtain the keycard.
