It's widely agreed that Fallout's Over-Encumbered mechanic is terrible. If you pickup 1 gram too much, suddenly you can't run or fast travel, and you're forced to drop something to be able to move again. The penalty here is taking the game's most boring mechanic (movement) and making it even more boring. This is just bad game design, particularly in an open world game where you can just come back for things later. It doesn't force the player to choose between one thing and another, it just forces the player to waste time.

This mod is designed to be played in survival mode. It works in non-survival modes, but you won't get the full experience.

Mod Features

- Over Encumbered

• You can run while encumbered, but it drains your AP. Holstering your weapon reduces the AP Drain by half.
• Larger weapon types (rifles, 2 handed melee, and especially heavy guns) increase AP drain while encumbered.
• In survival, you take periodic health damage (but no limb damage)
  

Being over-encumbered out of combat is annoying but manageable (especially with a backpack), however drawing your weapon and running around drains your AP fast. This makes encumbrance more of a manageable, calculated risk. Do you travel light, and at full combat effectiveness, or do you grab everything, and avoid conflict?

- Base Carry Weight Scales non-linearly with Strength (with or without a backpack)

Base of 125 in Normal, 25 in Survival plus

• Str 1-5 : 15 points per rank
• Str 6-10: 10 points per rank
• Str 11-15: 5 points per rank
  

Player carry weight is nerfed, however being able to run means that encumbrance is manageable - you will frequently be over-encumbered, but it won't slow down the pace of the game as much if you have a backpack (however it will make combat more challenging). The non-linear strength scaling also makes str buffing equipment and consumables much more valuable for players with low str. Example: A player with str 6 will have 25 + 5x15 + 1x10 carry weight.

- Backpacks come in 3 main Flavours
They all increase your carry weight, reduce the AP drain while your weapon is holstered, and may reduce your encumbered run speed

• Satchels: +15 Carry Weight, AP Drain reduced to 90%,
• Light Backpacks: +30 Carry Weight, AP Drain reduced to 50%, and 10% reduced run speed while encumbered
• Heavy Backpacks: +10 Carry Weight per Strength, AP Drain reduced to 10%, and 20% reduced run speed while encumbered
  

Satchels are great for players who don't want to spend much time encumbered, but the decreased AP Drain with your weapon holstered found on heavier backpacks makes traveling long distances significantly smoother.

- Pocketed Armor Mods are disabled
Backpacks are the primary carry weight mechanic, and lightweight armor mods reduce weight on armor.

- Strong Back

• +25 Carry Weight
• 25% reduced AP drain while encumbered
• +50 Carry Weigh
• 50% reduced AP drain while encumbered
• You can fast travel while over-encumbered, or no longer take periodic damage when over-encumbered in survival.
  

- Companions Aren't Your Sherpa's
Companion carry weight has been reduced to a flat 35
Companions do not benefit from backpacks.

Because the over-encumbered status is now pretty manageable, your companions expect you to carry your own crap back to camp.

Installation

• Installing this mod requires a new game - there is some sort of carry weight calculation that occurs in a new game that there doesn't seem to be a workaround for.
• Download and install the main mod from here.
• Download and install patches for the backpack mods you're using. Note: this mod does not actually include any backpacks, it's a framework, intended to be used with the backpack mods of your choice.
  
  
  

Known Issues
- When you first load the game, you will get a "You are encumbered, running will drain your AP" message. This is the result of a workaround I put in place to avoid the vanilla survival carry weight bug on companions. It takes a second for the mod's effects to kick in and recalculate carry weight.
- Companion carry weight is SUPER janky. I've done what I can, but honestly I recommend simply not using companions to carry stuff. If you find particular companions that you cannot add stuff too, it's usaully their hidden companion weapon- which, super annoyingly, actually has hidden weight. Either use modav carryweight console commands to just bump their weight, or set the companion weapon weight to zero using fo4edit.
