The Integral Update - Ground Zeroes Hard Mode

Fans of this mod: I've added more difficulties in addition to Ground Zeroes Hard. Check out Difficulty Select here

For those of us that played MGSV: Ground Zeroes and found that the Hard Mode was ultimate Metal Gear experience. I've tested and compared almost every difference between the Normal/Hard modes, and have ported those changes into The Phantom Pain

Similar to how MGS1 Integral added a new difficulty for players to enjoy, The Integral Update adds in the missing Ground Zeroes Hard Mode into The Phantom Pain

You will know this mod is enabled on the Sortie Prep Screen

Enemy Changes

-Enemy sight increased to GZ's sight: The major overhaul of this mod is updating the enemies's sight to match the enemies's sight in Ground Zeroes Hard Mode (See below for in-depth details)

-Enemy hearing: To my surprise, the enemies in GZ Hard Mode have the same hearing distance as those in Normal mode. So no update has been made to their hearing

-Camo penalty for Hard mode: Ground Zeroes Hard mode applies a universal camo penalty of -10. This actually makes correct camouflage necessary. An example. In vanilla TPP, lying on the ground during the day means enemies will not notice/discover you until they are 10M away. In Ground Zeroes hard mode, the camo penalty is applied and vision cones are extended.

This means lying on the ground during the day will result in enemies noticing you at 30M and discovering you at 15M.

Whereas having the correct camo while lying on the floor will have guards notice/discover at 15M.

-Sleep times decreased: Cut in half, from 5 minutes to 2m30s

-Dieing: 60 seconds to 30 seconds

Player Changes

-Player health decreased: 6000 / 3000

-Health recovery rate decreased: 1000 / 500

-Health recovery cooldown timer increased: 2secs / 6secs

-Optional Subsistence Primary/Secondary

Gaps in knowledge

-Differences in vision cone width/height

-How enemy accuracy is handled (they seem more accurate/aggressive in GZ Hard, but could find no references)

-Anything I missed. Please feel free to leave feedback if there's an aspect of Hard Mode I'm missing. This mod is an attempt to match GZ Hard as best as possible, so if it's not in GZ Hard mode, I will not add it to this mod.
