In the field
In the vanilla game after not coming to mother base for a long time, your health drops by 10% and the reflex mode is shorter.
These "consequences" are hardly noticeable and don't have almost any impact on the gameplay. This mod aims to fix that.

Features
There are 4 exhaustion levels: Refreshed, Tired, Very Tired and Exhausted.

Refreshed (from 0 - 1 days without going back to MB) - nothing happens.

Tired (from 1-2 days without going back to MB) - user markers stop displaying in the world, Snake moves at 90% of his normal speed.

Very Tired (from 2-3 days without going back to MB) - user markers stop displaying in the world, markers above enemies, vehicles, mortars, etc. stop displaying in the world, Snake moves at 80% of his normal speed.

Exhausted (from 3- days without going back to MB) - user markers stop displaying in the world, markers above enemies, vehicles, mortars, etc. stop displaying in the world, Snake moves at 70% of his normal speed.

Status - it can be checked by pressing "reload" while in a carboard box.

Warning
Making Snake slower is still an experimental feature (it works but there may be some bugs). This feature also requires turning off Reflex Mode in the game, otherwise it WILL break when spotted by the enemy. There is an option to download the mod without the feature so that you can use it with Reflex Mode.
This feature is fully implemented now and it doesn't break the game with reflex mode on.
