📋 About This Mod
Welcome to Perk up.
This is part of the "Made for Fusion" series of mods, that are designed to be modular so you can install them on their own or all be combined together to eventually form a complete overhaul of the games mechanics and textures without straying too far from the vanilla ethos.
The current series line up:
-
[]Perk Up - Rehaul and fixes for various vanilla perks
[
]Capped Out - A small overhaul of the games levelled lists[]Targeted Textures - A select improvement of texture issues in the vanilla game
[]Perennial Power Armor - Rebalancing of vanilla power armour mechanics and levelled lists
[]Streamlined Weapons - A full rebalance of the games weapons and attachments
[]Consistent Combat - Lightweight combat related overhaul
Lets get into what this mod does and if it is for you. All perks have retained their names and core of what they were trying to achieve in vanilla.
Almost all perks that gave a flat additive buff or damage reduction have been changed to be percentage based instead, as this scales much better.
Not all perks have been changed, in particular the ones pertaining to crafting (Armorer, Gun nut, Science) This is to maintain compatibility with mods that have their levels as requirements and they worked fine in the game.
I will now list changes by perk:
Perk Tree
Adamantium Skeleton
Now reduces fall damage along with limb damage and explosive resistance up to a maximum of 90% at level 3
Forwarded fixes used in CFM and buffed the damage.
Better Criticals
Nerfed across the board. Now +25/50/100% instead of 50/100/150
Cannibal (Now a rank 3 perk)
Now acts as a food source rather that a buggy half implemented gameplay mechanic. Also affects hunger if you play on survival now as well.
Caps Collector
Nerfs rank 1 but buffs rank 2 and 3 slightly in regards to item discounts and prices.
Chem Resistant 2
Changed from complete immunity to addiction, to a 20% damage reduction whilst under the effects of chems.
Gunslinger, Rifleman and Commando.
Now all can affect each other. So for example in the base game if you had a laser sniper rifle, It would benefit from the rifleman perk. If you then changed it to an automatic it would lose that buff and be influenced by the commando perk instead. Now that's fine if automatic receivers were on par with their semi auto counterparts but they are not. The only good balanced way I have seen this implemented Is to nerf Commandos damage buff but make it STACK with either Gunslinger or Rifleman. This way automatics are a viable choice again wi
