These values are located in a file called hfperks.xml.

Gaining access to this file is a multi-step process.

• First, you use a 'de.pak'er on the Homefront: The Revolution.exe, creating a directory called 'extracted', inside are numerous game files, such as textures, sounds and animations.
  
• Finally, before hfperks.xml is usable, it needs to be decrypted, achieved using HappyXML, which requires certain Yarhl components.

Tools used

• .pak Extractor[forum.xentax.com]
  
• HappyXML[github.com]

This is where I will list recent changes to the guide.

• Having recently purchased the Expansion Pass, I can now reveal without a shadow of a doubt the perks associated with the new G-Man, US Marshall and ATF Agent, which come from the DLC, The Right Kind of School.
  
• I am currently working on making this encyclopaedia more accessible, through various TLDRs and shortening and reformatting existing content, as well as properly exploring the implications of various values.
  
• Also, in future I will also separate builds into a separate guide, which will be shorter and only offer key information rather than information in a mind-numbing plurality.
  
• Added access to commented hfperks.xml

Before you read any other values it is important to familiarize yourself with the value limits, below reveals the maximum range in which stats can be affected. Either an increase, reduction, adjustment or multiplier.

Global Damage (Armour)
Incoming Damage can only be reduced by 50%, requiring +100% Armour, which is only achievable with full Bling Armour, meaning 95% Armour, and -37.5% Mobility, and the Personal Shopper Background Skill.

Health
Health can be increased to its cap of 50%, by using the following skills Tough (+10%), Grizzled (+15%) and Badass (+25%), gear cannot be used to increase max health.

Revive Health (Self) v
Functionally caps at +75%. As even using all available methods of the Labourer Background (+20%), either the Desert Tactical Helmet or Philly Hogs Tactical Helmet (+30%) and the Back from the Dead Tactical Vest (+25%) cannot reach the supposed 100% limit.

Bleed Out Time
Can be increased to its 50% maximum, using a combination of the following methods; Stevedore Background Skill (+20%), the Tiger Print or Splinter Tactical Helmet (+30%), the Death's Head and Grizzly Tactical Vests for (+25%) or the Camo Flak Vest for (+20%). As an earlier alternative, using the two armour pieces to reach 50% is preferable.

Mobility
As a gear stat, Mobility combines Crouch, Walk and Sprint Movement Speed, I suspect the displayed Mobility is 3 times greater than the movement speed buff actually applied. However, with skills I have confidence in their exact values.

Additionally, Sprint Stamina includes Sprint Speed and generally has a 5% increase to Sprint Dash Move Speed.

In regards to gear, boots can increase Mobility from 10% to 22.5%, kneepads often directly target Crouch Movement Speed from 10% to 15% and vests can increase mobility from 7.5% to 15%, resulting in around +52.5% just from gear, which caps all forms of standard movement speed.

Crouch Movement Speed
Caps at 50% and is increased in the following ways, with skills Power Slide (+50%), Fleet Footed (+25%), Pharma Quickies (+15%), after a Pharmacist's revive (+33%), and an Adrenaline deployable (+33%).

Walk Movement Speed
Caps at 33%, being increased by Fleet Footed (+25%), Pharmacist Resuscitation Buff (+33%), Adrenaline Boost (+33%) and Quickies Pharma (+15%), and is of course affected by gear.

Sprint Movement Speed
Caps at 33% and is increased by Fleet Footed (+20%), Pharmacist Resuscitation Buff (+33%), Adrenaline Boost (+33%) and Quickies Pharma (+12%), and is additionally affected by gear, presumably by both Sprint Stamina and Mobility.

Sprint Dash Move Speed
Peaking at 10%, gains (+5%) from Fleet Footed, (+10%) from Adrenaline, (+2.5%) from the Quickies Pharma and presumably increased with the use of Sprint Stamina on gear.

Slide Max Distance
Can be increased by 100%, functionally only 90% as Power Slide (+50%) and kneepads increase from +20% to +40% Slide Distance.

Slide Deceleration
Reducible by 50%, an exploration of characterparts.xml revealing kneepads have roughly half their Slide Max Distance as Slide Deceleration with 20% Slide Distance getting 10% Deceleration, 30% meaning 20%, and 40% with 25% Slide Deceleration.

Climbing Speed
Can be increased by 50%, with the Parkour skill (+50%) or various kneepads which range from 20% to 40% Climbing Speed. Either get the Parkour skill or deal with a 10% reduction of Climbing Speed.

Takedown Speed
Can be increased by 30%, the Knife Fighter skill achieves a 25% increase, and various gloves provide a 10% to 20% increase. Much like climbing speed, a choice between the skill or using gear needs to be made.

Stealth
While Stealth is undoubtedly broken in Homefront: The Revolution, I still want to explore what Stealth stats on your gear actually mean, analysis has revealed the displayed value is actually 4 times less the actual value applied, for example the Shadow Tactical Helmet says +60% Stealth, this instead results in a +15% to both Stationary and Moving AI Player Detection.

AI Player Detection (Stationary)
Presumably the rate of detection when stationary, can be multiplied by up to 50%, ie halved, being increased with the following skills, Camouflage (+40%), Concealment (+20%) and the Pharma Cuttlefish (+10%).

AI Player Detection (Moving)
Multipliable by 25%, increased by the skill Concealment (+20%) and the Pharma Cuttlefish (+10%).

Footstep Reduction
Referring to the 'noise' of your footsteps, which can be reduced by 25%. The skill Light Footed can be used to affect the FootstepStimRadiusMultiplier by a scale of 50% and various boots can be used to reduce the FootstepStimRadiusMultiplier from 15% to 35%, creating the following calculation of FootstepStimRadiusMultiplier = 0.325 = 0.5 x (1-0.35).

Fall Damage Reduction
Can be reduced by 50%, the skill Tuck & Roll reduces Fall Damage by 33%. Alternatively, boots can be used to reduce Fall Damage by either 10%, 15%, 20% or 25%.

GTK Build Time
Can be reduced by 75%, with the Armourer skill giving a 66% reduction and various gloves enabling a further 15% or 25% reduction.

Weapon Customization Speed
Can be halved, with Armourer providing a 20% increase, and the ATF Agent background providing +15%, while gloves can be used to gain an additional 10%.

Heal Speed
Improvable by 66%, First Aid skill provides +50% and gloves can provide either +15% or +30%.

AI Vs Player Accuracy (Dodge)
Maxes at 15%, the Background Skill Dancer reduces by 10% and the only other item with 'Dodge' the Tiger Print Boots provides the final 5%.

The stats and values for gear are openly available, making this section very cut and dry.

The one exception to this is Armour, whenever you see an Armour Value, halve it and you end up with the real Global Damage Reduction it is really achieving.

Proof of this comes from the Red Rebel Helmet.




Which says it has +5% Armour. While, hfperks.xml, shown below, reveals Global Damage Reduction to equal 2.5%.
