___________________________________________________________________________
FEATURES:
*Permanent bodies
*Longer lasting blood (at least some of it)
*Dismemberment will happen on more attacks (as enabled by Dishonored Unleashed)
*Every attack that could potentially dismember will dismember every single time
___________________________________________________________________________
Differences from Dishonored Unleashed:
*No tweaks to the stealth system (I like the way overpowered leaning)
*More frequent dismemberment
