Draugr

The Draugr is an evolution of the shambler previously known as Strangler. This humanoid shambler was known for wielding weapons in their hands during battle, and its evolution only took that trait a step further. Still possessing functioning opposable thumbs and immaculate finger strength, the Draugr is known to wield various weapons in battle, from simply picked-up pipes and wooden boards over to wood chucking hatchets, kitchen knives and even sometimes modified melee weapons previously belonging to the person the Draugr emerged from. Additional to that, the Draugr's skin is known to absorb armor worn by the former survivor turned into a Draugr - seeing a plate of Ar500 steel or Kevlar embedded into a Draugr's chest isn't a rare sight.

Lastly, the Draugr possesses an incredible aggressiveness - once it spotted you, it will relentlessly pursue you, attacking you with everything it has. Shooting off or immobilizing limbs would prevent a normal shambler's attack - a Draugr would simply throw itself at you nonetheless, going for a bodycheck move instead of a melee slice.
