I’ve an idea for a boss.
The Construct
“An attempt by humanity to turn the Turned against themselves, the Consruct is a horribly disfigured amalgamation of flesh and technology. It prowls the underground tunnels of the research center it was created in, eviscerating human and Turned alike.”
Basically it’s fast. Really fast. Its implants calculate trajectories and sightlines in such a way that it can intercept grenades and other thrown weapons using mechanical limbs and tentacles and toss them back. Similarly, it can dodge shots from precision weapons such as sniper rifles.
Visually, it’s humanoid, with a hunched back and roughly 40% of its body composed of machinery. It’s also relatively intellegient, and sets up ambushes within the confined passageways for unsuspecting victims. As it is both cybernetic and biological, it is weak to both EMPs as well as temperature extremes.
When half of it is destroyed (either the cybernetic or the biological half), the surviving part will lash out with either electrified mechanical limbs or spore-releasing tentacles.
Something a bit like this:
