In The Outlast Trials, danger wears many faces – but few are as unforgettable (or unavoidable) as the Big Grunts, also known as the Heavy Ex-Pop. These massive, biologically modified monsters are Murkoff’s answer to subtlety: big, loud, emotionally stunted tanks who will chase you through hell just to hear “good job” from Dr. Easterman.


💉 Bio-Engineered Brutality

Unlike the more disposable Ex-Pop grunts, Big Grunts are considered assets. Their origins? Murkoff records tie them to a redacted military facility (possibly Los Alamos) where they were subjected to horrifying experiments including:

  • Hormone injections
  • Limb-extension surgeries
  • Psychological infantilization

The result: towering mutants with grotesquely stretched features, inhuman strength, and a deep-rooted need for praise.


🧠 Built to Obey, Programmed to Please

Murkoff didn’t just build killing machines – they built children. These oversized maniacs believe in fairy tales, fear punishment, and refer to Dr. Easterman as “Daddy.” Fail a hunt? They cry for him. Succeed? They beam with childlike joy.

The twisted genius? Their psychological state makes them controllable, but unpredictably volatile. Staff are explicitly warned: No contact near sensitive areas. Provoking them (even by accident) can lead to an immediate, violent, and possibly sexual response.


🗣️ Personality, Power, and Presence

Big Grunts may share muscle mass, but not mindsets. You’ll encounter:

  • Snarling beasts who speak only through rage
  • Southern-accented giants who flirt between punches
  • Playful female variants who show disturbing moments of clarity

But make no mistake: every Big Grunt is a threat. They might seem slow, but they’re relentless. Once they lock onto you, it’s not over until you’re unconscious or dead.


🔥 Big Grunts In the Trials

In gameplay, Big Grunts act as area denial units. They:

  • Chase Reagents across wide zones
  • Smash through cover
  • Ignore minor distractions
  • React with terrifying persistence when triggered

You’ll hear them coming and wish you hadn’t. If one joins a Trial, stealth becomes essential and split-second decisions could save your life.


🎬 Final Thoughts on Big Grunts

Big Grunts are the physical embodiment of Murkoff’s cruelty – monsters molded from innocence and pain. Their twisted identities and emotional instability make them one of the most memorable threats in The Outlast Trials. And when they scream for Daddy, you better pray you’re not who they’re running toward.
