I call the Grunts either BlargBlarg (per my gf's suggestion) or Gatherers (I remember a note about local folklore mentioning something about Gatherers...and at the time I assumed it was referring to the monsters). I call the Waterluker...well the Waterlurker. And Brutes..I'm fine with Brute.
Shambler.
Howlers.
Magickarp.
I called them Servant Grunt and Brute Grunt due to file names in entities/enemy
I've been calling the grunts 'wookie men' or to give them their full name 'Evil naked blue zombie-wookie men' >.<
It made sense at the time...
Male S&M escort found dead after fourteen days. Portrait of the man painted by the dude who made the Melting Clocks.
Well, the official names in the files are Grunt, Brute, and Water Lurker.
The Water Lurker is also referred to as the Water Horror and it's actual name the Kaernk.
The Grunt is
I have no idea what the Brute is. There is one flashback that mentions a man being tortured calling Alexander a brute. I believe this man to be the captain of the guards sent to investigate Brennenburg.
For fun my friend and I renamed everything. We named the Grunt "Mr Sacky", The Brute "Tinny", and The fleshy stuff "Grace".
I called the grunts "bondage zombie"
The waterlurker.. "Vattengrejen" (Waterthingie)
The Brute... I don't think I called it any specific.
It's nice to see what people thought up for all these, makes the game seem more like a personal journey :D
Anyways, for me I went with (when talking to friends about the monsters):
Bloodsucker 2.0/Baghead for grunts/open jaw dudes
0% opacity monopedal demon (turns out he's an exercise ball, so it's even more ridiculous than I thought : P)
And Sawhand, because the brute left me too terrified to think of any clever names while he was EATING ME.
How are they making kids?
