Continuing my late January 2022 playthrough of Extermination (livestreamed on Twitch), I ran around aimlessly between warehouses and lab sections (and eventually advanced the plot!! Haha). This game is absolutely a labyrinth of labs!
After some very dramatic character interactions, we encountered the first real "big" boss in the game, which was The Executioner! We were bested by it after fighting it over and over, and eventually I looked up a guide on how to defeat it...Turns out we just needed to use the knife weapon to beat it. And you bet there's more of this epic battle to be seen in the next installment! :)
Technical Reference: I captured the game using the RetroTink 5X-Pro (available at the below link) coupled with an ElGato HD60S+ capture card with RGB output from a Playstation 2 slim (running the original Extermination game disc). https://www.retrotink.com
