It looks like they added an original character in this episode, some sort of pigman with pointy ears. It's not the thing from the animal farm stage. They look distinctively different.
No idea what their intentions were for this; they have an overabundance of unused source materials from the game. They could have easily snagged something from somewhere. Why add that?
They yet again waste excessive amount of runtime on depicting guro. At this point, I am not sure if this is hentai anime or poorly made ketchup fest. Though the game is very guro-oriented, there is no reason to put so much focus on Rabiane getting physically tortured to death when each episode runs for less than 15 minutes.
One thing that stood out is every reddish tentacle/worm thing that should have appeared in this episode got replaced with small grey worms which doesn't show up until later stages. Maybe they really do intend to make episodes all the way? I am saying this because the grey worms take up the main plot of the series and the rest of the monsters and cultists are just fodders for them.
