Good, they should move away from RPGs entirely now that they've got their feet wet in the action game genre.
I hope we get a male protagonist this time around, this circle does pretty good female enemies.
Are you thinking of reverse rape or basically something like this but the POV reverse to be on the villain side? Because given the fetishes this circle focus on an action game where you play as a villain trying to use traps/minions(from generic mook to converted females) and other stuffs to try and corrupt an attacking heroine is definitely possible.
Just imagine it: You're the mid-boss villain who will get your ass kicked in a straight up fight, and the heroine is coming straight to your base.
You start out in waiting, setting up traps and personnel throughout you base.
Then when the heroine get in, you basically try to do things to her while she's distracted by all the other things you've set up.
You can repel her outright, or setup just enough defense that you have time to apply some hypnotism/brainwashing on her, and move further into the base.
Then once she get deep enough, fight back hard enough for her to try and run, at which point you release your hypnotic gas in the path to the exit to do more mental damage.
If the author is willing to work with the idea of more than victory/defeat and expand 'but/and' into it, it can have some very interesting content.
For example, take the outer most perimeter:
Victory But - you do enough damage, but too quickly and so she escaped from the area without any lasting damage
Victory And - you do enough damage to knock her out, so you get some 'training' time to apply more brainwashing on her
Lose But - your army on the perimeter is defeated, but you escaped inside, so now she's chasing after you
Lose And - you get caught and is thrown into prison, where you'll eventually escape somehow but it still cost you time where the heroine's corruption might recover or the boss might cut your funding.
And depending on how deep it is in the base, the result can be more varied.
Like if instead of fleeing, she goes into a last stand powerup mode and you need to survive for a time, either subduing her or until she do enough damage to the base that she can flee.
Or when you lose but manage to get away in an escape pod, you avoided the prison time wasting, but the boss will cut hefty amount off your pay for repair and for failure.
