Uh what is this mcs-x again? How do you make it? I don't recall ever seeing it
You obtain the mcs-x at the end of the game (currently), once you are at the end (when the game tells you you're at the end) go to the lab and read penny's notes, you are now able to create the mcs-x.
The mcs-x is kind of a "bad ender", once you use it on a character they're locked in a bad end.
In previous version of the game, you could use it to make ava so broken-minded that she had to be taken by the company, erasing her from your game, you could also make dakota become a pornstar, making her leave the house to "acheive her dream", again, erasing her from the game.
As of now, the mcs-x doesn't do much, since, like i said earlier, only dakota and ava have one, and they're... i will say nicer than the previous ones.
Right now (from memory) you can have dakota be your dom/sub or a camwhore, but she's still in your game, as for ava, I don't remember.
Take it that way, the X serums are an "end" to someone's path, it could be good or bad (but they're supposed to be mostly bad afaik).
