While there could be more options at the end, particularly various shades of being a bit evil, there are a lot more than 2 endings in what’s shown.
And I’ll never really understand why people need a recap of the choices they made. You know what you did, right?
It's not a recap, it's about closure. And the endings are not more than 2. You dominate the brain or you get it to turn off. The rest is window dressing. And the worst part is that the window dressing has barely any variation. Someone has to go octopus or eat brains. That's it.
