Got TTS working but noticed it reads UI elements and such so its not very useful in this game. (since it would be annoying)
I guess if you go protoss route the game more or less ends there instead of continuing into what I assume is Chapter 3.
It would be nice if there was some sort of small heads up explaining the intent of the protoss option; basically its a feel good option where Sarah escapes and gets some sort of normal life back but ultimately ends the game.
