Character, Setting and Environment.

We've stumbled upon a great idea for our protagonist that we're keen to stick with now: The player will control a hybrid human/alien, but won't initially be aware of this fact.  We'll use intricate (and blunt) moral dilemmas and suppositions throughout the game that will force the player to think about his/her position, whilst subtly and gradually allowing the player to realise their origins.  We're thinking of adding an alternate timeline/ending based on choices made throughout the game.  This will have to be carefully considered as the player will initially and automatically side with the humans (obviously, unless they're some kind of alien sympathiser sociopath).  Sorting out ideas for how we'll approach story development. More on that soon.
