I'm starting to think that this game has less of a focus on story compared to the first game, and I think the silent protagonist solidifies that theory.
The first game had a pretty basic story, but at least it was still notable. The premise of this game just seems to be getting used to a new homeland.until the ending
It looks like they want to focus more on exploration.
There is going to be a lot to the story, it's not going to be about surviving on an alien world. For example, why did those two alien species start a war outside of Earth? It couldn't have been just for the planet because then why follow the escapees two years through space just so they can completely kill them off? It has a Battlestar Galactica feel going. So why do these aliens want humans seemingly extinct?
We have seen so many different races so far, some friendly with humans apparently. Who are they and were they natives to the planet? Are they on the run from the killing alien species too? Were there any other survivors that made it from Earth?
And you know there are going to be so many twists along the way.
