At the 22 second mark in the trailer this screenshot was pulled showing what could possibly be an alien figure off to the left side of the screen. It appears to be the face/head of what most people would describe as an alien being. It is gray and has a large skull and larger oval shaped eyes. Now, I'm not sure what we're seeing here, it could just be smoke playing tricks on our eyes, but it does sort of resemble an alien. However, that being said, I don't think this is the creature that is trying to break out of the box car on the train. The creature contained within that car seems to be a lot more powerful and probably a lot bigger than just an alien being. I think we're going to be looking at an actual creature and not just an alien "humanoid" when all is said and done.
So again, this could just be our eyes playing tricks on us and our brains making us see what we want to see, but it's the start of the campaign so I figured that everything is fair game for right now until we can prove otherwise (possible with an official version of the trailer). So what do you guys think?
Thanks Brett for commenting on this and user wildoofsmeg at unfiction for the screenshot.
Update: commenter Kidanny has posted up another screenshot which some are saying looks more like an alien than the above, but honestly the more I look at both of them it just looks like smoke or the middle of a transition in the frame, but you be the judge. I've posted Kidanny's screenshot after the jump.
