Loving the new base. It really nails the feeling of an old government/research building that's seen better days. Not sure if this has been touched on already, but now with the expanded base, parking lot, etc., the area around it feels a little too small. Looking at the bridge, road, and tight space around the base feels like there's no way you'd be able to get a car in there to park it, let alone a truck to use the loading dock. Maybe this is already going to be addressed in the future, but I also think that adding an actual paved road (even broken or in disrepair) from the checkpoint entry up to the base and making it pass over a larger bridge would add to the 'immersion' of being in a place that was once heavily used but is now almost abandoned.
Also, I had the thought that it would be freaky as hell if you were returning to your base or walking around outside it and suddenly could see someone who looks like you standing in a window or sitting in your chair... like a doppelganger type thing.
Great game! The atmosphere and sandboxy gameplay are top notch.
