Earth Taken 3 screenshot #3!
My character is actually hiding behind that big pillar, just to bring the focus more to the surroundings. Background characters like these two survivors hanging out at a fire, will often have little conversations with pop-up text like this. They will talk about things like their general mood, their current situation with the alien invasion and so on. They will warm themselves at the fire, drink, cough etc. This is all mostly for atmospheric purposes and I feel like it makes the whole game and the people in it feel a bit more alive.

Oh, this is a part of Greenhill shelter by the way, a safe haven located underground in a subway station.
