Hi! I watched this movie 4 years ago but I can't remember it's name now. Details:
Alien invasion from a portal which was opened by army experiments or so. Action takes place in a mini-market store with big windows. The main actor is a man, that came with his wife, son and mother to the shop. Suddenly everything got covered in white (not snow but similar). People tied a rope around a man, and sent him to see what's outside, because the fog was to dense. There was a monster that pulled the man and broke him into 2 pieces. People inside pulled the rope and saw only his legs. The main actor reached his car, in the parking lot, and travelled with his wife son and mother. After some time, their gasoline ended. He had 3 bullets in his gun, so he shot his mom, wife and son right before the soldiers came. He cried really loud. The soldiers were burning everything was covered in white.
