If you saw sleeper 2010 hit Monsters, you'll know that despite being about a giant...monster, you don't actually see much of it. It's very quiet, very tense. Four years later the movie has a sequel, and that soft approach has gone right out the window.
Monsters: Dark Continent takes place ten years after the first movie, and the giant creatures are now spreading all over the planet. It focuses on a squad of US soldiers, all fresh recruits, as they see their first action in the Middle East.
And that action is basically a lot of people shooting at a lot of very large monsters.
