Attack of the Titans

A soldier in a brown uniform uses a maneuvering gear system to swing through the air, followed by a close-up of a man's face in shock, then a soldier in a green uniform lunging forward with a blade, another soldier leaping through a dark corridor, a soldier soaring through the sky with a blade, and finally a massive explosion in a city street. The setting shifts between an urban environment with buildings and a sky with clouds, a dimly lit interior with torches, and a dark corridor.
