Plot: Battlefield is a typical apocalyptic disaster movie, and it also has a very grandiose worldview in its setting. Humans are facing an alien invasion and have gathered soldiers from various countries to form a joint defense force. However, the mighty alien invaders nearly wiped out the human legion, and the few survivors, some became bandits, some wandered, and of course there were also heroic warriors who continued to cling to their beliefs and fought nonstop. A science fiction movie worth watching.
