A group of meteorites suddenly landed on the earth. Strangely, they began to fall slowly before crashing into the sea. There is no doubt that this was intentional. It turned out that aliens are attacking the earth, and their purpose is to plunder the water resources on the earth. Each meteorite contained a mechanical body, and after these mechanical bodies fell into the sea, a large number of unknown creatures appeared in the sea. These unknown creatures held weapons and began to massacre after landing. Coastal cities in 12 countries were devastated. Los Angeles, which survived the disaster, immediately assembled its troops to fight back. Lieutenant William Martinez was ordered to lead a group of soldiers to form a small team and go to a police station on the west side of Lincoln Avenue to rescue the trapped civilians. They had to complete the rescue mission within three hours, after which the Air Force would carpet bomb the area. And the aliens they face have sophisticated weapons that can carry out devastating blows to ground targets. Can this group of inexperienced fighters complete the rescue mission within three hours and break through smoothly
