The existence of aliens is one of the things that people have always doubted about and even fear of aggression from them. And that actually happened when a group of aliens used flying objects as well as brought some heavy weapons to attack the Earth. They were annihilated shortly afterward, but no one knew whether this danger had actually ended or not? Sometime later, several messages warning the return of aliens again had been sent to Earth. Scientists had identified the location, which is from Mars. A plan to eradicate these dangers was devised as an agent was chosen to carry out this noble mission!
