This is an open world 3D gunfight game based on the law of the jungle, which emphasizes the survival of the fittest. It is also a mission centered combat game based on experience leveling. It combines elements of role-playing, tactical strategy, and experience leveling.

1、 Background of the story:

      In 2999, when the first alien mother ship tore apart the atmosphere, humans realized that this disaster had been brewing for many years. Those alien hackers invaded the human space station, releasing a millennium worm that paralyzed the intelligence and communication satellites controlled by the space station, causing communication on Earth to be completely paralyzed. Those unidentified flying objects lurking in low Earth orbit suddenly subducted collectively, like a meteor shower, crashing into major cities around the world. Their hulls are covered with bio metal shells, which release high-frequency pulses at the moment of impact, instantly paralyzing all electronic devices. The screen suddenly went out, the speeding cars collided like they lost control, and the hospital ventilators collectively shut down. The skyscrapers in Shanghai collapsed in silent shaking, and the glass curtain walls poured down like a waterfall. Not only did an alien army emerge from the belly of the mother ship, but countless alien creatures were also mixed in. They melt their bodies into weapons, and the concrete in front of them is Rice noodles.

      In the context of such a large-scale attack, the only survivor and maintenance worker of the nuclear power plant, Yichun, continuously battles with extraterrestrial creatures through underground shelters, and finally discovers that the fatal weakness of extraterrestrial creatures is energy: especially extraterrestrial creatures rely on nuclear waste fuel for energy, prefer to survive around nuclear waste water tanks, steal leaked nuclear fuel for survival and continuous reproduction, causing a continuous gathering and explosion of extraterrestrial creatures in the ruins of the nuclear power plant. Therefore, survivor Yichun adopted the plan of cutting off the energy supply of extraterrestrial creatures as the best strike mode. We decisively adopted the dangerous plan of discharging nuclear wastewater from the nuclear wastewater tank. Therefore, the first main task is to shut down the leaking nuclear power plant waste water tank. Without the supply of renewable energy, the attack power of extraterrestrial mechanical creatures was halved, and finally all the mechanical creatures around the nuclear power plant were eliminated.

      But the real crisis comes from within - some politicians collude with aliens to assist alien hackers in infiltrating the space station, and make dirty deals, signing humiliating and dirty agreements, attempting to become puppet rulers of Earth. One of the tasks is to search for this agreement and make it public.

      Female hero - Yichun, she will infiltrate a terrifying hospital to rescue Doctor Blast [Bernaste] who was kidnapped by aliens, and obtain the anti radiation medicine - Nuclear Radiation Ning; She will launch a street battle to break into the alien freezer and rescue her boyfriend Aladdin, who was frozen by aliens for experimental research, and so on. Continuously challenging strong enemies to complete tasks, demonstrating heroic qualities to save the earth, and ultimately achieving the rise of humanity .....

2、 Plot design:

      A physical sandbox game that allows players to repeatedly battle in revenge and collapse. By eliminating alien monsters and guards in real time, completing challenging mission goals, unlocking new levels, and combining a high degree of freedom destruction system with story narrative to advance the plot.

Core driving force

      The main goals pursued by players are to rescue imprisoned doctors and scientists, liberate enslaved humans, seek revenge and eliminate alien invaders on Earth, and advance the plot. The driving force includes completing tasks to unlock new areas, collecting resources to upgrade equipment, and experiencing the growth story of hero Aladdin, immersing players in the tension of resistance and survival.

      The gameplay loop is repeated by players: infiltrate/explore alien space stations (or spacecraft) → use physical sandbox mechanisms to destroy the environment or eliminate guards → complete mission objectives (such as rescuing scientists or destroying facilities) → unlock new levels or upgrade skills → explore higher difficulty areas again. Each cycle strengthens the player's strategic choices and combat skills.

      Level 1: Close the protective cover of the nuclear power plant. Before the alien attack destroyed Earth, nuclear power plant engineer Izumi happened to be wearing protective clothing while inspecting the fuel pool of the fifth nuclear power unit, which was more than 500 meters underground. Although the sturdy underground nuclear protection wall avoided a powerful external nuclear attack, the internal nuclear power unit suffered minor damage and fuel leakage slowly occurred. Yichun escaped by chance and arrived on Earth. The surface of the Earth was already in ruins, a scene of the apocalypse. Yichun's mission is to continuously eliminate infiltrating alien monsters, find the nuclear power plant's protective cover switch, and complete the tasks of discharging nuclear wastewater and closing the protective cover;

      Level 2: Rescuing doctors and scientists. Aliens have scattered and imprisoned human scientists in their different laboratories, excavated human civilization through continuous analysis, and further improved the technological strength of aliens with human progressiveness technology. Yichun's mission is to infiltrate the alien science laboratory, eliminate alien guards, and rescue scientists;

       Level 3: Control the energy harvesting and refining base to rescue enslaved humans. Aliens imprison ordinary humans who have survived by chance in their different resource collection sites, serving as laborers to gather and extract energy for the aliens, and supplementing their daily needs by constantly plundering human resources. Yichun's mission is to infiltrate the resource collection base, eliminate alien guards, and rescue enslaved humans, with humans ultimately controlling various energy collection sites;

      Level 4: Find the humiliating ball selling agreement and regain control of the Earth Control Center. Yichun's mission is to infiltrate the Earth Control Core Base, explore and find a ball selling agreement signed between a politician and aliens, eliminate alien guards, and regain control of the Earth Control Center;

      Level 5: Drive the space shuttle in the hangar of the Earth Control Center, land on the human space station in space, defeat the alien hacker team, repair the communication satellite in a timely manner, and complete the full achievement to achieve the rise of humanity on Earth.
