With the recent technological advances, humans have achieved lunar colonization. Meanwhile, humans have established a joint scientific research institution on the moon to conduct scientific research.

Through controlled nuclear fusion technology, humans have successfully obtained fuel from lunar rocks for nuclear fusion and realized wireless power supply and artificial gravitational atmosphere to ensure that the oxygen and pressure around the base are maintained at near-earth levels.

Due to anomalies in the moon's orbit, the human base on the moon is frequently attacked by unknown creatures. Currently, humans have evacuated the relevant personnel of the lunar base. Now, as a military scout, you are sent to the moon to investigate the anomalies and find solutions to the problems.
