Please come in if you are familiar with the story of ps3 killing zone.

Hal geist was once a group on the earth. When the earth's resources were about to run out, it immigrated to the universe through UCA (a joint organization) and colonized two planets. Later, because the planet's resources were too rich, it made a fortune, but the excessive pursuit of independence triggered a war with UCA. After the defeat, it didn't get the treatment it deserved, but was deported to Haier Xinggang, where the environment was bad and the disease took most people's lives, so it was put on a mask.

Later, the descendants of Haier gang gradually adapted to the environment. At this time, one of them stood up, the one who was finally killed, and announced that they were no longer human beings, but Hal geist, vowing to get back what originally belonged to him. The mask was a symbol of the weak at that time, and was later defined as a soldier ~ In the killing zone, you can define Hull geist as a German and Issa as an ally.

The second generation story tells the story of a generation of Hull geist who was defeated in the battle and was countered ~
