Mutant
Vj Jingo Sci FI 01h 32m 1 year ago

In 2150, artificial intelligence mutated and replaced humans' control of the earth, and launched an eradication operation against humans. The surviving humans united together to form a resistance army, and with simple weapons, they fought a desperate battle with the artificial intelligence army.
