Insectoid Invasion: I Became a Super Soldier

In 2077, alien insects invade Earth. Humanity is driven back at every turn and has no choice but to launch the God-Making Project ahead of schedule. Countries begin mass-producing super soldiers, but research into the super serum is still immature, and the soldiers cannot be produced in the numbers people had imagined. To ensure the survival of civilization, humanity builds underground bunkers and lives below the surface, plotting to reclaim its former home.

Note: Set in a fictional world.
