In 2028, Blue Star is no longer the only home of mankind. The iron hooves of the alien civilization "Reaper" crushed the prosperity of the past. The top anchor team that once dominated the "Operation Delta" game - Bai Ze, Dong Yao, Xiao Xiaoyan, Dong Guai, Qingchuan, faded away from the halo of the virtual world, put on military uniforms, formed the "Starkiller Squad", and became warriors to protect their home and country.
They used to work together well in the game, but in reality they had to face the fangs of alien monsters: swift reptile species, fierce elite species, terrifying hunter species, and even compatriots who were alienated after being parasitized. In an accident, Bai Ze activated the "tactical system" that has the same origin as "Operation Delta". After completing the mission, you can unlock props and skills in the game - Dragon's Crouching Tiger Cannon, Red Wolf's Overload Mode, Shepherd's Quantum Shock... These powers that were once used in the virtual battlefield have become their sharp blades against alien invasions.
As the core skills were unlocked one by one, they gradually discovered that the Reaper's goal was not to plunder resources, but the "star core" hidden deep in the Blue Star, and the five of them might be inextricably linked to the "key" that unlocks the star core. The mole in the military, the infiltration of parasites, the secret of the star core... Many crises followed one after another.
