Title: Retribution
Description: It's been several months since the events of Earthfall, yet Sam's attempts to rouse the enslaved people of London from their trance-like state have frustratingly failed. Worse still, the enormous Voidborn drilling device which Sam and his friends disabled in London was one of hundreds scattered across the planet, all nearing the final stages of construction. Joining up with another resistance group, they plot to disable a drilling machine in Tokyo and in the process implant viral commands that will cause a catastrophic failure of the entire network. Just as that mission appears to have been successful, Sam and the others are double-crossed by the resistance leader.
