Project: Snowblind

In 2065, a militant regime called the Republic led by the rogue General Yan Lo attacks Hong Kong. An international peacekeeping force stationed in Hong Kong, known as the Liberty Coalition, is tasked with defending the island from the invasion. New soldier Nathan Frost arrives just before a major attack leaves him near death. Granted experimental nanotechnological augmentations, Frost is put in charge of the Coalition's effort to defeat the Republic and killing Yan Lo. They eventually rescue defecting scientist Joseph Liaw, who reveals Yan Lo's plan. Believing technology is weakening humanity, Yan Lo has initiated "Project: Snowblind"; he plans to detonate EMP bombs in New York, Paris, and Hong Kong, destroying the world's technological hubs and triggering a new Dark Age.
In an attempt to stop Project: Snowblind, Frost spearheads a controversial assault on Yan Lo's underground bunker with Liaw's inside knowledge, fighting past Yan Lo's elite augmented guard. He eventually faces Yan Lo, discovering that he is an augmented soldier like Frost. Created twenty years ago using an earlier generation of mechanical augmentation, Yan Lo was driven insane by the technology's painful side effects, fuelling his hatred of technology. Frost manages to fatally injure Yan Lo, but he declares that Project Snowblind will continue before blowing himself up.
In a final attempt to stop Project: Snowblind, Frost launches a final assault on the facility where the EMP bombs are being prepared for distribution, aided by the surviving Coalition soldiers. While his forces hold off the remainder of the Republic forces, Frost enters the facility and destroys the EMP bombs, disconnecting his own augmentations so he can survive the resultant EMP shockwave. The final scene shows Frost and the survivors, including Liaw, walking to the nearest functional Coalition base fifty miles away.
